thing<\/h2>\n<p>Our brains are also physical, apparently inert grey goo, yet full of electrochemical activity running through networked neurons and flooded with neurotransmitters. Three different kinds of physical process working together: electrical, structural (connectivity) and chemical.<\/p>\n<p>In the 19th century, many believed that one could tell a person&#8217;s character and skills through the shape of the skull, reading &#8216;bumps&#8217;.\u00a0This study of &#8216;<span class=\"touchit_term\"  ix_rawcontent=\"phrenology\">phrenology<\/span>&#8216; did make sense: if the <span class=\"touchit_term\"  ix_rawcontent=\"brain\">brain<\/span> is the seat of character and intellect, and if some parts of your brain are bigger then normal, then surely this should be able to tell you about the person. In fact, we now know that even gross measurements do not correlate well with specific abilities. For example, the total volume of the brain typically varies between individuals by up to 50 per cent, but there is no connection between this and intelligence.<\/p>\n<div class=\"touchit_figure\"><a name=\"fg:4.1\"><\/a><!-- link_id --><a name=\"fg:phrenology\" class=\"xref_label\"  xref_local=\"fg:phrenology\" xref_label=\"fg:mind.phrenology\"><\/a><a rel=\"noopener noreferrer\" href=\"http:\/\/en.wikipedia.org\/wiki\/Phrenology\" target=\"_blank\"><\/a><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-2462 \" src=\"https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/07\/PhrenologyPix-1-822x1024.jpg\" alt=\"\" width=\"308\" height=\"383\" srcset=\"https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/07\/PhrenologyPix-1-822x1024.jpg 822w, https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/07\/PhrenologyPix-1-241x300.jpg 241w, https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/07\/PhrenologyPix-1-768x956.jpg 768w, https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/07\/PhrenologyPix-1.jpg 1000w\" sizes=\"auto, (max-width: 308px) 100vw, 308px\" \/><\/p>\n<p><p class=\"touchit_caption\"><span class=\"touchit_label touchit_label_figure\"><span class=\"label_prefix\">Fig.<\/span> <span class=\"label_counter\">4.1<\/span> <\/span>   Phrenology &#8212; early attempts to understand the brain <\/p><\/p>\n<p><a name=\"note:1\"><\/a><span class=\"touchit_comment touchit_source annotation\"> http:\/\/en.wikipedia.org\/wiki\/Phrenology <\/span><\/p>\n<p><\/div>\n<p>However, while the raw size of parts of the brain is not related to specific traits or abilities, the physical parts of the brain do perform different jobs; there is functional separation. This was first discovered through accidents involving traumatic injuries to parts of the brain, or through tumours that affected specific parts of the brain. Nowadays the locations of these would be determined by X-rays or brain scans, but in the early days doctors often had to wait for the patients to die to study the brain during an autopsy.<\/p>\n<p><span class=\"touchit_term\"  ix_as=\"surgery\" ix_within=\"brain\" ix_rawcontent=\"Brain surgeons\">Brain surgeons<\/span> now use this knowledge to avoid damaging areas associated with critical functions such as Broca&#8217;s area and Wernicke\u2019s area, which are essential for different aspects of language. However, the same surgery has also offered fresh knowledge. While the broad <span class=\"touchit_term\"  ix_as=\"structure\" ix_within=\"brain\" ix_rawcontent=\"structures\">structures<\/span> of the brain are roughly similar between individuals, the details vary, and in order to determine precisely the limits of critical areas surgeons will often use a probe to administer tiny electrical impulses to different parts of the exposed brain. The patients, still awake despite having part of their skull removed, perform simple tasks. If the impulse disrupts the task, this tells the surgeon which areas to avoid, and in the process reveals more about the fine structure of the brain. For example, stimulating an area may trigger a particular <span class=\"touchit_term\"  ix_rawcontent=\"memory\">memory<\/span> of an experience.<\/p>\n<p>Modern <span class=\"touchit_term\"  ix_as=\"scanning\" ix_within=\"brain\" ix_rawcontent=\"brain scanning\">brain scanning<\/span> has allowed scientists to study the patterns of activity of the brain less invasively. In one example, which reveals the rich nature of <span class=\"touchit_term\"  ix_rawcontent=\"imagination\">imagination<\/span>, subjects are placed in a brain scanner and then shown a picture. The scanner shows the parts of their brain that are active in response, including the visual system and the other parts connected with the interpretation of the picture. Then the picture is removed and the subjects are asked to <em>imagine<\/em> the picture. A few new parts light up, but there is much in common with the pattern when seeing the actual picture. In particular, parts of the visual cortex light up &#8212; the imagining of the picture stimulates parts of the sensory system in a similar way to actually seeing it.<\/p>\n<a name=\"note:2\"><\/a><span class=\"touchit_note touchit_web annotation\"> BOX: fetal development of the brain, cortex as folded skin, the sea inside <\/span>\n<a name=\"note:3\"><\/a><span class=\"touchit_note touchit_web annotation\"> the children&#8217;s film Inside Out (Pixar) takes an interesting analogy of how the brain works, with memory &amp; emotion<\/span>\n<h2 class=\"touchit_heading\"><a name=\"sc:4.2\"><\/a><!-- link_id --><span class=\"touchit_label touchit_label_section\"><span class=\"label_counter\">4.2<\/span> <\/span> Memory and time<\/h2>\n<p>If we consider <span class=\"touchit_term\"  ix_as=\"types of\" ix_within=\"memory\" ix_rawcontent=\"memory\">memory<\/span> we see the importance of all three forms of brain physicality: electrical, connective and chemical <span class=\"touchit_bibcite\"  bibcite=\"KV09\"><a name=\"bibcite:1\"><\/a>[<a href=\"#ref-KV09\">KV09<\/a>]<\/span>:<\/p>\n<ul>\n<li><em>short-term memory<\/em> &#8212; Our fleeting thoughts are carried electrically, ionic discharges across synapses transferring information from neuron to neuron, as is measured through EEG monitoring.

We have approximately 10 billion neurons and each neuron connects to between 1000 and 10,000 other neurons, giving around 100 trillion connections. It is this pattern of connections that is normally assumed to encode our memories. Each of these neurons also has a strength of connectivity given by the size of the synapse.<\/p>\n<p>Now imagine a brain scanner in the far-off future that can trace each neuron, including how strong they are. As it reads the neurons it gives each one a number (needing about 34 bits) and records the connections and strength using a scale of 0 to 63. Together these require 5 bytes per connection. So with 100 trillion connections, our scanner of the future would need 500 trillion bytes, or half a petabyte, or approximately 500 hard disks, to store the neuron connectivity of a single human brain. Oddly, when the <span class=\"touchit_term\"  ix_rawcontent=\"Internet Archive\">Internet Archive<\/span> was set up in 1996, the dump of the web was about the same size <span class=\"touchit_bibcite\"  bibcite=\"Dx05\"><a name=\"bibcite:9\"><\/a>[<a href=\"#ref-Dx05\">Dx05<\/a>]<\/span>.<\/p>\n<p>You can do a similar calculation for the speed of processing, to see how fast a computer would need to be to simulate the brain running in real time. The figure turns out to be about 10 petaflops, that is 10 thousand million million calculations per second. Sounds a lot, but yes, you guessed, if you add up the processing power of all the PCs connected to the Internet, it is about the same.<\/p>\n<p>So in storage capacity and processing power the Internet is roughly similar to a single human brain!<\/p>\n<p>However, although the raw numbers are roughly similar, the web is not really like a brain (and the brain is not like the web). Our brains are relatively slow (around 100 &#8216;cycles&#8217; per second), but very highly parallel &#8212; lots of things happen at once. Each PC works much faster, several billion cycles per second, but serially, one thing at a time (although a 100 million PCs on the web is quite a lot of parallelism in itself!). Furthermore, the brain has a lot of non-local connections, that is neurons in one part of the brain talk to neurons in distant parts. This would make it very hard to actually emulate a brain on all those PCs, as the Internet in between would both be too slow and buckle under the load.<\/p>\n<p>Does the idea of simulating a brain worry you?\u00a0It is possible to simulate fluid flows, so one could model a glass of water, but running the computer simulation of the glass of water would not make you less thirsty any more than looking at a painting of a mountain stream.<\/p>\n<p>The difference between simulating water and simulating our brains is that some would say that our thoughts, minds, consciousness, indeed who we are, reduces to the <span class=\"touchit_term\"  ix_rawcontent=\"memory\">memory<\/span> patterns and &#8216;execution&#8217; of the brain functions. In other words, a computer emulating your brain is &#8216;just the same&#8217; as you thinking it in your head.<\/p>\n<p>Of course, these are things hotly contested in the <span class=\"touchit_term\"  ix_rawcontent=\"philosophy of consciousness\">philosophy of consciousness<\/span>, with some arguing that the special nature of neurons makes a difference <span class=\"touchit_bibcite\"  bibcite=\"Se97\"><a name=\"bibcite:10\"><\/a>[<a href=\"#ref-Se97\">Se97<\/a>]<\/span>. <span class=\"touchit_term\"  ix_as=\"Penrose, Roger\" ix_rawcontent=\"Roger Penrose\">Roger Penrose<\/span> even argues that it is the quantum effects of sub-cellular microtubules that allow us to think in ways that are not computable and therefore not able to emulated by a computer (except perhaps in a <span class=\"touchit_term\"  ix_as=\"quantum\" ix_within=\"computers\" ix_rawcontent=\"quantum\">quantum<\/span> computer) <span class=\"touchit_bibcite\"  bibcite=\"Pe90\"><a name=\"bibcite:11\"><\/a>[<a href=\"#ref-Pe90\">Pe90<\/a>]<\/span>.<\/p>\n<p>When we discuss &#8216;mind and body&#8217; we shall see a different view that places the human body as a crucial part of the picture, and some argue that no emulation of the mind could be truly a mind without being connected to a living, acting body.<\/p>\n<h2 class=\"touchit_heading\"><a name=\"sc:4.4\"><\/a><!-- link_id --><span class=\"touchit_label touchit_label_section\"><span class=\"label_counter\">4.4<\/span> <\/span> Multiple intelligences<\/h2>\n<p>We will discuss the particular ways we think about objects and about space later in this book, but it is interesting to note that there are specific ways in which we think about objects that are not the same as the way we think about space, and different again from the way we think about other people. We pick up objects, move them around, and expect that they may be moved by others or natural forces. In contrast, with space, buildings, and the topography of hills and mountains, we are thinking about moving ourselves around and within them.<\/p>\n<p>To some extent these can be seen as workings of the same sort of reasoning applied to different kinds of situation and indeed this is certainly the case for more logical thinking. However, there is strong evidence that we also have quite specialised ways of thinking about different aspects of the world, sometimes called &#8216;<span class=\"touchit_term\"  ix_rawcontent=\"multiple intelligences\">multiple intelligences<\/span>&#8216; <span class=\"touchit_bibcite\"  bibcite=\"Ga83;Ga93\"><a name=\"bibcite:12\"><\/a><a name=\"bibcite:13\"><\/a>[<a href=\"#ref-Ga83\">Ga83<\/a>;<a href=\"#ref-Ga93\">Ga93<\/a>]<\/span>. Some evidence for this comes from brain science, which shows there are specialised areas of the brain related to particular aspects of perceiving, thinking and acting (to the extent that these are separate!), and some evidence from experimental studies which show that effectively identical problems are solved differently if presented in ways which appeal to our different &#8216;intelligences&#8217;.<\/p>\n<p>Imagine a pack of cards, each with a letter on one side and a number on the other.

The reason for the &#8216;incorrect&#8217; answers is that we have a tendency to look for &#8216;confirming&#8217; evidence, so we look at the back of the &#8216;2&#8217;, even though if it were not a vowel it would not invalidate the rule. We also focus on the cards most similar to concepts mentioned in the question, namely the vowel and the even number.

However, there are a number of technologies that more directly connect computer to brain, bypassing our voluntary body movements and our normal senses.<\/p>\n<p>We have already seen one example of this, the implants into <span class=\"touchit_term\"  ix_as=\"Warwick, Kevin\" ix_rawcontent=\"Kevin Warwick&amp;#8217;s\">Kevin Warwick&#8217;s<\/span> arm nerves that enabled him to control devices and directly connect to his wife. It is normal to use these nerves to control muscle movement and bodily feelings. So in a way this <em>is<\/em> bodily interaction &#8212; just bypassing the actual body!<\/p>\n<p>With different technology one can even bypass the nerves and tap directly into the brain. This is often called &#8216;<span class=\"touchit_term\"  ix_rawcontent=\"brain&amp;#8211;computer interaction\">brain&#8211;computer interaction<\/span>&#8216;.<\/p>\n<p>We have discussed how different parts of the brain perform different functions. Brain scanners can reveal this, but are a little large for use in computer interfaces. However, simpler <span class=\"touchit_term\"  ix_rawcontent=\"EEG\">EEG<\/span> equipment can be used instead. EEG (electroencephalography) is used for medical diagnosis and involves placing large numbers of electrodes on the skull and measuring the electrical activity induced in the scalp by the corresponding activity within the brain due to the firing of <span class=\"touchit_term\"  ix_rawcontent=\"neurons\">neurons<\/span>. Clinical apparatus may involve many dozens of electrodes, but in computer interaction research useful information can also be obtained using just a small number, often fitted into a skull-cap.<\/p>\n<p>For many years EEG has been used in simple <span class=\"touchit_term\"  ix_rawcontent=\"bio-feedback\">bio-feedback<\/span> equipment, perhaps playing a different tone or projecting colours. In particular it is often used together with the detection of particular frequencies of activity (alpha and beta waves) associated with states of alertness or relaxation.\u00a0While we do not normally have conscious control over these states of the brain, once they are made visible or audible in some way, subjects can often learn to influence them.<\/p>\n<p>Bio-feedback is more about allowing the user to monitor their own body. However, if the outputs of EEG equipment are put into a machine learning algorithm, it is possible for the computer to recognise some of the user&#8217;s &#8216;thoughts&#8217;, though only from a small pre-chosen set. For example, there has been some success using apparatus of this kind to control an onscreen pointer by having subjects simply think about moving it one way or another. The recognition rate is still relatively poor, so this is not currently an option for day-to-day computing. For those patients with severe <span class=\"touchit_term\"  ix_as=\"disability\" ix_rawcontent=\"disabilities\">disabilities<\/span>, particularly those with &#8216;locked-in syndrome&#8217;, both non-invasive use of EEG (or similar apparatus) and direct <span class=\"touchit_term\"  ix_as=\"implanted\" ix_within=\"computers\" ix_rawcontent=\"\"><\/span><span class=\"touchit_term\"  ix_rawcontent=\"brain implants\">brain implants<\/span> offer a chance to be able to communicate with the world.<\/p>\n<p>There has also been some limited success in work with <span class=\"touchit_term\"  ix_rawcontent=\"brain implants\">brain implants<\/span> for visual impairment. Visual images are transferred from the retina to some parts of the visual cortex in a fairly direct way: there is something like (but not exactly like) a little image of the scene that you can see in front of you in the visual cortex. By working the other way round, brain implants that stimulate the visual cortex appear as points of light.<\/p>\n<p>Less invasive means can be used for more everyday interactions, especially in <span class=\"touchit_term\"  ix_as=\"affective\" ix_within=\"gaming\" ix_rawcontent=\"\"><\/span><span class=\"touchit_term\"  ix_rawcontent=\"affective gaming\">affective gaming<\/span>, that is games that respond in some way to the user&#8217;s emotional state. Most of these make use of heartbeat, or GSR (galvanic skin response &#8212; basically sweating as used in lie detectors). Both are related to the general level of arousal of the body, and so can be used as a rough measure of emotion. The most common form of game is &#8216;relax to win&#8217;, as you become more relaxed you get more speed or energy. This may be combined with social situations in which your friends try to make you less relaxed!<\/p>\n<p>These physiological measures tell you how strong an emotion is, but not whether the person is very happy, or very angry, nor do they detect subtle emotions such as apprehension. Typically, more detailed <span class=\"touchit_term\"  ix_as=\"detection\" ix_within=\"emotion\" ix_rawcontent=\"emotion detection\">emotion detection<\/span> needs to use facial expression or tone of voice, both of which are more complex yet still only deliver a fairly small palette of emotions. Kiel Gilleade&#8217;s research has tried to bridge this gap by using the fact that as humans we are successful (when we are!) at detecting other people&#8217;s emotions, because we also know the context <span class=\"touchit_bibcite\"  bibcite=\"GDA05\"><a name=\"bibcite:18\"><\/a>[<a href=\"#ref-GDA05\">GDA05<\/a>]<\/span>. In games one has a lot of information about the context, as it is a simulated world, and hence it is possible to make some inferences even from simple physiological measures.<\/p>\n<p>The trouble with attempting to ascertain brain state from body state is that the body is affected by many things as well as what you are thinking and feeling. A researcher at Bristol University, Cliff Randell, designed a small camera that he wore connected to a heart-rate monitor. He reasoned that the important events one might want to record would be marked by periods of heightened emotion, so a camera was triggered to take a photograph when his heart rate peaked. The technology worked in the lab, but when he wore it elsewhere he found the photos were full of the tops of flights of stairs.<\/p>\n<p>While the lacuna between pure mind and computation remains, it is perhaps not as wide as it once was. The means of contact are still very physical (silicon chips in the brain, wires and electrodes on the skull), but intimate and direct.<\/p>\n<h2 class=\"touchit_heading\"><a name=\"sc:4.6\"><\/a><!-- link_id --><span class=\"touchit_label touchit_label_section\"><span class=\"label_counter\">4.6<\/span> <\/span> Creativity and physicality<\/h2>\n<p><span class=\"touchit_term\"  ix_rawcontent=\"Creativity\">Creativity<\/span> is surely a defining cerebral activity. <span class=\"touchit_term\"  ix_rawcontent=\"Artists\">Artists<\/span> wait upon the inspiration of their muse and the results are translated into words, images or sound.

In a series of <span class=\"touchit_term\"  ix_as=\"experiments\" ix_within=\"psychology\" ix_rawcontent=\"experiments\">experiments<\/span> he studied simple problems where subjects were asked to perform simple creative tasks: creating things (e.g. means of transport) from shapes such as rods and circles. In some conditions the subjects were first given the shapes to play with for a period and then asked to come up with a design. In others they were simply presented with the shapes and immediately asked to come up with a design. He found that those who had time to play in a non-goal-directed way were able to produce more &#8216;creative&#8217; designs.<\/p>\n<p>This series of experiments by Finke and his colleagues was the basis of the &#8216;<span class=\"touchit_term\"  ix_rawcontent=\"geneplore\">geneplore<\/span>&#8216; model of creativity <span class=\"touchit_bibcite\"  bibcite=\"FW96\"><a name=\"bibcite:20\"><\/a>[<a href=\"#ref-FW96\">FW96<\/a>]<\/span>, which has two stages. The first is a &#8216;generation&#8217; phase (corresponding to the play), which is not directed towards the goal, during which the subjects develop &#8216;pre-inventive structures&#8217;, patterns and relations of the materials to be used. This is followed by an &#8216;exploration&#8217; stage (slightly confusingly named)\u00a0when the pre-inventive structures are put together to deliver the creative solution. While there have been criticisms of both the model and the methods, the work underlined the benefits of the use of physical materials (although interestingly people could also perform purely mental &#8216;play&#8217; as well).<\/p>\n<p>In our own observations of group design activities we have also seen some profound effects of the choice of <span class=\"touchit_term\"  ix_as=\"in design\" ix_within=\"materials\" ix_rawcontent=\"\"><\/span><span class=\"touchit_term\"  ix_rawcontent=\"design materials\">design materials<\/span> on the results obtained. As part of a workshop on the topic of Physicality, attendees were divided into small teams and given a design brief: &#8216;a hand-held device for producing light&#8217;. Each team was given one of three kits of design materials to use, either (a) paper and pencils, (b) card and glue, or (c) modelling clay (plasticine). Participants were only supposed to use their own materials (although some cheated!). Beyond this they were not told how to use the materials, but in fact the materials implicitly suggested ways of use. For example, no team in the paper and pencil group chose to fold or mould the paper to make a model. In normal design any or all of these materials would be used according to the preferences of the <span class=\"touchit_term\"  ix_as=\"designers\" ix_rawcontent=\"designer\">designer<\/span> at a particular moment.

And human ingenuity can conquer the obstinacy of the material world: one group made a cuddly teddy bear out of paper by tailoring the paper as one would a suit of clothes.<\/p>\n<div class=\"touchit_figure\"><a name=\"fg:4.8\"><\/a><!-- link_id --><a name=\"fg:match-puzzle-solution\" class=\"xref_label\"  xref_local=\"fg:match-puzzle-solution\" xref_label=\"fg:mind.match-puzzle-solution\"><\/a><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-2565\" src=\"https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/12\/matches-solution-300x204.png\" alt=\"\" width=\"250\" height=\"170\" srcset=\"https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/12\/matches-solution-300x204.png 300w, https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/12\/matches-solution-1024x697.png 1024w, https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/12\/matches-solution-400x272.png 400w, https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/12\/matches-solution-768x522.png 768w, https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/12\/matches-solution-1536x1045.png 1536w, https:\/\/physicality.org\/internal\/touchit-draft\/wp-content\/uploads\/2019\/12\/matches-solution.png 1689w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><\/p>\n<p><p class=\"touchit_caption\"><span class=\"touchit_label touchit_label_figure\"><span class=\"label_prefix\">Fig.<\/span> <span class=\"label_counter\">4.8<\/span> <\/span>   Solution to match puzzle in Figure <span class=\"touchit_xref\"   xref_label=\"fg:mind.match-puzzle\" xref_postid=\"89\" touchit_value=\"4.6\" touchit_type=\"figure\"><!-- xref_xshortcode_handler: name = fg:match-puzzle --><a name=\"xu:5\"><\/a><a href=\"#fg:match-puzzle\">4.6<\/a><!-- xref_data: Array\n(\n    [name] => fg:mind.match-puzzle\n    [postid] => 89\n    [slug] => fg:match-puzzle\n    [local] => fg:match-puzzle\n    [global] => fg:mind.match-puzzle\n    [value] => 4.6\n    [type] => figure\n    [content] => \n)\n   --><\/span> <\/p><\/p>\n<p><\/div>\n<h2 class=\"touchit_bibliography_heading\">References<\/h2>\n<div class=\"bibitem\"><p class=\"bibitem_inner\"><span class=\"bibitem-label\">1.
