<p>Many of us own computers, and we (well, most of us) have a rough
idea that computers are
made up of complicated hardware and software. But perhaps few of us
know that the concept of a computer was envisioned long before these
machines became ubiquitous items in our homes, offices and even
pockets. And as we will see later, some have even suggested that our
own brains are embodiments of this theoretical concept.

<p>Geometric hallucinations are very common: people get them after taking drugs, following sensory deprivation, or even after rubbing their eyes. What can they tell us about how our brain works?</p>

<p>Think drug-induced hallucinations, and the whirly, spirally, tunnel-vision-like patterns of psychedelic imagery immediately spring to mind. But it's not just hallucinogenic drugs like LSD, cannabis or mescaline that conjure up these geometric structures.<p><a href="http://plus.maths.org/content/how-do-we-hallucinate" target="_blank">read more</a></p>http://plus.maths.org/content/how-do-we-hallucinate#commentsAlan Turingmathematical modellingmedicine and healthmorphogenesisneuroscienceFri, 24 Jan 2014 10:54:47 +0000mf3446029 at http://plus.maths.org/contentCognition, brains and Riemann

<p>Are number, space and time features of the outside world or a result of the brain circuitry we have developed to live in it? Some interesting parallels between modern neuroscience and the mathematics of 19th century mathematician Bernard Riemann.</p>
</div>

<p><em>Modern neuroscience suggests that number, space and time aren't so much features of the outside world but more a result of the brain circuitry we evolved to move around in it. And this circuitry is all about judging less than/greater than relationships. In the 19th century the mathematician Bernard Riemann suggested that the mathematical ideas of space, quantity and measure should not depend on the outside world, but defined abstractly and in relation to each other. Joselle DiNunzio Kehoe finds some interesting parallels between these two ideas.</em></p><p><a href="http://plus.maths.org/content/cognition-brains-and-riemann" target="_blank">read more</a></p>http://plus.maths.org/content/cognition-brains-and-riemann#commentsmathematical realityneurosciencephilosophyphilosophy of mathematicspsychologyTue, 09 Jul 2013 05:29:55 +0000mf3445915 at http://plus.maths.org/contentNeuro-tweets: #hashtagging the brain

<p>We like to think of the human brain as special, but as we reported on <em>Plus</em> last year, it has quite a lot in common with worm brains and even with high-performance information processing systems. But how does it compare to online social networks? In a recent lecture the psychiatrist Ed Bullmore put this question to the test.</p>

The human brain faces a
difficult trade-off. On the one hand it needs to be complex to ensure high performance, and on the other it needs to minimise "wiring cost" — the sum of the length of all the connections —
because communication over distance takes a lot of energy. It's a problem well-known to computer scientists. And it seems that market driven human invention and natural selection have come up with similar solutions. </div>
