Neuroscience fiction

Feeling a bit end-of-winter fuzzy? Awash with Wednesday ennui? Fed up with days filled with frustration, procrastination and possibilities that never quite manifest?

Then read this.

Your brain is built of cells called neurons and glia—hundreds of billions of them. Each one of these cells is as complicated as a city. Each cell contains the entire human genome and traffics billions of molecules in intricate economies. Each cell sends electrical pulses to other cells, up to hundreds of times per second. If you represented each of these trillions and trillions of pulses in your brain by a single photon of light, the sum total would be blinding.

The cells are connected to one another in a network of such staggering complexity that it bankrupts human language and necessitates new kinds of mathematics. A typical neuron makes about 10,000 connections to neighboring neurons, which means that there are more connections in a few cubic centimeters of brain tissue than there are stars in the Milky Way galaxy.

The three pound organ in your skull—with its pink consistency of jello—is an alien kind of computational material. It is composed of miniaturized, self-configuring parts, and it vastly outstrips anything we’ve dreamt of building. So if you ever feel lazy or dull, take heart: you’re the busiest, brightest thing on the planet.

Now tell me you don’t feel a little more, well, special? It is from Incognito: The Secret Lives of the Brain, the new book by neuroscientist David Eagleman, who delivered a fantastic lecture at the Southbank Centre this week and who is indisputably the Brian Cox of the brain (with added humour and a better haircut). Here he is talking about possibilianism at PopTech last year (possibly).

I – like anyone who has suffered from mental health issues, delusions and addictions (which is pretty much all of us, to differing degrees) – have had to engage at close quarters with the alien machinery inside my skull. The past decade has been a battle, sometimes a distinctly bloody one, to mediate the fractious rivals inside this soggy pink parliament and channel its hungry, impulsive power into moderate and productive pathways. With each small, slow success I have moved a little further from fear to fascination, until now, with the help of people like Eagleman, I am in an almost obsessive state of grateful, curious wonder about how I act out ‘I’ every day.
