I was reading the Selfish Gene and I got to the part where the autor says that the human brain stores data much more efficiently and has a much more complex retrieval mechanism of memories than a computer counterpart. If storage and access are the goals, wouldn’t a “smooth” brain make more sense?
In: Biology
A brain stores information through the reinforcing of relationships between neurones. What’s important in this is the points those neurones interact, but that’s not what all of the brain is. For some unknown reason, grey matter – the part of the brain where the interactions happen – is only found on the surface of the cortex, while the insides are just the long thin bits (axons) of neurones relaying information to and from the grey matter. So, since the processing bit only occurs at the surface, the more surface you have, the more processing you can have, and the only interior space you’re losing when you fold like this is white matter space, which isn’t a problem cos you can just make the axons shorter.
