Inteligence can roughly be pegged to an increase in surface area on the brain. Smaller brains tend to have more folds, and hence smaller brains may
on average have more surface area. The folds are more important than the outer dimensions when looking for inteligence.
Dolphins are a good example of this. They have a medium sized brain, but it has pronounced folds and is very dense. Bottle nosed Dolphins at least
(I presume the same is true of most or all other species) are able to use a greater portion of their brain than we can, probably due to the depth of
the folds in our respective grey matter. Dolphins have a brain with exceedingly deep channels, and a tight, interknitted structure. On top of that,
their brain is split farther down the middle than ours, almost to the base. That's a ton of extra surface area, on top of the density in their
A large brain with the same number of folds as a small brain would be much smarter, it would have more surface area on which to store data, and more
connections possible meaning a greater depth of inteligence. An enormous brain with the correct sensors could accurately predict the future, even our
modern Brain: V.Beta can sometimes do it.
Even though the number of connections grows larger in big brains, perhaps the transfer time, or thinking speed decreases? If the brain's software
has to index a much larger set of folders, it might not have the same agility when comparing ideas and searching for data.
I'm just happy I have a big brain that works at all, whether or not my folds are dense.
