Differences Between Brains

Now that body size and brain size are out of the equation, are there any differences between all these brains?

It seems that there are still structural differences that are quite apparent in all these brains.

human brain Some brains seem to have more grooves and indentations in the cortex than others. squirrel brain
camel brain Some brains seem to have larger or more noticeable structures than others. monkey brain
squirrel brain Some brains of animals which we assume would be similar actually look quite different (for example, a squirrel, left, and a rabbit, right). rabbit brain

So, in other words, although we've made all the brains equal in size, there still seem to be some differences that have nothing to do with size. This leads us to a question: are intelligence and behavioral complexity more related to brain size or to some kind of structural difference within the brain? Why don't we look closer and find out?

Do you want to look closer into these brains and examine various structures? Or do you want to look at intelligence issues?
