The other areas of the  brain, as in all other animals with brains, have to do with running the bodies motion. picking up incoming sensations, stimulating reproduction. The reduction  from new uses was also frontal lobe dealing with abstractive thought. The hippocampus grew.

And I have been telling you for months that it shrunk because the efficiency of enhanced complexification made certain cells redundant – in direct contrast to your constantly repeated claim that the new cells were redundant from the start and those same cells were discarded later.

> We don't know which  were mew cells and don't know if they were the ones discarded. Excess cells were available for use from the beginning of the sapiens brain. That is my key point. Since complexification got rid of 150 cc of cells, old or new is of no matter.
