Looks like ~10% (maybe a bit more) of the brain, right? P.L. mentioned that this might be the basis of the "we only use 10% of our brain" myth. The popular (and incorrect) interpretation of Lashley's work (see yesterday's post) was that only the primary sensory-motor regions are necessary. This is not true in the least. Association cortex is the seat of most cognition, and we would not be ourselves without it. By the way, notice the primary sensory-motor cortices in the post’s figure.
