We choose the term 'isocortex' to refer to cerebral cortex in this conjecture, because it underscores the architectonic similarity of all areas of the cerebrum, as opposed to the more common term 'neocortex', which underscores the evolutionary recency of the cerebrum, which does not interest us.
A comparison of neurotransmitter-specific and neuropeptide-specific neuronal cell types present in the dorsal cortex in turtles with those present in the isocortex in mammals: implications for the evolution of isocortex.
This area corresponds to the posterior part of the frontal lobe (Brodmann's area 4, the primary motor field of the isocortex) and the anterior parts of the cerebral parietal lobe (the gyrus postcentralis, which corresponds to the primary somatosensory fields, Brodmann's areas 1, 2, and 3).
