Technically, it’s 1) surface area (cortical volume) 3) number of neural colums 4) neural number and density, 5) and there is a minimum tolerable distance between neural columns. 5) it appears we obtained memory recursion and prediction vs chimp persistence, and this is probably the best explanation of intelligence (which teh AI discipline is rapidly beginning to understand at the moment): parallelism(disambiguation), prediction (association), and recursion (wayfinding).
