TABLE 8 
Giving for several localities on the hemisphere of the adult human brain the thick- 
ness of the cortex, as measured by different authors. The general average thick- 
ness was taken, averaging all measurements presented by each author. For 
reasons given in the text, these averages as they stand are by no means compara- 
ble with each other. The data were taken from Donaldson (’91), Hammarberg 
(95), Campbell ('05), and Brodmann (’08)
