External Email - Use Caution Hi Maedeh,
The human cerebral cortex is a highly folded sheet of neurons the thickness of which varies between 1 and 4.5 mm, with an overall average of approximately 2.5 mm (1–3). Regional variations in the cortical thickness can be quite large. For example, Brodmann’s area 3 on the posterior bank of the central sulcus is among the thinnest of cortical regions, with an average thickness of less than 2 mm, whereas Brodmann’s area 4 on the anterior bank is one of the thickest regions, frequently exceeding 4 mm. Interestingly, the distribution of the thickness is not uniform by layer, nor is the variation in the thickness of the cortical layers proportional to the variation in the total thickness.
