Schoenemann et al. reply:

Sherwood et al. find the prefrontal volume proxy we used problematic, even though it has been widely used in the neuropsychological literature for many years1,2,3,4, and it (or variants) have also been applied to non-human primates5,6. Sherwood et al. believe this proxy specifically underestimates the size of ape values, yet the frontispiece of one of the sources they cite7 clearly shows any underestimation is minor compared to that found in humans. Taking refs. 7 and 8 together, we see that the degree of underestimation using this method increases as one gets closer to humans. An image highlighting the approximate degree of underestimation based on cytoarchitectural maps7,8 is posted on our web site, so interested readers may judge for themselves (http://www.sas.upenn.edu/~ptschoen/Pics/prefrontal-delineation.jpg).
