Interesting Science Pictures: Part X

Fig. 4. Comparison of evolutionary and postnatal cortical surface expansion. (A) Map of regional evolutionary cortical expansion between an adult macaque and the average human adult PALS-B12 atlas (right hemisphere only). Evolution expansion scale indicates how many times larger the surface area is in humans relative to the corresponding area in the macaque. (B) Map of human postnatal cortical expansion (combined left and right hemispheres) for comparison (detailed in Fig. 1 legend). (C) Correlation map comparing postnatal to evolutionary cortical surface expansion.

  1. Shiny!

  2. Interesting to be sure, but it always makes me wary when the “monkey” is used as the hypothetical ancestral condition for human evolution, especially the brain.
