Do Apes Have Corpus Callosum?

Post hoc analysis indicated that chimpanzees had relatively larger corpus callosi for all five regions compared to capuchins. Within the chimpanzees, the relative size of the genu and splenium was significantly larger than the rostral, central and posterior mid-bodies.

Do animals have a corpus callosum?

All placental mammals have a corpus callosum, but for some reason, the other two main groups of mammals do not. Instead of a corpus callosum, marsupials (pouched mammals) and monotremes (egg laying mammals) have a simple network of nerve fibers that connect their brain hemispheres.

How is the corpus callosum in humans different from other primates?

The corpus callosum size is relatively smaller in humans than in other primates. ... The splenium scales at a higher exponent of allometry than other callosal regions, perhaps reflecting the need to preserve integration of left and right visual hemifields with increasing brain size.
