Optogenetic stimulation of the perirhinal cortex can cause macaques to process never-before seen-objects as familiar and known objects as brand new.

In tissue samples from rhesus macaques, researchers find the virus in the same immune-privileged sites where Ebola has been found to persist in humans.

Anatomical analysis suggests monkeys possess all the hardware for human-like speech, they just lack the neurological capacity to use it.

Scientists image fetal brain lesions in a pigtail macaque whose mother was infected with the virus while pregnant.

The brains of primates and mice follow the same exponential rule of connectivity, according to a study.
