Evolution may have given humans unique brain structures, say scientists

Brain structures that are unique in humans are anatomically missing in Rhesus monkeys.

Has evolution given humans unique brain structures? For years, scientists have been asking themselves this question. Now, scientists from the University of Leuven have the first piece of evidence that could prove that humans have unique cortical brain networks. The study’s findings were published in The Journal of Neuroscience.

The scientists examined functional brain scans in humans and rhesus monkeys at rest and while watching a movie to compare both the location and the function of cortical brain networks. They report that even at rest, the brain is extremely active. Varying brain areas that are active simultaneously during rest create “resting state” networks.
