Cerebral Cortex Shape Correlated With Genetic Ancestry

The three-dimensional shape of the cerebral cortex, the wrinkled outer layer of the brain controlling many functions of thinking and sensation, strongly correlates with ancestral background, researchers at the University of California, San Diego have found. The study could lead to more precise studies of brain anatomy going forward, and could eventually open the door […]

Prion-like Proteins Maintain Long-term Memories

More evidence of a system in the brain that maintains memories for long periods of time has been found by Columbia University Medical Center researchers. Intriguingly, it functions similar to the mechanisms that cause mad cow disease, kuru, Creutzfeld-Jakob disease, and other degenerative brain diseases. In the work, Dr. Eric Kandel shows how prion-like proteins […]

Depression Damages Parts Of The Brain, Research Concludes

Brain damage is caused by persistent depression rather than being a predisposing factor for it, researchers have finally concluded after decades of unconfirmed hypothesising. A study published in Molecular Psychiatry today has proved once and for all that recurrent depression shrinks the hippocampus – an area of the brain responsible for forming new memories – […]

Are Emotional Brains Biologically Different From Rational Brains?

Physical differences in the brains of people who respond emotionally to others’ feelings, compared to those who respond more rationally, have been found by researchers at Monash University. Led by Robert Eres from the University’s School of Psychological Sciences, the work pinpoints correlations between grey matter density and cognitive and affective empathy. The study investigated […]

How Does The Brain Recognize Faces From Minimal Information?

How does your brain recognize objects within milliseconds, even if it only gets rudimentary visual information? Researchers believe that reliable and fast recognition works because the brain is constantly making predictions about objects in the field of view and is comparing these with incoming information. Only if mismatches occur in this process do higher areas […]
