Neuroscience News Update

University of Georgia researchers have developed a map of the human brain that shows great promise as a new guide to the inner workings of the body’s most complex and critical organ.

Brains that maintain healthy nerve connections as we age help keep us sharp in later life, new research funded by the charity Age UK has found.

The brain reward systems of women with anorexia may work differently from those of women who are obese, a new study suggests.

Emotional stress caused by last year’s tsunami caused a part of some survivors’ brains to shrink, according to scientists in Japan who grasped a unique chance to study the neurological effects of trauma. On a quest to better understand post-traumatic stress disorder (PTSD), the researchers compared brain scans they had taken of 42 healthy adolescents in other studies in the two years before the killer wave, with new images taken three to four months thereafter. Among those with PTSD symptoms, they found a shrinking in the orbitofrontal cortex, a part of the brain involved in decision-making and the regulation of emotion, said a study published in the Nature journal Molecular Psychiatry.
