Researchers at The University of Texas at San Antonio (UTSA) are pioneering an innovative brain study that sheds light on how the amygdala functions and could contribute to a better understanding of post-traumatic stress disorder, anxiety, depression, and Alzheimer’s disease. “This novel research paper provides anatomical and physiological evidence for the existence of a long-range… Read more

Joseph LeDoux, in a new interview in Nautilus magazine, explains why it’s wrong to call the amygdala the brain’s fear circuit: “The amygdala is a small region in the temporal lobe. We say “the amygdala,” but there are two amygdalas. Amygdalae. Traditionally it’s thought of as the fear center, an idea for which I’m partly… Read more

Selective release of the neurotransmitter noradrenaline reconfigures communication between large-scale networks in the brain, researchers at ETH Zurich have shown for the first time. The findings bring insight into speedy neural processes that happen in the brain in stressful situations. In moments of acute stress — for example, a life-threatening situation in road traffic —… Read more

Overnight amygdala adaptation fails proportionally to the restlessness of REM sleep, new research from the Netherlands Institute for Neuroscience suggests. The finding helps explain why you will be better able to bear tomorrow what you are distressed about today, and why that can go wrong. Something frightening or unpleasant does not go unnoticed. In our… Read more

Providing “targeted” social support to other people in need activates regions of the brain involved in parental care, a new study indicates. The findings may help researchers understand the positive health effects of social ties. By comparison, providing “untargeted” support such as giving to charity does not have the same neurobiological effects, according to the… Read more
