Noradrenaline Reconfigures Functional Brain Connections During Stress

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 — […]

REM Sleep Quiets The Brain’s Warning Bells

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 […]

Providing Social Support Associated With Reduced Amygdala Activity

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 […]

Aversion-Reward Response In The Bed Nucleus Of Stria Terminalis

Connections between neurons in brain systems associated with reward, stress, and emotion have been identified in a new study. Conducted in mice, the study may help untangle multiple psychiatric conditions, including alcohol use disorder, anxiety disorders, insomnia, and depression in humans. “Understanding these intricate brain systems will be critical for developing diagnostic and therapeutic tools […]
