Scientists erased anxiety in mice by tuning a single gene in one cluster of amygdala neurons, then watched normal social behavior return
Researchers reversed anxiety, depression-like behavior, and social withdrawal in mice by correcting the dosage of a single ...
Fear is an adaptive emotion that helps us cope with threatening situations. Deep within the temporal lobe of the brain is the amygdala, the most studied brain area involved in fear. The amygdala uses ...
Researchers are pioneering an innovative brain study that sheds light on how the amygdala portion of the brain functions and could contribute to a better understanding of post-traumatic stress ...
A Dartmouth study challenges the conventional view that the amygdala-the two-sided structure deep in the brain involved in emotion, learning, and decision making-is simply the brain's primitive "fear ...
