Studies initiated in the 1990s of a patient with a rare condition affecting the amygdala initially seemed to support this conclusion. However, as Lisa Feldman Barrett, Ph.D., of the Massachusetts General Hospital (MGH)

Researchers at the RIKEN Center for Brain Science have discovered a circuit in the brain that is necessary for unlearning fear. Published in Nature Communications, the study details the role of dopamine in ensuring that rats lose fear response in the prolonged absence of the stimulus. Like animals, people develop conditioned responses, especially if strong

Innate fear is an essential emotion for animals to avoid danger in a severe natural environment.
