Fear is essential to an individual's survival. Abnormal fear will make people or animals more vulnerable to danger, and even lead to a series of neuropsychiatric diseases. Previous studies have suggested that functional abnormalities of the ventral tegmental area (VTA) may lead to fear-related neuropsychiatric diseases, such as post-traumatic stress disorder and schizophrenia, but the underlying mechanisms remain unclear.
