American scientists believe the formation of some fears is not determined by education or child development. Fear can be placed at the genetic level and be inherited.
The data were confirmed in experiments on laboratory mice. Scientists have divided the animals into two groups. In the first group of experts has developed fear in rodents smell of mint. The second group was the control. Scientists were able to localize the fear in the amygdala body brain. This structure is responsible for the process of recognition of the threats from the external environment.
Fear of the scent of mint was formed not only in adults but also in their offspring. If the experts gave the mice a drug that blocks the work of the amygdala, fear immediately disappeared.
