Neural circuitry for innate fear
Innate fear is a kind of inherited fear of specific objects, environment or situation without learning. For example, rodents are fear of cats by nature. Even native mice will express fear response in the present of a cat. This emotion trigged by a perceived threat usually causes a quick response, such as freezing, flee or hide, and thus has a profound role for survival and health for all species. Abnormal innate fear in humans particularly phobias and panic disorders is highly associated with anxiety disorder. Recent studies suggested that innate fear induced by different cues were attributed by distinctive neural circuits. Vision and auditory cues, but not olfactory cue induced innate fear is related amygdala. So far, which parts of the brain are involved in olfactory cue induced innate fear remains unclear. We will combine electrophysiological, immunohistochemical, optogenetics and animal behavioral assays to explore the neural circuit for odor induced innate fear.
