The amygdala is important for the generation, perception, and aversion learning of negative emotions.

The amygdala, also known as the amygdala, is almond-shaped and is part of the limbic system. It is the brain tissue that generates emotions, identifies emotions and regulates emotions, and controls learning and memory. Studies have found that autism in young children also seems to be related to the enlarged amygdala.

The amygdala, also known as the amygdaloid body, is located in the dorsomedial part of the anterior temporal lobe, slightly anterior to the hippocampus and the top of the inferior horn of the lateral ventricle.

Mainly through the lateral olfactory stria, stria terminalis and ventral amygdala efferent pathways, it communicates with the medial frontal lobe, orbitofrontal gyrus, septal area, substantia innominata, preoptic area, hippocampus, hypothalamus, thalamus, There are two-way interactive connections between the striatum, temporal cortex, insular cortex, parietal cortex, temporal pole, motor cortex and brainstem reticular formation.

The amygdala is an important nucleus in the basal ganglia of the brain. It is a component of the limbic system and contains 13 nuclei of varying sizes. According to its location and function, it is divided into 4 parts: the basolateral nucleus group, the cortical medial nucleus group, the preamygyloid area and the cortical amygdala transition area.

The afferent fibers of the amygdala mainly originate from the cholinergic neurons of the olfactory bulb and preolfactory nucleus, Meynert nucleus of the basal forebrain, brainstem, interpeduncular nucleus of the midbrain, parabrachial nucleus, and pontine orchids. macula, midbrain raphe nucleus and ventral dorsal operculum, ventromedial nucleus of the hypothalamus, thalamic midline nucleus group and ventromedial nucleus of the thalamus, etc.
