The basal nucleus should be called the basal ganglia, also known as the basal ganglia, is a functional whole composed of a series of gray matter nuclei in the deep white matter of the brain. From an anatomical point of view, it mainly consists of four major parts: caudate nucleus, bean nucleus, screen nucleus and amygdala complex, whose main function is to control voluntary movements and participate in higher cognitive functions such as emotion, memory, reward and learning. The caudate nucleus, which is horseshoe-shaped in appearance, is a component of the striatum and consists mainly of small spindle-shaped or round nerve cells. The nucleus accumbens is a flattened gray matter located between the external capsule and the external capsule of the brain, which separates the nucleus accumbens from the nucleus pulposus, and the external capsule separates the nucleus accumbens from the insula, and plays an important role in the generation of consciousness. nuclei, which mainly form the superior and medial walls of the inferior horn of the lateral ventricles, are the brain tissues that control learning and memory, as well as generating, identifying and regulating emotions. Related studies have found a link between autism in young children and the amygdala complex.
