The five major centers of the nervous system for the hypothalamus (within the blood sugar homeostasis center, water balance center, thermoregulation center, etc.), the brainstem (within the cardiovascular motor center, respiratory center, etc.), the cerebral cortex (within the somatomotor center, language center, etc.), cerebellum (within the somatomotor homeostasis center), the spinal cord (within the knee-jerk reflex, blinking reflex, shrinking reflex, sucking and urination reflexes in infants, and other activities of the low-level centers). (lower centers). The higher functions of the human brain include language, learning, memory and thinking.

So the answer is:

Hypothalamus? cerebral cortex? Language.
