2-Minute Neuroscience: Hypothalamus

The hypothalamus is a complex structure that contains more than a dozen nuclei with different functional specializations. It is involved in a long list of processes, many of which are critically important to maintaining homeostasis across various bodily systems. In this video, I discuss the anatomy and function of the hypothalamus. Learn more on my website: https://neuroscientificallychallenged...

It sits above and is connected to the pituitary gland, a neuroendocrine gland whose function is regulated by the hypothalamus. The hypothalamus is a complex structure that contains more than a dozen nuclei with different functional specializations. It is involved in a long list of processes, many of which are critically important to maintaining homeostasis across various bodily systems. The hypothalamus receives information from the body and other parts of the nervous system about a range of physiological parameters, and it can influence behavioral systems, the autonomic nervous system, and neuroendocrine systems, to initiate mechanisms to restore homeostasis when needed. Some of the major functions generally attributed to the hypothalamus include the regulation of: thirst and drinking behavior, fluid and electrolyte balance, hunger and feeding, body temperature, stress responses, aggressive behaviors, reproductive behaviors, circadian rhythms, the sleep-wake cycle, and more. One common method of anatomically subdividing the hypothalamus is from front to back into thirds. The frontmost region of the hypothalamus is called the preoptic area, and it includes nuclei that play critical roles in the regulation of body temperature, fever, electrolyte balance, circadian rhythms, sexual behavior, and more. The middle region is called the tuberal hypothalamus. A structure called the infundibulum, or pituitary stalk, emerges from the tuberal hypothalamus and connects the hypothalamus to the pituitary gland. The nuclei in the tuberal region play roles in hunger and feeding, sexual behavior, aggressiveness, and a number of autonomic and endocrine responses, among other things. The posterior region contains nuclei involved in wakefulness, stress responses, memory, and other functions. REFERENCES Fong H, Zheng J, Kurrasch D.
