The anterior hypothalamic nucleus is a collection of neurons located in the rostral region of the hypothalamus, involved in regulating various autonomic functions such as body temperature, hunger, thirst, and circadian rhythms, as well as emotional behaviors.

The dorsomedial hypothalamic nucleus (DMH) is a key region in the hypothalamus of the brain that is involved in various functions such as regulation of energy balance, body temperature, food intake, and autonomic and neuroendocrine responses.

The ventromedial hypothalamic nucleus (VMH) is a critical region in the hypothalamus of the brain that plays a significant role in regulating various essential physiological functions, including feeding behavior, energy balance, and autonomic responses, through complex interactions with other neural circuits and hormonal signals.
