Hypothalamus and Thalamus Overview

Maintains homeostasis by regulating thirst, water balance, hormone release (anterior and posterior pituitary), hunger, autonomic nervous system, temperature, and sexual urges.

Regulates hunger, stimulated by ghrelin, inhibited by leptin.

Regulates satiety (feeling full).

Major relay center for ascending sensory information (except olfaction).

Relays sensory information for touch, temperature, pain, and body position.

The hypothalamus regulates homeostasis by controlling functions such as thirst, water balance, hormone release, hunger, temperature, and sexual urges. It also acts as a bridge between the nervous and endocrine systems.

The Lateral Nucleus controls feelings of hunger. It is stimulated by ghrelin (hunger hormone) and inhibited by leptin (satiety hormone).

Damage to the Ventromedial Nucleus leads to hyperphagia, which means excessive eating.

The Thalamus acts as a major relay center for all sensory information except smell. It forwards sensory signals to the appropriate regions of the cerebral cortex for processing.

The VPL Nucleus receives sensory input from the body about touch, pain, temperature, and position. It then relays this information to the primary somatosensory cortex for interpretation.

The lateral nucleus in the hypothalamus is responsible for regulating hunger. It's stimulated by the hunger hormone ghrelin and inhibited by the satiety hormone leptin.

The ventromedial nucleus regulates satiety, or feeling full, after eating. Its stimulation by leptin signals the brain to stop eating.

The thalamus acts as a relay station for all sensory information (except smell) traveling to the cerebral cortex for processing.

The Ventral Posterolateral (VPL) nucleus receives sensory input from the body about touch, pain, temperature, and body position, and relays it to the somatosensory cortex.

The hypothalamus is a brain region that maintains a stable internal environment by regulating body temperature, hunger, thirst, and hormone release.

The Ventral Posterolateral (VPL) nucleus in the thalamus receives sensory information from the body about touch, temperature, pain, and body position.

The ventromedial nucleus helps you feel full and stop eating. It's stimulated by leptin, the satiety hormone.

The Ventral Posterolateral (VPL) nucleus receives sensory information from the body about touch, temperature, pain, and body position, and relays it to the somatosensory cortex.

The VPL nucleus in the thalamus receives sensory information from the body about touch, pain, temperature, and body position. It then relays this information to the primary somatosensory cortex.
