The brain relies on a tight rhythm of sleep-wake cycles and memory consolidation routines. When stress activates CRH neurons ...

The hypothalamus is a small but crucial part of the brain. It controls functions such as sleep and growth. View a 3-D diagram and learn about related conditions.

Stress worsens sleep quality and can impair memory. Shinjae Chung, from the University of Pennsylvania, led a study to ...

Both are primarily found in the hypothalamus—or more precisely, in the paraventricular nucleus, a core region of the hypothalamus—and have opposite actions. POMC neurons inhibit food intake ...

Within the hypothalamus lies the suprachiasmatic nucleus (SCN), which regulates sleep and wake cycles. ... which leads to the activation of the paraventricular nucleus.

The hypothalamus is subdivided into interconnecting nuclei, including the arcuate nucleus (ARC), paraventricular nucleus (PVN), ventromedial nucleus (VMN), dorsomedial nucleus (DMN) and lateral ...

But boredom isn't the only yawn factor. If someone you're conversing with yawns, chances are, you will too. "Yawning is extraordinarily contagious," says Robert Provine, a pioneer of yawning research.

The hypothalamic paraventricular nucleus (PVN), an integrating site in the regulation of neuroendocrine and autonomic nervous systems, is composed of heterogeneous neurons, type I and type II, based ...
