In depression the brain region for stress control is larger

Although depression is one of the leading psychiatric disorders in Germany, its cause remains unclear. A recent study at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig, Germany, found ...

Nature or nurture? Innate social behaviors in the mouse brain

Adult male mice have a simple repertoire of innate, or instinctive, social behaviors: When encountering a female, a male mouse will try to mate with it, and when encountering another male, the mouse will attack. The animals ...

Obese inducing brain mechanism

Leptin is an adipocyte-derived hormone that stimulates hypothalamic neurons to strongly inhibit food intake. Leptin signaling in the hypothalamus, a part of the mid-brain, thus plays a crucial role in the regulation of body ...

Manipulating a single gene defines a new pathway to anxiety

Removing a single gene from the brains of mice and zebrafish causes these animals to become more anxious than normal. Researchers from University of Utah Health show that eliminating the gene encoding Lef1 disrupts the development ...

Brain cells found to control aging

Scientists at Albert Einstein College of Medicine have found that stem cells in the brain's hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related ...

Brain's immune cells may drive overeating and weight gain

Immune cells in the brain trigger overeating and weight gain in response to diets rich in fat, according to a new study in mice led by researchers from UC San Francisco and the University of Washington Medical Center, and ...

Hypothalamus neurons modulate pancreatic insulin amounts

The brain is key in the regulation of appetite, body weight and metabolism. Specifically, there is a small group of POMC neurons in the hypothalamus that detect and integrate signals related to the body's energy state and ...

Research identifies brain cells that keep mice active

Scientists have discovered a type of brain cell that prevents mice from being overly immobile. The research provides insight into the brain circuits underlying what motivates us to be physically active.

Gamma oscillations coordinate food seeking

Food seeking is a crucial survival instinct. However, until recently, little was known about how the brain regulates this behavior. Scientists at the Leibniz-Institut für Molekulare Pharmakologie (FMP) and NeuroCure Cluster ...

Hypothalamus

The hypothalamus is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis). The hypothalamus, (from Greek ὑποθαλαμος = under the thalamus) is located below the thalamus, just above the brain stem. In the terminology of neuroanatomy, it forms the ventral part of the diencephalon. All vertebrate brains contain a hypothalamus. In humans, it is roughly the size of an almond.

The hypothalamus is responsible for certain metabolic processes and other activities of the Autonomic Nervous System. It synthesizes and secretes neurohormones, often called hypothalamic-releasing hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones. The hypothalamus controls body temperature, hunger, thirst, fatigue, and circadian cycles.
