Latest Hypothalamus Stories
An in vivo study shows for the first time that there is a stress-response system within the cochlea that mirrors the signaling pathways of the body's fight or flight response.
The constant stress that many are exposed to in our modern society may be taking a heavy toll: Anxiety disorders and depression, as well as metabolic (substance exchange) disorders, including obesity, type 2 diabetes and arteriosclerosis, have all been linked to stress.
Until now there were only indirect evidence of the transfer of thyroid hormones from mother to fetus through the placenta during pregnancy.
New findings by UT Southwestern Medical Center researchers suggest that the hormones leptin and insulin work together in specific neurons in the hypothalamus region of the brain to affect both the regulation of blood sugar levels in the body and, surprisingly, female fertility.
Bad behavior in childhood is associated with long-term, chronic widespread pain in adult life, according to the findings of a study following nearly 20,000 people from birth in 1958 to the present day.
In their latest study, researchers at the Salk Institute for Biological Studies describe how, depending on the nature of the stimulus, resident macrophages lined up along the blood-brain barrier play opposing roles in the transmission of immune signals into the brain.
Previous work in birds and sheep shows a wealth of clinical possibilities.
Persons with higher levels of leptin, a protein hormone produced by fat cells and involved in the regulation of appetite, may have an associated reduced incidence of Alzheimer disease and dementia, according to a study in the December 16 issue of JAMA.
Even the anticipation of sweets may cause our muscles to start taking up more blood sugar, say researchers reporting in the December issue of Cell Metabolism, a Cell Press publication.
Contrary to the prevailing view, the hormone leptin, which is critical for normal food intake and metabolism, appears to regulate bone mass and suppress appetite by acting mainly through serotonin pathways in the brain.
The hypothalamus is an organ that serves as an important link, along the hypothalamic-hypophyseal axis, between the nervous system and the endocrine system. It is located within the cranial cavity, in the cerebrum, right below the thalamus. It also forms the floor of the third ventricle in the brain. It contains neural pathways, blood vessels, glial cells, and secretory cells—all of which work together to control things like body temperature, hunger, thirst, sleep, and hormonal and...
