And according to the Mayo Clinic, people who are dying of cold usually don’t realize it. As sleet, snow or cold rainfall is expected in metro Atlanta on Friday amid freezing temperatures, Southerners who...

Stimulating hypothalamus restores walking in paralyzed patients
Peer-Reviewed Publication Ecole Polytechnique Fédérale de Lausanne Researchers at EPFL and Lausanne University Hospital (CHUV), led by professors Grégoire Courtine and Jocelyne Bloch, have achieved a major milestone in the treatment of spinal cord injuries (SCI). By applying deep brain stimulation (DBS) to an unexpected region in the brain—the lateral hypothalamus (LH)—the team has improved the recovery of lower limb movements in...

Expression pattern of key receptors in the hypothalamus revealed
by Susann-C. Ruprecht, Deutsches Institut für Ernährungsforschung Potsdam-Rehbrücke Brain slices of the mouse are placed onto a glass slide, for further imaging. Credit: David AusserhoferThere is growing evidence that peptide hormones from the gut have far-reaching effects on the whole organism. By binding to corresponding receptors in the brain, they can modulate food intake and...

Researchers use model of hypothalamus to implicate genes associated with sleep, BMI, puberty, and more
by Children’s Hospital of Philadelphia Credit: Pixabay/CC0 Public Domain A study led by researchers at Children’s Hospital of Philadelphia (CHOP) has implicated several genes involved in a variety of bodily functions associated with the hypothalamus, a notoriously difficult-to-study region of the brain. The findings could help clinicians identify potential causes of dysfunction for many important traits...

REM sleep tunes eating behaviour
by University of Bern Using a technique called optogenetics, the activity of cells in the brain can be specifically suppressed with light pulses. Credit: Pascal Gugler / Insel Gruppe Despite our broad understanding of the different brain regions activated during rapid-eye-movement sleep, little is known about what this activity serves for. Researchers at the University...

How fear transforms into anxiety
by University of New Mexico A deadly coronavirus pandemic, economic instability and civil unrest menace the mental well-being of millions. Understanding how, in vulnerable people, fear from such frightening events evolves into lifelong anxiety, is critical for healing. A University of New Mexico research team led by Elaine L. Bearer, MD, Ph.D., the Harvey Family...

Long-term use of synthetic corticosteroid drugs increases adrenal gland inflammation
New research by academics at the University of Bristol has found evidence that prolonged treatment of synthetic corticosteroid drugs increases adrenal gland inflammation in response to bacterial infection, an effect that in the long-term can damage adrenal function. Synthetic corticosteroid drugs are widely prescribed to treat many inflammatory and autoimmune diseases but taking a high...

Brain insulin sensitivity determines body weight and fat distribution
by Deutsches Zentrum fuer Diabetesforschung DZD Just where fat is deposited in the body and to what degree a person may benefit from a lifestyle intervention depends, among other things, on how sensitive the brain is to insulin. If the person’s brain responds sensitively to the hormone, a significant amount of weight can be lost,...

Transcranial ultrasound stimulation can modulate hypothalamus: study
by Li Yuan, Chinese Academy of Sciences Transcranial ultrasound stimulation (TUS) is emerging as a non-invasive brain stimulation method that can achieve a highly focused stimulation of deeper brain areas. The hypothalamus is the link between the endocrine and nervous systems. Previous studies showed that ultrasound could induce brain activityand the sensory discrimination ability of...
