by CU Anschutz Medical Campus Credit: Spencer Bowles et al, Neuron (2022). DOI: 10.1016/j.neuron.2022.06.017 Researchers at the University of Colorado Anschutz Medical Campus have shown a direct link between vagus nerve stimulation and its connection to the learning centers of the brain. The discovery may lead to treatments that will improve cognitive retention in both healthy and...

by University of Copenhagen Credit: Unsplash/CC0 Public Domain You wake up. The alarm clock says 02:56. “Oh no, it is not time to wake up yet,” you think, fearing that you will need lots of coffee to stay awake the following day. Most people believe that a good night’s sleep should be uninterrupted. That is why...
by National Institutes of Health Credit: CC0 Public Domain Researchers have found that blocking certain acetylcholine receptors in the lateral habenula (LHb), an area of the brain that balances reward and aversion, made it harder to resist seeking cocaine in a rat model of impulsive behavior. These findings identify a new role for these receptors that...
by Australian Nuclear Science and Technology Organisation (ANSTO) Credit: Pixabay/CC0 Public Domain ANSTO health researchers have contributed to an international study published in Nature Neuroscience that sheds light on the mechanism by which anti-anxiety drugs act on the brain which could lead to cognitive impairment in vulnerable individuals. The research critically depended on a unique laboratory model developed...
by University of Basel Credit: CC0 Public Domain Even before carbohydrates reach the bloodstream, the very sight and smell of a meal trigger the release of insulin. For the first time, researchers from the University of Basel and University Hospital Basel have shown that this insulin release depends on a short-term inflammatory response that takes...
On its surface, the subreddit for irritable bowel syndrome (IBS) is a den of tongue-in-cheek humor; its logo reimagines the classic Reddit alien gripping its gut in discomfort, scatological memes abound, and the most active members sit “on the porcelain throne.” Beyond the joking veneer, however, the online community shares stories of how the disorder has tinged almost every...

UNIVERSITY OF CALIFORNIA – LOS ANGELES HEALTH SCIENCES Our brains rarely record single memories—instead, they store memories into groups so that the recollection of one significant memory triggers the recall of others connected by time. As we age, however, our brains gradually lose this ability to link related memories. Now UCLA researchers have discovered...
by University of Wisconsin-Madison Credit: Unsplash/CC0 Public Domain In the mid-20th century, new evidence showed that the brain could be “plastic,” and that experience could create changes in the brain. Plasticity has been linked to learning new skills, including spatial navigation, aerobic exercise and balance training. Yet it has remained an open question whether mindfulness...
