The Caennorhabditis elegans worm’s neurons expressing the receptor for melatonin glow green. Credit: Bojun Chen/UConn Health Research in C. elegans shows how melatonin activates the BK channel in the brain. Melatonin is used as a dietary supplement to promote sleep and get over jet lag, but nobody really understands how it works in the brain. […]

It makes sense, the researchers said, as people who are dogmatic tend to be impulsive but also slow to process perceptual information. Extremists — regardless of whether they are right-wing or left-wing — also tend to struggle with […]

Researchers release large dataset on machine learning-based brain training. In recent years, researchers have discovered ways to remove specific fears from the brain, increase one’s own confidence, or even change people’s preferences, by using a combination of artificial intelligence and brain scanning technology. Their technique could lead to new treatments for patients with conditions such […]

UC Riverside mouse study shows where in the brain sensory input is transformed to movement. When we step on the car brake upon seeing a red traffic light ahead, a sequence of events unfolds in the brain at lightning speed. The image of the traffic light is transferred from our eyes to the visual cortex, […]

Neanderthal-ized brain organoids (left) look very different than modern human brain organoids (right) — they have a distinctly different shape, and differ in the way their cells proliferate and how their synapses form. Credit: UC San Diego Health Sciences Novel study used brain organoids genetically modified to mimic now-extinct Neanderthals. As a professor of pediatrics […]

LSD may alter consciousness by freeing the brain from its natural barriers, allowing neurons that wouldn’t normally interact, to have unusual conversations, brain scans show. Investigating how “mind-altering” substances such as LSD can change the brain can be a “powerful method for interrogating and understanding” how the mind meets the brain, the authors wrote in […]
