Worms Reveal How Melatonin Works in the Brain to Promote Sleep

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. […]

Extremists struggle with certain kinds of brain processing, research shows

Scientists have found the psychological signature of people who are likely to hold dogmatic or extremist views.  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 […]

Decoded Neurofeedback: Nonconscious Brain Modulation To Remove Fears & Increase Confidence

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 […]

Scientists Solve Long-Standing Brain Mystery by a Whisker

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 Brain Organoids Show How a Single Gene Alteration May Have Separated Modern Humans From Predecessors

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 alters consciousness by breaking down barriers in the brain

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 […]
