In a first, human study shows how dopamine teaches our brain new tricks

More than just the ‘rewards’ chemical, dopamine helps our brains avoid negative experiences based on previous ‘punishment’ For the first time, dopamine regulation has been mapped in real time, deep inside the brains of three humans, revealing how the brain neurotransmitter plays an essential…

Exercise Boosts Brain Power—Neuroscientists Don’t Know How

Exercise Boosts Brain Power—Neuroscientists Don't Know How

Key points Moderate-intensity aerobic exercise (cardio) increases prefrontal cortex oxygenation and boosts brain power. Even with an insufficient oxygen supply or acute hypoxia, doing cardio can improve cognitive performance. Increased cerebral blood flow alone may not explain why aerobic exercise improves executive function. Vitalii…

Probe Into Brain’s Memory Center Could Solve Mystery of Alzheimer’s Cause

Probe Into Brain's Memory Center Could Solve Mystery of Alzheimer's Cause

U.S. researchers are developing a new tool—a multipurpose fiber that will provide a window into the deep brain—with the goal of learning how to slow down or even reverse memory loss in Alzheimer’s disease. Barely thicker than a strand of human hair, the tiny…

Hunger Games: How Gut Hormones Hijack the Brain’s Decision Desk

Hunger Games: How Gut Hormones Hijack the Brain’s Decision Desk

Scientists have discovered that a hunger hormone in the gut directly influences the brain’s hippocampus, affecting decision-making related to food. The study, conducted on mice, showed that hunger hormones modify brain activity to either inhibit or permit eating based on the animal’s hunger level….

Heartbeats and brain activity: Study provides insight into optimal windows for action and perception

(Photo credit: OpenAI’s DALL·E) A new study published in PLOS Biology suggests that our heartbeat plays a crucial role in determining our brain’s ability to perceive and react to the world around us. Researchers have discovered that during the 0.8 seconds of a heartbeat,…
