New technology allows researchers to precisely, flexibly modulate brain

Credit: Pixabay/CC0 Public Domain Human brain diseases, such as Parkinson’s disease, involve damage in more than one region of the brain, requiring technology that could precisely and flexibly address all affected regions simultaneously. Researchers at Washington University in St. Louis have developed a noninvasive…

Study links balanced neural activity to enhanced cognitive abilities in youth

Study links balanced neural activity to enhanced cognitive abilities in youth

In a world where external and internal stimuli can throw our entire body system off balance, how does our brain prevent itself from becoming overly stimulated? The answer lies in our brain’s ability to maintain the balance of neural excitation (E) and inhibition (I),…

Neural balance in the brain is associated with brain maturity and better cognitive ability

In a world where external and internal stimuli can throw our entire body system off balance, how does our brain prevent itself from becoming overly stimulated? The answer lies in our brain’s ability to maintain the balance of neural excitation (E) and inhibition (I),…

The brain can store nearly 10 times more data than previously thought, study confirms

The brain can store nearly 10 times more data than previously thought, study confirms

The amount of information the brain can store is greater than once thought, new research suggests. The brain may be able to hold nearly 10 times more information than previously thought, a new study confirms. Similar to computers, the brain’s memory storage is measured…

There are plenty of ways to get smarter . You can harness the power of interleaving by learning several things in succession. You can vary the way you study. You can test yourself. Oddly enough, simply getting more sleep can actually make you smarter…

How Brain Waves Influence Your Memory

How Brain Waves Influence Your Memory

Key points Brain waves influence cognitive control and memory formation, informing how the brain manages memory. Working memory stores and manipulates information temporarily for tasks like learning and decision-making. Phase-amplitude coupling neurons synchronize with brain waves, aiding cognitive control and memory retrieval. New findings…

Serotonin Affects Behavior and Motivation

Serotonin Affects Behavior and Motivation

Summary: A new study reveals how activating the brain’s serotonin center affects behavior and motivation in awake mice. Using optogenetics and high-field MRI, researchers found that stimulating serotonin neurons in the dorsal raphe nucleus (DRN) activates the cerebral cortex and basal ganglia, critical areas…

Exercise spurs neuron growth and rewires the brain, helping mice forget traumatic and addictive memories

Researchers from the University of Toronto, Canada, and Kyushu University, Japan, have found that increased neuron formation and the subsequent rewiring of neural circuits in the hippocampus through exercise or genetic manipulation helps mice forget traumatic or drug-associated memories. The findings, reported on May…
