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…

Upgrading brain storage: Quantifying how much information our synapses can hold

Two neurons, one in full (left, light purple) and one partially out of frame (right, light blue) on top of a background of zeros and ones to symbolize the unit of bits used to quantify information storage in synapses. The neuron on the left…

More Research Links Ultra-Processed Foods to Increased Risk of Cognitive Decline, Stroke

More Research Links Ultra-Processed Foods to Increased Risk of Cognitive Decline, Stroke

New research on the risks associated with consuming ultra-processed foods, shows a correlation rather than causation between the consumption of ultra-processed foods and these health issues. The findings are published in the current issue of the journal Neurology . Ultra-processed foods, which are characterized…

Ultra-Processed Foods an Independent Risk Factor for Poor Brain Health

Ultra-Processed Foods an Independent Risk Factor for Poor Brain Health

0 Consuming highly processed foods may be harmful to the aging brain, independent of other risk factors for adverse neurologic outcomes and adherence to recommended dietary patterns, new research suggests. Observations from a large cohort of adults followed for more than 10 years suggested…

Study shows exercise spurs neuron growth and rewires the brain, helping mice forget traumatic and addictive memories

Study shows exercise spurs neuron growth and rewires the brain, helping mice forget traumatic and addictive memories

Exercise-induced formation of neurons and genetically-inducted neuron growth rewired neural circuits in the hippocampus, helping mice forget traumatic memories and reducing their PTSD-like symptoms.

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…

High BMI Linked to Weak Smell-Eating Circuit in Brain

High BMI Linked to Weak Smell-Eating Circuit in Brain

Summary: A new study reveals a novel brain circuit linking the sense of smell and eating behavior. The weaker the connection between these regions, the higher a person’s Body Mass Index (BMI). This discovery suggests a potential neural mechanism underlying overeating, where disrupted circuits…

Exercise Can Slow Brain Aging Cognitive Decline

Exercise Can Slow Brain Aging Cognitive Decline

Summary: A new study shows that exercise can reverse aging effects in the brain. Researchers found that physical activity alters gene expression in microglia, making them resemble those of younger brains. Exercise also helps reduce harmful T cell presence in the hippocampus, enhancing memory…
