Revolutionary brain stimulation technique shows promise for treating brain disorders
The human brain’s adaptability to internal and external changes, known as neural plasticity, forms the foundation for understanding cognitive functions like memory and learning, as well as various neurological disorders.
Brain receptor patterns separate sensory and cognitive networks, new study finds
Receptor patterns define key organisational principles in the brain, scientists have discovered.
Intoxicated Teenage Rats Wearing “Fitbits” Experience Sleep Disturbance Long After Withdrawing from Alcohol, Underlining Ongoing Struggles for Humans who Drink Heavily in Adolescence
Adolescent rats exposed to alcohol vapor experience persistent sleep disruption after withdrawal, as measured by Fitbit-like tracking devices, a new study has shown. The findings, published in Alcohol: Clinical & Experimental Research, provide insight into the relationship between sleep disturbance and heavy drinking in humans. Although adolescents and young adults may be particularly affected by sleep disturbances associated with drinking, little is known about that connection or its mechanisms. Plausibly, the link between disrupted circadian rhythm and substance use may operate in both directions; for example, irregular sleep cycles, including daytime sleepiness, have been implicated in teen substance use. Daytime sleepiness and disrupted activity in humans can be measured using wearable tracking devices, complementing EEG metrics taken at night. Nevertheless, genetic and lifestyle factors make the relationship between alcohol and sleep problems challenging to study in humans, and ro
FAU, Israel Scientists ‘Team Up’ to Tackle Alzheimer’s-related Mood Disorders
Researchers from Florida Atlantic University, in collaboration with Tel Aviv University, have received a two-year, $379,177 grant from the National Institute on Aging, National Institutes for Health, on a collaborative project to study mood-disorders changes in Alzheimer’s disease.
Scientists find neurochemicals have unexpectedly profound roles in the human brain
Dopamine and serotonin are at work at sub-second speeds to shape how people perceive the world and take action based on their perception. The discovery shows researchers can simultaneously measure the activity of both dopamine and serotonin in disorders ranging from depression to Parkinson’s disease.
Mouse Study Highlights Neurotransmitter Differences When Awake and Under Anesthesia
Article title: Neurotransmitter networks in mouse prefrontal cortex are reconfigured by isoflurane anesthesia Authors: Xiaoying Zhang, Aaron G. Baer, Joshua M. Price, Piet C. Jones, Benjamin J. Garcia, Jonathon Romero, Ashley M. Cliff, Weidong Mi, James B. Brown, Daniel A.…
Exercise Boosts Motor Skill Learning Via Changes in Brain’s Transmitters
Comparing the brains of mice that exercised with those that did not, UC San Diego researchers found that specific neurons switched their chemical signals, called neurotransmitters, following exercise, leading to improved learning for motor-skill acquisition.
