Increased levels of dopamine play an important role in transition to REM sleep, mice study suggests

What triggers the mammalian sleep cycle's shift between non-rapid eye movement (NREM) and rapid eye movement (REM) sleep? A new study in mice suggests increased levels of dopamine in a key region of the brain during NREM sleep play an important role in this transition.

Individuals with alcohol problems may have lower functional connectivity in brain regions that process emotions

People predisposed to heavy drinking and alcohol problems may have lower functional connectivity -; the patterns of signaling between brain areas -; in regions that process emotions and social situations.

Toxic goiter affects the brain more than previously thought

Toxic goiter affects the brain more than was previously known, a University of Gothenburg study shows, and involves volume changes occurring in central parts of the brain.

Efficacy of MVA-CoV2-S vaccination to prevent SARS-CoV-2 cerebral infection and associated damage

Researchers demonstrated that an MVA vector expressing the SARS-CoV-2 spike protein was 100% effective in preventing neuroinvasion and brain damage by SARS-CoV-2 in transgenic mice.

TTUHSC project awarded new NIH grant to advance research on amygdala pain mechanisms

It is estimated that more than 100 million U.S. adults are affected by chronic pain, a condition that annually costs the country an estimated $560-635 billion in health care costs, disability and lost productivity.

Research provides new insights on memory loss in Alzheimer's disease

Members of the "Synaptic Dysfunction and Disease" group at the Institute of Biomedicine of Seville, led by researchers Francisco Gómez Scholl and Amalia Martínez Mir, recently published the results of their research into Alzheimer's disease.

New study links anxiety and PTSD to increased myelin in brain's gray matter

A recent study links anxiety behavior in rats, as well as post traumatic stress disorder (PTSD) in military veterans, to increased myelin - a substance that expedites communication between neurons - in areas of the brain associated with emotions and memory.

Potential link between SARS-CoV-2 infection and secondary occurrence of anti-NMDAR encephalitis

Scientists explore the link between SARS-CoV-2 infection and anti-NMDAR encephalitis.

Repeated dopamine release in the brain plays a key role in infant social development

Changing levels of the chemical dopamine, a chemical most associated with motivation, may help explain why stressful experiences during infancy can lead to lasting behavioral issues, a new study in rodents shows.

People's eyes widen in response to interest and engagement, finds study

As busy people, we juggle many tasks, keep many balls in the air, and try to avoid letting anything drop. In class, instructors toss out ideas; sometimes they go over our heads, but other times we grasp them quickly.

Prenatal maternal distress during COVID linked to alterations in infant brain development

A new study discusses the effects of stress during pregnancy in the pandemic on the developing brain of the infant.

Study confirms how profoundly the brain is affected by major depression

Scientists have found that the more severely patients have been hit by depression across their lifespan, the less they react emotionally to negative faces during current depression.

Research finds increases in 'pandemic brain' after COVID-19 lockdowns

Chances are, the COVID-19 pandemic has affected your health — even if you have never been infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). According to new research from Harvard Medical School, the stress of isolation from lockdown and stay-at-home measures is making people sick.

Withdrawal from psychostimulants alters functional architecture and patterns in the brain

Addictive psychostimulants, from nicotine in cigarettes to illicit drugs like methamphetamine and cocaine, affect different regions of the brain. The same is believed true during withdrawal; finding a common brain pathway has proved elusive.

Study reinforces that dementia with Lewy bodies can be classified into two different disease types

Results obtained in a study recently completed at the University of Helsinki and Helsinki University Hospital reinforce the notion that dementia with Lewy bodies can be pathologically classified into two different disease types.

Research uses rodent models to connect the influence of feronomic signals on memory

The work, published recently in Nature Communications, used a model of rodents and managed to connect for the first time the influence of feronomic signals on memory. This will make it possible to explore the deficits of integration of spatial memories and social studies in transgenic models of Alzheimer's disease in the future.
