Sex differences found in response to common antidepressant

Women with depression may be much more likely than men to get relief from a commonly used, inexpensive antidepressant drug, a new national study finds. But many members of both sexes may find that it helps ease their depression symptoms.

Brain growth and development in very premature or low-weight infants

Brain development in infants who are born very prematurely is still incomplete. Factors that cause premature birth may have an impact on the development of the premature infant's brain both during pregnancy and later on after birth. A project conducted as part of the Academy of Finland Research Programme on Neuroscience (NEURO) is concerned to study brain growth and development invery premature or low-weight infants.

Diazepam effects nerve cells in the brain reward system

Addictions to medicines and drugs are thought to develop over a relatively long period of time. The process involves both structural and functional changes in brain nerve cells that are still poorly understood.

Discovery of genes that may predispose to anxiety disorders

Finnish scientists have identified genes that may predispose to anxiety disorders. Research conducted under the supervision of Academy Research Fellow Iiris Hovatta have focused on genes that influence human behaviour, and some of the studied genes show a statistical association with specific anxiety disorders. The work is carried out as part of the Academy of Finland Research Programme on Neuroscience (NEURO).

UT Southwestern discovery may lead to new drug-abuse treatments

Increased connections among brain cells caused by excessive drug use may represent the body's defense mechanism to combat addiction and related behaviors, scientists at UT Southwestern Medical Center have found.

New technique offers hope for stroke sufferers

If a stroke patient doesn't get treatment within approximately the first three hours of symptoms, there's not much doctors can do to limit damage to the brain.

Brain study could lead to new understanding of depression

Brain scientists have moved a step closer to understanding why some people may be more prone to depression than others.

New sleep lab to benefit shift-workers

Two specialist laboratories opening night at the University of Sydney will shed light on the impact of sleep and circadian disruption in medical disorders and shift-workers, and the neurobiological mechanisms underlying substance abuse and depression.

New therapeutic approaches to protect neurons from inflammation and toxicity-induced neurodegeneration

New research led by Chu Chen, PhD, Associate Professor of Neuroscience at LSU Health Sciences Center New Orleans, provides evidence that one of the only naturally occurring fatty acids in the brain that has the ability to interact with the receptors originally identified as the targets of THC (the psychoactive component of marijuana) can help to protect brain cells from neurodegenerative diseases like Alzheimer's and Parkinson's.

Alcohol's effects on childbearing onset across reproductive development

Alcohol use during the teen years can not only lead to subsequent alcohol problems, it can also lead to risky sexual behavior and a greater risk of early childbearing. An examination of the relationship between a lifetime history of alcohol dependence (AD) and timing of first childbirth across reproductive development has found that AD in women is associated with delayed reproduction.

One night without sleep increases chemical dopamine in the human brain

Because drugs that increase dopamine, like amphetamines, promote wakefulness, the findings offer a potential mechanism explaining how the brain helps people stay awake despite the urge to sleep. However, the study also shows that the increase in dopamine cannot compensate for the cognitive deficits caused by sleep deprivation.

New discovery may lead to new drugs to regulate sleep

A team of scientists from Oxford University in the UK have discovered the reason why people feel drowsier in dim lighting and more alert in bright white light.

Research shows Indigenous children don't need number words to count

According to a new international study, Indigenous Australian children who speak languages that have few number words are still able to count.

Aboriginal children can count without numbers

Knowing the words for numbers is not necessary to be able to count, according to a new study of aboriginal children by UCL (University College London) and the University of Melbourne.

URMC & NIH partner to expand, accelerate clinical research in neurological diseases

The University of Rochester Medical Center (URMC) and the National Institute of Neurological Disorders and Stroke are hosting a week-long training session designed to create a new generation of researchers with the specialized skills necessary to conduct clinical trials in neurological disorders.

Infant sensitivity to negative emotional expressions develops at around six months

Scientists working in the Academy-funded Research Programme on Neuroscience (NEURO) have discovered important changes in the way that infants react to another person's face at age 5-7 months.

Bristol University receives new funds for research into stress and the brain

Over £500,000 has been awarded to Bristol University academics to fund research into how stress hormones act in the brain.

Research finds a role for the GABA neurotransmitter in maintaining energy balance

Controlling body weight is a complicated process, as any frustrated dieter might attest. But as scientists continue to investigate the brain's intricate neurocircuitry and its role in maintaining energy balance, they are forming a clearer picture of the myriad events that lead to weight gain and weight loss.

COMT gene variation affects fear processing, anxiety

Inborn differences may help explain why trauma gives some people bad memories and others the nightmare of post-traumatic stress. Scientists in Germany and the United States have reported evidence linking genes to anxious behavior. The findings appear in the August issue of Behavioral Neuroscience, published by the American Psychological Association.
