Experimental drug and genetic differences indicate how people deal with fear and stress

Researchers at Duke University and the National Institutes of Health have found a way to calm the fears of anxious mice with a drug that alters their brain chemistry. They've also found that human genetic differences related to the same brain chemistry influence how well people cope with fear and stress.

Sleep loss markedly exaggerates emotional reactivity in people with anxiety disorders

New research shows that sleep loss markedly exaggerates the degree to which we anticipate impending emotional events, particularly among highly anxious people, who are especially vulnerable.

Strong link between the amygdala and a baseline level of distrust

Fool me once, shame on you. Fool me twice, shame on my parahippocampal gyrus. Scientists at the Virginia Tech Carilion Research Institute have found that suspicion resides in two distinct regions of the brain: the amygdala, which plays a central role in processing fear and emotional memories, and the parahippocampal gyrus, which is associated with declarative memory and the recognition of scenes.

ACE inhibitors or ARBs could treat and prevent PTSD

Traumatized people who take a class of common blood pressure medications tend to have less severe post-traumatic stress symptoms, researchers have found.

First neurobiological model for third-party punishment

In a paper published online on April 15 by the journal Nature Neuroscience, a pair of neuroscientists from Vanderbilt and Harvard universities has proposed the first neurobiological model for third-party punishment. It outlines a collection of potential cognitive and brain processes that evolutionary pressures could have re-purposed to make this behavior possible.

Systemic inflammation may contribute to depressive symptoms

New research published in the April issue of The Journal of Nuclear Medicine reveals that systemic inflammation causes an increase in depressive symptoms and metabolic changes in the parts of the brain responsible for mood and motivation. With this finding, researchers can begin to test potential treatments for depression for patients that experience symptoms that are related to inflammation in the body or within the brain.

Study shows how brain function differs in children with math anxiety

Scientists at the Stanford University School of Medicine have shown for the first time how brain function differs in people who have math anxiety from those who don't.

Mantra-based meditation shows promise against age-associated cognitive impairment

Researchers at Thomas Jefferson University Hospital determined that mantra-based meditation can have a positive impact on emotional responses to stress, fatigue and anxiety in adults with memory impairment and memory loss.

Causal link between TBI and increased susceptibility to PTSD

Mild traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) are cardinal injuries associated with combat stress, and TBI increases the risk of PTSD development. The reasons for this correlation have been unknown, in part because physical traumas often occur in highly emotional situations.

Traumatic brain injury linked to PTSD: UCLA study

UCLA life scientists and their colleagues have provided the first evidence of a causal link between traumatic brain injury and an increased susceptibility to post-traumatic stress disorder.

Small-group dynamics can alter expression of IQ in some susceptible people

In the classic film "12 Angry Men," Henry Fonda's character sways a jury with his quiet, persistent intelligence. But would he have succeeded if he had allowed himself to fall sway to the social dynamics of that jury? Research led by scientists at the Virginia Tech Carilion Research Institute found that small-group dynamics -- such as jury deliberations, collective bargaining sessions, and cocktail parties -- can alter the expression of IQ in some susceptible people.

Decision-making over 'sacred values' prompts a distinct cognitive process

An Emory University neuro-imaging study shows that personal values that people refuse to disavow, even when offered cash to do so, are processed differently in the brain than those values that are willingly sold.

Brain atrophy is evident in Parkinson's patients with MCI

Atrophy in the hippocampus, the region of the brain known for memory formation and storage, is evident in Parkinson's disease (PD) patients with cognitive impairment, including early decline known as mild cognitive impairment (MCI), according to a study by researchers in the Perelman School of Medicine at the University of Pennsylvania.

Cortex plays a key role in fear learning

The study, initiated by the Swiss researchers and published in Nature, constitutes ground-breaking work in exploring emotions in the brain.

Exposure to family violence may increase brain activity in children

Children exposed to family violence show the same pattern of activity in their brains as soldiers exposed to combat, new research has shown.

Child abuse can affect brain functions later life: Study

According to a new research from Yale University, teenagers who were abused as young children show changes in their brains that put them at risk for behavioral problems in adulthood.

Stress chemicals shut down and brain processes emotional experiences during REM sleep

They say time heals all wounds, and new research from the University of California, Berkeley, indicates that time spent in dream sleep can help. UC Berkeley researchers have found that during the dream phase of sleep, also known as REM sleep, our stress chemistry shuts down and the brain processes emotional experiences and takes the painful edge off difficult memories.

Scientists show that the sense of smell can be improved

In a new study scientists at NYU Langone Medical Center have shown that the sense of smell can be improved. The new findings, published online November 20, 2011, in Nature Neuroscience, suggest possible ways to reverse the loss of smell due to aging or disease.

Sex during adolescence can have negative effects on body and mood well into adulthood

A new study suggests that sex during adolescence can have lasting negative effects on the body and mood well into adulthood, most likely because the activity occurs when the nervous system is still developing.

New research identifies brain chemicals and circuits involved in mental illnesses

New research identifies the brain chemicals and circuits involved in mental illnesses like schizophrenia, depression, and anxiety, giving potential new directions to their treatment.
