Motherhood may cause brain to grow

Motherhood may actually cause the brain to grow, not turn it into mush, as some have claimed. Exploratory research published by the American Psychological Association found that the brains of new mothers bulked up in areas linked to motivation and behavior, and that mothers who gushed the most about their babies showed the greatest growth in key parts of the mid-brain.

Many antisocial boys may have malfunctioning brains

Antisocial boys who abuse drugs, break laws, and act recklessly are not just "bad" kids. Many of these boys may have malfunctioning brains, according to a new study by researchers at the University of Colorado School of Medicine.

Researchers find heightened activation of limbic circuitry in borderline personality disorder patients

The notion that cutting or burning oneself could provide relief from emotional distress is difficult to understand for most people, but it is an experience reported commonly among people who compulsively hurt themselves.

Specific type of neurons determine frightening stimulus reaction: Research

Fear can make you run, it can make you fight, and it can glue you to the spot. Scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy and GlaxoSmithKline in Verona, Italy, have identified not only the part of the brain but the specific type of neurons that determine how mice react to a frightening stimulus.

New research with agitated monkeys may help predict childhood anxiety & depression

According to the latest discovery from the University of Wisconsin-Madison School of Medicine and Public Health, there may be a possible link between brain activity and childhood anxiety.

Increased brain activity predicts anxious temperament in young primates

A new study focused on anxiety and brain activity pinpoints the brain regions that are relevant to developing childhood anxiety. The findings, published in the Aug. 12 edition of the journal Nature, may lead to new strategies for early detection and treatment of at-risk children.

Scientists identify chemical system effective in cocaine-addiction cure

UT Southwestern Medical Center researchers have identified a chemical system in the brain that reacts differently in cocaine addicts, findings that could result in new treatment options for individuals addicted to the drug."We found that the amount of blood flow in areas of the brain known to be involved in the rewarding effects of cocaine and craving was different in cocaine addicts, compared with healthy subjects," said Dr. Bryon Adinoff, professor of psychiatry at UT Southwestern and lead author of a study that appeared in Neuropsychopharmacology. "Now we have a new target for pharmacologic intervention."

University of Pennsylvania announces recipients of 2010 Templeton Positive Neuroscience Awards

The Positive Psychology Center of the University of Pennsylvania and the John Templeton Foundation have announced the recipients of the 2010 Templeton Positive Neuroscience Awards, $2.9 million given to 15 new research projects at the intersection of neuroscience and positive psychology.

Other brain regions compensates loss of amygdale: Research

Many neuroscientists believe the loss of the brain region known as the amygdala would result in the brain's inability to form new memories with emotional content. New UCLA research indicates this is not so and suggests that when one brain region is damaged, other regions can compensate.

Plea for Federal legislation to ban mercury in vaccines, prevent autism

Two papers in this week's neuroscience journal Acta Neurobiologiae Experimentalis point to vaccines and heavy metals including mercury as causes of the alarming rise in autism. The Centers for Disease Control now estimate autism to affect one in 110 children, up 40% from just a few years ago.

Brains of overweight people are less sensitive to feelings of hunger, finds new research

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior, the foremost society for research into all aspects of eating and drinking behavior, finds that that feelings of hunger have less influence on how the brain responds to the smell and taste of food in overweight than healthy weight individuals.

Brain scanning study has implications for advertising and public health campaigns

In a study with implications for the advertising industry and public health organizations, UCLA neuroscientists have shown they can use brain scanning to predict whether people will use sunscreen during a one-week period even better than the people themselves can.

Abusive attachments during infancy have negative consequences in social behavior development

In a new Biological Psychiatry article, Dr. Regina Sullivan and colleagues have dissected the behavior of mother rats and their infant pups, modeling nurturing by stroking and abuse with electric shock. In this animal model of infant abuse, they took into consideration the unique infant neurobehavioral learning attachment system that ensures infant rats' attachment to their caregiver regardless of the quality of care received.

Serotonin transporter gene appears to increase one's risk for depression, PTSD: Study

There is a great deal of interest in factors that contribute to the vulnerability to developing post-traumatic stress disorder, or PTSD. One factor that appears to contribute to the heritable vulnerability to PTSD is a variation in the gene that codes for the serotonin transporter, also known as the serotonin uptake site. Having a shorter version of the serotonin transporter gene appears to increase one's risk for depression and PTSD after exposure to extremely stressful situations.

Research findings hold promise for debilitating emotional symptoms of FXS

The study, which appears in the journal the Proceedings of the National Academy of Sciences, is also of potential therapeutic significance-it showed that a brief pharmacological treatment is capable of correcting some of these synaptic deficits in mice genetically engineered to model FXS.

Research finding suggests possibilities for future treatment of anxiety disorders

Researchers at the University of Puerto Rico, School of Medicine have found a way to pharmacologically induce a memory of safety in the brain of rats. As reported in the June, 4 2010 issue of Science, administering brain-derived neurotrophic factor into the prefrontal cortex prevented rats from expressing fear to a tone that had been previously paired with a shock.

Study shows direct cellular interaction between endocannabinoids and alcohol in the brain

In findings that should finally put to rest a decade of controversy in the field of neurobiology, a team at The Scripps Research Institute has found decisive evidence that a specific neurotransmitter system-the endocannabinoid system-is active in a brain region known to play a key role in the processing of memory, emotional reactions, and addiction formation. The new study also shows that this system can dampen the effects of alcohol, suggesting an avenue for the development of drugs to combat alcohol addiction.
