Amygdala stimulates stress responses in adults, say researchers

In contrast to evidence that the amygdala stimulates stress responses in adults, researchers at Yerkes National Primate Research Center, Emory University have found that the amygdala has an inhibitory effect on stress hormones during the early development of nonhuman primates.

Shuganjieyu capsule effectively reverses depressive by increasing neurotrophic factor

Shuganjieyu capsule has been approved for clinical treatment by the State Food and Drug Administration of China since 2008. In the clinic, Shuganjieyu capsule is often used to treat mild to moderate depression.

Higher-fit children have more compact white-matter tracts in the brain than lower-fit peers

A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit. "White matter" describes the bundles of axons that carry nerve signals from one brain region to another. More compact white matter is associated with faster and more efficient nerve activity.

Researchers uncover role of epigenetic changes in Alzheimer's disease

A team led by researchers at the University of Exeter Medical School and King's College London has uncovered some of the strongest evidence yet that epigenetic changes in the brain play a role in Alzheimer's disease.

Study to explain how brain reorganizes itself as children learn math facts

As children learn basic arithmetic, they gradually switch from solving problems by counting on their fingers to pulling facts from memory. The shift comes more easily for some kids than for others, but no one knows why.

Finding may explain why people with schizophrenia have difficulty achieving real-world goals

People with schizophrenia struggle to turn goals into actions because brain structures governing desire and emotion are less active and fail to pass goal-directed messages to cortical regions affecting human decision-making, new research reveals.

NIH-funded study explores how thalamic reticular nucleus influences consciousness

Ever wonder why it's hard to focus after a bad night's sleep? Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions.

Findings may help identify teens who are at risk for dangerous behaviors in the future

According to the CDC, unintentional injuries are the leading cause of death for adolescents. Compared to the two leading causes of death for all Americans, heart disease and cancer, a pattern of questionable decision-making in dire situations comes to light in teen mortality.

Bioengineers create 3D brain-like tissue to study chemical and electrical changes

Bioengineers have created three-dimensional brain-like tissue that functions like and has structural features similar to tissue in the rat brain and that can be kept alive in the lab for more than two months.

Schizophrenia-linked genetic variations and the developing brain: an interview with Prof. Guo-li Ming

How much is currently known about what happens in the developing brain that puts people at risk of schizophrenia?

Study shows noticeable differences in brain function across the day for older adults

Older adults who are tested at their optimal time of day (the morning), not only perform better on demanding cognitive tasks but also activate the same brain networks responsible for paying attention and suppressing distraction as younger adults, according to Canadian researchers.

UCSF researchers identify novel molecular features within the developing human brain

UC San Francisco researchers have identified cells' unique features within the developing human brain, using the latest technologies for analyzing gene activity in individual cells, and have demonstrated that large-scale cell surveys can be done much more efficiently and cheaply than was previously thought possible.

Persons with ASD have trouble in noticing their movement imitated by others

A Japanese research group led by Prof Norihiro Sadato, a professor of the National Institute for Physiological Sciences (NIPS), National Institutes of Natural Sciences (NINS), has found that people with autism spectrum disorders (ASD) have decreased activity in an area in the brain critical for understanding if his/her movement was imitated by others.

Children with fetal alcohol spectrum disorders show weaker brain activation

In the first study of its kind, Prapti Gautam, PhD, and colleagues from The Saban Research Institute of Children's Hospital Los Angeles found that children with fetal alcohol spectrum disorders (FASD) showed weaker brain activation during specific cognitive tasks than their unaffected counterparts.

Acupuncture at Waiguan can activate several brain regions in patients with ischemic stroke

Both acupuncture at Waiguan (SJ5) and sham acupuncture can activate/deactivate several brain regions in patients with ischemic stroke, but there are some difference in Brodmann areas 4, 6, 8, Brodmann areas 7, 39, 40, Brodmann areas 18, 19, 22 and Brodmann areas 13, 24, 32, 28.

Scientists unravel neural circuit that could play important role in autism

The insular cortex is an integral "hub", combining sensory, emotional and cognitive content. Not surprisingly, alterations in insular structure and function have been reported in many psychiatric disorders, such as anxiety disorders, depression, addiction and autism spectrum disorders (ASD).

Prolonged exposure to loud noise alters how the brain processes speech

Prolonged exposure to loud noise alters how the brain processes speech, potentially increasing the difficulty in distinguishing speech sounds, according to neuroscientists at The University of Texas at Dallas.

Alterations to single gene could predict risk of suicide attempt

Johns Hopkins researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that, if confirmed in larger studies, could give doctors a simple blood test to reliably predict a person's risk of attempting suicide.

New electrical pattern in brains predicts how well individual animals fare in stressful situations

Some people can handle stressful situations better than others, and it's not all in their genes: Even identical twins show differences in how they respond.
