Schizophrenia can be caused by structural abnormality in adolescent brain associated with genetic risk

Schizophrenia could be caused by a genetic mutation that causes a structural abnormality in the brain during adolescence. Therefore testing for the gene SLC39A8, and brain scans for schizophrenia could predict whether or not someone will develop it, re…

Alterations in hippocampal structural connections differentiate between responders of ECT

A new study in people with major depression reports that electroconvulsive therapy (ECT) induces changes in the fibers connecting the hippocampus to brain regions involved in mood and emotion.

Born to run: Just not on cocaine

A study finds a surprising response to cocaine in a novel strain of mutant mice — they failed to show hyperactivity seen in normal mice when given cocaine and didn’t run around. In other tests, they still found cocaine appealing, but displayed an inab…

Differences among brain neurons that coincide with psychiatric conditions

Scientists have found about 13,000 regions of epigenetic differences between neurons in different brain regions that vary by at least 10 percent. The location of those epigenetic changes — covering about 12 million bases in the genome — co-locate wit…

A new way by which the human brain marks time

With a little help from HBO’s ‘Curb Your Enthusiasm,’ neurobiologists have uncovered a key component of how the human brain marks time.

Helping anxious students excel on science exams

A new study released today reveals that helping lower-income high school freshman to regulate their test-taking anxiety can cut their biology course failure rates in half. The study, published in Proceedings of the National Academy of Sciences and cond…

Early child deprivation and neglect impair memory and executive functioning at age 16

Young children experiencing deprivation and neglect in institutional settings have impaired memory and executive functioning at ages 8 and 16 compared with peers placed early in quality foster homes, report investigators.

The 17 different ways your face conveys happiness

Human beings can configure their faces in thousands and thousands of ways to convey emotion, but only 35 expressions actually get the job done across cultures, a new study has found.

Stroke drug may also prevent Alzheimer’s disease

Researchers have discovered that a drug currently being developed to treat stroke patients could also prevent Alzheimer’s disease. The study shows that the genetically engineered protein 3K3A-APC protects the brains of mice with Alzheimer’s-like sympto…

Teen brain volume changes with small amount of cannabis use, study finds

At a time when several states are moving to legalize recreational use of marijuana, new research shows that concerns about the drug’s impact on teens may be warranted. The study shows that even a small amount of cannabis use by teenagers is linked to d…
