Variant of the dopamine receptor gene may be associated with ADHD

A variant of the dopamine receptor gene may be associated with attention-deficit/hyperactivity disorder (ADHD) and with thinner tissue in areas of the brain that handle attention, but also appears associated with better clinical outcomes among individuals with the disorder, according to a report in the August issue of Archives of General Psychiatry , one of the JAMA/Archives journals.

Scientists make female mice act blokey!

By short-circuiting the sensory organ that detects the chemical cues mice use to attract mates, a team of Howard Hughes Medical Institute (HHMI) researchers has prompted female mice to behave like male mice in the throes of courtship.

Study links brain anatomy to the ability to learn a second language in adulthood

Think you haven't got the aptitude to learn a foreign language, New research led by Northwestern University neuroscientists suggests that the problem, quite literally, could be in your head.

Why and when we started walking on two legs

Studying chimpanzees trained to use treadmills, a team of anthropologists has gathered new evidence suggesting our earliest apelike ancestors started walking on two legs because it required less energy than getting around on all fours.

Discovery of new brain mechanism involved with waking up

How do we wake up? How do we shift from restful sleep to dreaming? Researchers at the University of Arkansas for Medical Sciences (UAMS) have discovered a new brain mechanism that just might explain how we do that.

Cicardian system suffers and protects from prenatal cocaine exposure

Researchers from Boston University School of Medicine (BUSM) have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission.
