How to erase a memory—and restore it

Using a flash of light, scientists have inactivated and then reactivated a memory in genetically engineered rats. The study, supported by the National Institutes of Health, is the first cause-and-effect evidence that strengthened ...

Researchers identify the neural circuits that modulate REM sleep

A team of scientists led by Dr. Antoine Adamantidis, a researcher at the Douglas Mental Health University Institute and an assistant professor at McGill University, has released the findings from their latest study, which ...

Critical tool for brain research derived from 'pond scum'

The poster child for basic research might well be a one-celled green algae found in ordinary lakes and ponds. Amazingly, this unassuming creature—called Chlamydomonas—is helping scientists solve one of the most complex ...

'Optogenetics' used to control reward-seeking behavior

Using a combination of genetic engineering and laser technology, researchers at the University of North Carolina at Chapel Hill have manipulated brain wiring responsible for reward-seeking behaviors, such as drug addiction. ...
