Neuroscientists identify brain circuit that integrates head motion with visual signals

Neuroscientists have identified a circuit in the primary visual cortex (V1) of the brain that integrates head- and visual-motion signals. The study elucidates the mechanisms by which visual and vestibular inputs to the brain sum together to enable appr…

Brain mechanism involved in language learning

Psychologists found that when we learn the names of unfamiliar objects, brain regions involved in learning actively predict the objects the names correspond to.

The brain puts the memories warehouse in order while we sleep

During the hours of sleep the memory performs a cleaning shift. A study reveals that when we sleep, the neural connections that collect important information are strengthened and those created from irrelevant data are weakened until they get lost.

How to deal with bad news

Whether you’ve lost your job or just found out that a loved one has passed away, bad news of any kind can cause distress. Here are some ways to cope.

Underlying cause of brain injury in stroke

New research shows how the drug QNZ-46 can help to lessen the effects of excess release of glutamate in the brain — the main cause of brain injury in stroke. As stroke is the second leading cause of disability and early death in the UK, this study cou…

Scientists illuminate mechanism at play in learning

The process we call learning is in fact a well-orchestrated symphony of thousands of molecular reactions, but the exact interplay between these reactions remains largely unknown. Now, researchers have modeled the molecular basis of learning in the cere…

Nightmares are common but underreported in US military personnel

A new study shows that a high percentage of military personnel with sleep disturbances met criteria for nightmare disorder, but few of them reported nightmares as a reason for sleep evaluation. Those with nightmare disorder had an increased risk of oth…

Researchers link defects in a nuclear receptor in the brain to autism spectrum disorders

Scientists are reporting that defects in a portion of the brain’s hippocampus, called the dentate gyrus, is regulated by the nuclear receptor LXR? (Liver X receptor Beta). The dentate gyrus, or DG, is responsible for emotion and memory and is known to …

Making new memories is a balancing act

Salk scientists discover that brain storage capacity is dynamic and varies by region.

Could mindfulness prevent major depression?

A weekly session of mindfulness meditation may help to prevent the development of major depression in those with subclinical depression, a new study finds.
