‘Navigator’ neurons play critical role in sense of smell

Researchers have identified ‘navigator’ neurons that are key to setting up connections in the system responsible for the sense of smell. The new study builds on a breakthrough 2014 report which showed a critical period in olfactory wiring using mice as…

Brainwave activity reveals potential biomarker for autism in children

Autism spectrum disorder (ASD) affects children’s social and intellectual development. Conventional diagnostic methods for ASD rely on behavioral observation. Researchers have now identified a potential quantifiable biomarker for diagnosing ASD. Using …

Sex, drugs and estradiol: Why cannabis affects women differently

Sex differences in cannabis use are beginning to be explained with the aid of brain studies in animals and humans.

How the brain decides what to learn

Neuroscientists know a lot about how our brains learn new things, but not much about how they choose what to focus on while they learn. Now, researchers have traced that ability to an unexpected place.

Hallucinations associated with brain hyperactivity in people with macular degeneration

New research shows for the first time that visual hallucinations in people with macular degeneration are associated with abnormally heightened activity in the visual cortex of the brain. The findings could improve diagnosis of such hallucinations.

Mind’s quality control center found in long-ignored brain area

The cerebellum, once thought to be limited to controlling movement, is involved in every aspect of higher brain function, according to a new study.

Unique patterns of neural communications found in brains of children with autism

A research team studying MRI scans of school-age children’s brains found unique patterns of neural communication involving the amygdala, the area of the brain responsible for processing social information. In children with ASDs, the amygdala connection…

Surprising network activity in the immature brain

One of the outstanding mysteries of the cerebral cortex is how individual neurons develop the proper synaptic connections to form large-scale, distributed networks. Now scientists have gained novel insights from spontaneously generated patterns of acti…

Stress can impair memory, reduce brain size in middle age

Stress may be causing impaired memory and brain shrinkage in middle-age adults, even before symptoms of Alzheimer’s or other dementia begin, according to a new study.
