New research detects brain cell that improves learning

The workings of memory and learning have yet to be clarified, especially at the neural circuitry level. But researchers have now discovered a specific brain neuron with a central role in learning. The study may have a bearing on the potential for count…

New brain pathway for escaping predators found

New research reveals how the zebrafish brain perceives and reacts to predators.

Neuronal ‘barcodes’ shape complex networks in the brain

Understanding how billions of brain cells succeed in making precise connections is a major challenge for neuroscientists. Researchers have unraveled a molecular code that determines the shape, location and function of connections between individual neu…

Pathway of Alzheimer’s degeneration discovered

Scientists have used a unique approach to track brain degeneration in Alzheimer’s disease, uncovering a pathway through which degeneration spreads from one region to another.

How do your conversations affect your well-being?

Does small talk make you unhappy? And, conversely, do meaningful conversations boost your well-being? A new study strives to answer these questions.

Shining new light on the pineal gland

Biologists have identified a gene controlling left-right asymmetry in the brain and sleep-wake cycles.

How to safely stop antidepressants

People may wish to stop taking antidepressants for several reasons, but stopping suddenly can cause withdrawal symptoms or relapse. Here, we look at why stopping antidepressants can be hard and how to relieve withdrawal symptoms. We discuss which antid…

Sleep disorder linked with changes to brain structure typical of dementia

Obstructive sleep apnea is associated with changes to the structure of the brain that are also seen in the early stages of dementia, according to a new study.

Brain study paves way for therapy for common cause of dementia

Scientists have uncovered a potential approach to treat one of the commonest causes of dementia and stroke in older people. Studies with rats found the treatment can reverse changes in blood vessels in the brain associated with the condition, called ce…

Why males are more at risk than females for neurodevelopmental disorders

Researchers have recently begun to realize that biological sex plays a key role in disease risk. Sex plays a role in hypertension, diabetes, arthritis — and in many neurological and psychiatric disorders. Depression and anxiety affect females more, wh…
