Microglia are the brain's immune cells that clean out debris, such as damaged proteins and old cell parts, to keep the organ ...

A new study in mice suggests that memory problems in Alzheimer’s disease may stem from a breakdown in how the brain replays recent experiences during periods of rest. The research was carried out by s ...

Researchers outline a roadmap for applying transcranial focused ultrasound, a noninvasive technique for stimulating the brain ...

When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like ...

Scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons. These ...

The sound of a fire alarm tells us to get out quickly to not get hurt, while the sight of a gas station sign can signal a chance to refuel. In everyday life, we learn to link cues we sense with what ...

Research shows that delaying important tasks is often driven by how the brain processes stress and threat—not by poor time ...

A Dartmouth study published in Nature Communications reveals that immune cells in the brain use a surprising two-step process ...

The human brain's soft folds and ridges, arising in early development and continuing through the first 18 months of life, are ...

A heart attack activates stress circuits in the brain that evolved for survival but can amplify inflammation, disrupt healing ...

The brain’s hemispheres are specialized for efficiency. Modern neuroscience shows lateralization enhances function without ...

A new study has identified the brain connectivity patterns that lead to cognitive difficulties in patients with schizophrenia, suggesting potential targets for therapeutic intervention in early ...
