Brain stimulation could improve memory while you sleep

Using a noninvasive brain stimulation technique, researchers demonstrated that nocturnal stimulation could enhance memory consolidation during sleep.

Widespread connections among neurons help the brain distinguish smells

Organization — or lack of it — in brain’s piriform cortex allows us to differentiate one smell from another.

Omega-3s help keep kids out of trouble

Something as simple as a dietary supplement could reduce disruptive, even abusive behavior, according to newly released research.

Link found between resilience to dyslexia and gray matter in the frontal brain

A new joint study identifies the brain mechanism that accounts for the discrepancy between low decoding skills and high reading comprehension in some children with dyslexia.

Scientists uncover new connection between smell and memory

Neurobiologists have identified a mechanism that allows the brain to recreate vivid sensory experiences from memory, shedding light on how sensory-rich memories are created and stored in our brains. Using smell as a model, the findings offer a novel pe…

Giant neurons in the brain may play similarly giant role in awareness and cognition

Scientists find that certain neurons release nitric oxide onto nearby blood vessels, and potentially use this mechanism to control awareness in the brain.

Cognitive consequences of age-related increase in brain activity

Increased frontal brain activity in healthy older adults reflects reduced efficiency rather than a way to maintain cognitive function, finds a study of two human samples. The findings contradict a leading theory in the neuroscience of aging.

Mother’s touch supports pup’s brain development

A mother’s presence may have immediate and long-term effects on her child’s developing brain by modulating the serotonin system, suggests a study of rat moms and their pups. The research provides a potential mechanism by which separating a child from h…

Overnight brain stimulation improves memory

New research in humans demonstrates the potential to improve memory with a non-invasive brain stimulation technique delivered during sleep. The results come from a project that aims to better understand the process of memory consolidation, which could …

How dying neurons control eating behaviors of the brain microglia

A new study provides important insight into how microglia, cells that form a branch of the immune system inside the brain, go about their job of clearing out dying and non-functional neurons — and how they sometimes mistakenly attack healthy neurons, …
