Important step towards improving diagnosis and treatment of brain metastases

Brain metastases often occur as a result of advanced cancer and, despite medical innovations, are still associated with a poor prognosis. Now, an international expert committee has taken an important step towards improving diagnostics and therapy monit…

Sleep apnea during REM sleep linked to memory-related brain changes

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain’s small blood vessels, according to a new study. The study found the brain …

Discovery of dopamine receptors in a previously overlooked part of the brain sheds light on the complex circuitry for anxiety and depression

Researchers have discovered distinct roles for two dopamine receptors located on nerve cells within the portion of the brain that controls approach vs. avoidance behavior.

A pipette that can activate individual neurons

Researchers have developed a new type of pipette that can deliver ions to individual neurons without affecting the sensitive extracellular milieu. Controlling the concentration of different ions can provide important insights into how individual brain …

Knowing your Alzheimer’s risk may ease anxiety but reduce motivation for healthy habits

Learning about one’s risk for Alzheimer’s disease may not lead to emotional distress, but motivation to maintain healthy lifestyle changes tends to fade over time, even in people at high risk, according to a new study.

Neuroscientists pinpoint where (and how) brain circuits are reshaped as we learn new movements

Brain researchers have identified a bridge between the thalamus and the cortex as the key area that is modified during motor learning functions. They found that such learning does much more than adjust activity levels, it sculpts the circuit’s wiring, …

Study suggests we don’t just hear music, but ‘become it’

Psychologists suggest our brains and bodies don’t just understand music, they physically resonate with it. These discoveries, based on findings in neuroscience, music, and psychology, support Neural Resonance Theory (NRT).

New chronic pain therapy retrains the brain to process emotions

Researchers have created an effective therapy for chronic pain that reduces pain intensity by focusing on emotional regulation.

Neighborhood stress may impact kids’ brains — and increase depression risk

Children who grow up in disadvantaged neighborhoods — areas with higher levels of crime and deprivation, and lower access to community resources — are at risk of developing depression, and new research may help to explain why.

Children as young as five can navigate a ‘tiny town’

Neuroscientists are developing methods to map the brain systems that allow us to recognize and get around our world.
