Drug eases recovery for those with severe alcohol withdrawal

Scientists say a drug originally developed to treat high blood pressure can reduce severe withdrawal symptoms for patients diagnosed with alcohol use disorder.

Taking out the trash is essential for brain health

Researchers have identified a protein called Wipi3 that is essential for cellular waste disposal via the alternative autophagy system. Deletion of Wipi3 in the brains of mice causes growth and motor defects attributed to neuronal accumulation of iron, …

Does air pollution increase women’s risk of dementia?

Older women who live in locations with higher levels of air pollution may have more brain shrinkage, the kind seen in Alzheimer’s disease, than women who live in locations with lower levels, according to a new study.

For neural research, wireless chip shines light on the brain

Researchers have developed a chip that is powered wirelessly and can be surgically implanted to read neural signals and stimulate the brain with both light and electrical current. The technology has been demonstrated successfully in rats and is designe…

Early details of brain damage in COVID-19 patients

Looking at six patients using a specialized magnetic resonance technique, researchers found that COVID-19 patients with neurological symptoms show some of the same metabolic disturbances in the brain as other patients who have suffered oxygen deprivati…

Technology lets clinicians objectively detect tinnitus for first time

A technology called functional near-infrared spectroscopy (fNIRS) can be used to objectively measure tinnitus, or ringing in the ears, according to a new study.

A regular dose of nature may improve mental health during the COVID-19 pandemic

A new study suggests that nature around one’s home may help mitigate some of the negative mental health effects of the COVID-19 pandemic.

Learning a new language changes the brain’s division of labor

Learning a language later in life changes how the two halves of the brain contribute. As skills improve, language comprehension changes hemisphere specialization, but production does not, according to new research.

Motor neural population activity patterns are different for reach and grasp behaviors

A new study has found that neuronal population dynamics in the motor cortex are very different during reaching and grasping behavior, challenging a popular theory that indicated intrinsic, dynamic patterns control motor behaviors.

Changes to the brain’s reward system may drive overeating in mice

A combination of innate differences and diet-induced changes to the reward system may predispose some mice to overeat, according to research recently published in JNeurosci.
