Neuronal circuits for fine motor skills

Writing, driving a screw or throwing darts are only some of the activities that demand a high level of skill. How the brain masters such exquisite movements has now been described. A map of brainstem circuits reveals which neurons control the fine moto…

Identifying strategies to advance research on traumatic brain injury’s effect on women

New work reveals gaps in and opportunities for research to improve understanding of the effects of traumatic brain injury (TBI) in women.

Link between dietary fiber and depression partially explained by gut-brain interactions

Fiber is a commonly recommended part of a healthy diet. That’s because it’s good for your health in so many ways — from weight management to reducing the risk of diabetes, heart disease, and some types of cancer. A new study also finds that it might b…

Patient-reported loss of smell in 86 percent of mild COVID-19 cases, study finds

Repeated ketamine infusions reduce PTSD symptom severity

Repeated intravenous (IV) ketamine infusions significantly reduce symptom severity in individuals with chronic post-traumatic stress disorder (PTSD) and the improvement is rapid and maintained for several weeks afterwards, according to a new study.

Anticoagulants reduce the number of brain metastases in mice

Brain metastases can only develop if cancer cells exit the capillaries and enter into the brain tissue. To facilitate this step, cancer cells influence blood clotting, as scientists have now been able to show in mice. The cancer cells actively promote …

Bedside EEG test can aid prognosis in unresponsive brain injury patients

Assessing the ability of unresponsive patients with severe brain injury to understand what is being said to them could yield important insights into how they might recover, according to new research.

Scientists explore deficits in processing speed in individuals with spinal cord injury

A new study examined the neural mechanisms of higher order cognitive tasks of individuals with SCI.

Brain imaging predicts PTSD after brain injury

Posttraumatic stress disorder (PTSD) is a complex psychiatric disorder brought on by physical and/or psychological trauma. How its symptoms, including anxiety, depression and cognitive disturbances arise remains incompletely understood and unpredictabl…
