Virginia Tech scientists advance understanding of blood-brain barrier health

in a study with potential impacts on a variety of neurological diseases, Virginia Tech researchers have provided the first experimental evidence from a living organism to show that an abundant, star-shaped brain cell known as an astrocyte is essential for blood-brain barrier health.

Concussion discovery reveals dire, unknown effects of even mild brain injury

Even mild concussions cause severe and long-lasting impairments in the brain’s ability to clean itself, and this may seed it for Alzheimer’s, dementia and other neurodegenerative problems.

‘Brain Surfing’: Ultrasound waves focused on prefrontal cortex elevate mood and change brain connectivity in human volunteers

A team of researchers at the University of Arizona has found that low-intensity ultrasound waves directed at a particular region of the brain’s prefrontal cortex in healthy subjects can elevate mood, and decrease connectivity in a brain network that has been shown to be hyperactive in psychiatric disorders. The method uses transcranial focused ultrasound (‘tFUS’), a painless, non-invasive technique to modulate brain function comparable to transcranial magnetic stimulation (‘TMS’), and transcranial direct current stimulation (‘tDCS’). This study shows, for the first time, a correlation between tFUS-induced mood enhancement, and reorganization of brain circuits.

Study Reveals New Way to Treat Stroke Using an Already FDA-Approved Drug

Granulocyte colony-stimulating factor (GCSF) is currently used to treat neutropenia due to chemotherapy and has been successfully used for patients who require bone marrow transplants. The study is the first to report on the neuroprotective effect of GCSF in vivo and showed that it improved neurological deficits that occur in the first few days following cerebral ischemia. GCSF improved long-term behavioral outcomes while also stimulating a neural progenitor recovery response in a mouse model.

Researchers develop cell therapy to improve memory and stop seizures in mice following traumatic brain injury

Researchers from the University of California, Irvine developed a breakthrough cell therapy to improve memory and prevent seizures in mice following traumatic brain injury. The study, titled “Transplanted interneurons improve memory precision after traumatic brain injury,” was published today in Nature Communications.
