How does being bilingual affect your brain? It depends on how you use language

Depending on what you read, speaking more than one language may or may not make you smarter. These mixed messages are understandably confusing, and they’re due to the fact that nothing is quite as simple as it’s typically portrayed when it comes to neuroscience. We can’t give a simple “yes” or “no” to the question of whether being bilingual benefits […]

The Brain Disorder in the New Netflix Show 'Away' Really Can Cause Stroke-Like Symptoms—Here's What Doctors Say About It

The new TV series, Away, dropped on Netflix earlier this month, and at the heart of this space drama is a little-known brain condition called cerebral cavernous malformation (CCM). Hilary Swank stars as NASA astronaut Emma Green, and Josh Charles takes the role of her on-screen astronaut husband, Matt Logan. While Swank's character embarks on a mission to Mars, her […]

Point-of-care biomarker assay for traumatic brain injury

Intracranial abnormalities on CT scan in patients with traumatic brain injury (TBI) can be predicted by glial fibrillary acidic protein (GFAP) levels in the blood. These interim findings from the TRACK-TBI study are published in the peer-reviewed Journal of Neurotrauma. GFAP’s diagnostic performance was significantly better than that of the S100B biomarker, to which it was compared. S100B is approved […]

Research team pinpoints brain circuitry underlying dissociative experiences

It’s neither uncommon nor especially worrisome for people to lose themselves in a great book or a daydream. But it’s disconcerting when feeling transported becomes so intense as to seem that one is literally separated from one’s own mind or body. Between 2% and 10% of the population will experience the mysterious phenomenon known as dissociation during their lifetimes, said […]

Stress overload and pain common among patients with traumatic brain injury

Traumatic brain injury (TBI) is a leading cause of death and disability. Post-injury distress is common, with many individuals experiencing chronic anxiety and depressive symptoms as well as chronic pain. In this collection of articles in the journal NeuroRehabilitation, experts report on findings that shed light on the relationship between stress and pain following a TBI and implications for rehabilitation. […]

How to map brain connections using DNA barcodes

A new method developed at Cold Spring Harbor Laboratory (CSHL) uses DNA sequencing to efficiently map long-range connections between different regions of the brain. The approach dramatically reduces the cost of mapping brain-wide connections compared to traditional microscopy-based methods. Neuroscientists need anatomical maps to understand how information flows from one region of the brain to another. “Charting the cellular connections […]

How coronavirus affects the brain

Six months into the COVID-19 pandemic, we’re still learning what the disease can do. There are now detailed reports of brain illness emerging in people with relatively mild lung illness, in those who are critically ill and also in those in recovery. One key thing we’re seeing is that severity of lung illness doesn’t always correlate with severity of neurological […]
