Neuroscientists have artificially increased neuronal activity in part of the brain by briefly shining light on genetically modified neurons. They saw that this manipulation selectively enhanced performance in non-human primates performing a visual atte…

A team has identified a molecular cellular mechanism that is linked to microencephaly, a condition in which a baby’s head is much smaller than expected.

A new study involved high-resolution scans that enabled the researchers to visualize brain connections at submillimeter spatial resolution. Together, these pathways form a ‘default ascending arousal network’ that sustains wakefulness in the resting, co…

During sleep, the brain weakens the new connections between neurons that had been forged while awake — but only during the first half of a night’s sleep, according to a new study.

The team discovered that an essential nutrient called choline is transported into the brain, across the blood-brain barrier, by a protein transporter called FLVCR2. This is discovery will inform future design of drugs for diseases such as Alzheimer’s a…

A simple blood test could allow doctors to determine whether a person may be at higher risk for stroke or cognitive decline during their lifetime, according to a new study.

Researchers have discovered in a preclinical model that cytokines, proteins that control immune response, circulating in maternal blood during pregnancy may mitigate an offspring’s risk for psychiatric conditions. The findings are surprising because ci…

Research shows that a certain kind of visual illusion, neon color spreading, works on mice. The study is also the first to combine the use of two investigative techniques called electrophysiology and optogenetics to study this illusion. Results from ex…

Researchers have developed tiny, flexible devices that can wrap around individual nerve fibers without damaging them. The researchers combined flexible electronics and soft robotics techniques to develop the devices, which could be used for the diagnos…

A brain circuit inhibits food intake during nausea.
