Cell in zebrafish critical to brain assembly, function

New research documents the presence of astrocytes in zebrafish, a milestone that will open new avenues of research into a star-shaped type of glial cell in the brain that is critical for nearly every aspect of brain assembly and function.

Brain stimulation reduces dyslexia deficits

Restoring normal patterns of rhythmic neural activity through non-invasive electrical stimulation of the brain alleviates sound-processing deficits and improves reading accuracy in adults with dyslexia, according to a new study.

Research unravels what makes memories so detailed and enduring

Researchers report a breakthrough in understanding how memories can be so distinct and long-lasting without getting muddled up.

Older women with type 2 diabetes have different patterns of blood use in their brains

A researcher is reporting that the brains of older women with Type 2 diabetes do not use as much oxygenated blood as those who don’t have the disease. The research is the first to point to changes in blood use in the brain as the primary reason for dia…

Star-cells ‘shine’ to make sense of touch

A research group reports a rather surprise finding as to how GABA works to control the tactile sense. GABA, known for its inhibitory function, actually enhances the sensory input processing by accelerating the signal processing and sharpening the sensi…

As information flows through brain’s heirarchy, higher regions use higher frequency waves

To produce your thoughts and actions, your brain processes information in a hierarchy of regions along its surface, or cortex, ranging from “lower” areas that do basic parsing of incoming sensations to “higher” executive regions that formulate your pla…

Brain’s immune cells promising cellular target for therapeutics

Inspired by the need for new and better therapies for neurodegenerative diseases, researchers are exploring the link between uncontrolled inflammation within the brain and the brain’s immune cells, known as microglia, which are emerging as a promising …

Children use both brain hemispheres to understand language, unlike adults

Infants and young children have brains with a superpower, of sorts, say neuroscientists. Whereas adults process most discrete neural tasks in specific areas in one or the other of their brain’s two hemispheres, youngsters use both the right and left he…

Offspring of mice fed imbalanced diets shown to be neurologically ‘programmed’ for obesity

Pregnant mice fed diets high in omega-6 fats and low in omega-3 fats are shown in a new study to produce offspring whose brains had a higher level of dopamine-producing neurons — the neurological reward system. These mice went on to chase hyper-calori…

Anxiety and depression are associated with medical care avoidance during the pandemic

New research shows U.S. adults who experience common symptoms of anxiety and depression are at greater risk of delaying medical care and not receiving non-COVID-19 medical care amidst the pandemic.
