Newly discovered subset of brain cells fight inflammation with instructions from the gut

Astrocytes are the most abundant type of cells within the central nervous system (CNS), but they remain poorly characterized. Researchers have long assumed that astrocytes' primary function is to provide nutrients and support ...

Study explores the effects of maternal inflammation on fetal brain development

Past research suggests that infections or inflammation in pregnant women can be linked with the development of neurodevelopmental disorders in their offspring. While this association is well-documented, the molecular and ...

Epilepsy research focused on astrocytes

During epileptic seizures, a large number of nerve cells in the brain fire excessively and in synchrony. This hyperactivity may lead to uncontrolled shaking of the body and involve periods of loss of consciousness. While ...

Fine tuning first-responder immune cells may reduce TBI damage

Immediately after a traumatic brain injury and as long as one year later, there are increased levels of immune cells called ILCs in the brain promoting inflammation, which can worsen brain damage, scientists report.

MRI helps unravel the mysteries of sleep

The state of consciousness changes significantly during stages of deep sleep, just as it does in a coma or under general anesthesia. Scientists have long believed, but couldn't be certain, that brain activity declines during ...

Cases of idiopathic intracranial hypertension on the rise in Wales

(HealthDay)—The incidence and prevalence of idiopathic intracranial hypertension are increasing in Wales, corresponding to increasing body mass index (BMI) in the population, according to a study published online Jan. 20 ...

Neuroscience

Memory fail controlled by dopamine circuit, study finds

In a landmark neurobiology study, scientists from Scripps Research have discovered a memory gating system that employs the neurotransmitter dopamine to direct transient forgetting, a temporary lapse of memory which spontaneously ...
