DOI: 10.1371/journal.pbio.3002483A neurotransmitter previously thought only to calm neurons may also play a role in waking them up, according to a study published in the journal PLOS Biology, a discovery which challenges the textbook view of how...
by Bob Yirka , Medical Xpress Overview of receptors and pharmacological rs-fMRI data. (A) For each psychoactive drug, its pattern of pharmacologically induced functional reorganization is quantified as the average (across subjects) of the within-subject difference in regional FC weighted degree (sum of each region’s positive connections) between task-free fMRI scans at baseline and under...
by KAIST Functional shift of somatostatin (SST) by factors in the pathogenesis of Alzheimer’s disease. Credit: KAIST With nearly 50 million dementia patients worldwide, Alzheimers’s disease is the most common neurodegenerative disease. Its main symptom is the impairment of general cognitive abilities, including the ability to speak or to remember. The importance of finding a...

CREDIT: LABORATORY OF NEUROPHYSIOLOGY AND BEHAVIOR AT THE ROCKEFELLER UNIVERSITY Among the neurotransmitters in the brain, dopamine has gained an almost mythical status. Decades of research have established its contribution to...

by University of Utah Health Sciences Credit: CC0 Public Domain Massive “plumes” of glutamate, a key neurotransmitter, surging in the brain could help explain the onset of migraine with aura—and potentially a broad swath of neurologic disease, including stroke and traumatic brain injury—according to an international study led by University of Utah Health scientists. The study,...

CREDIT: L.A. CICERO/STANFORD NEWS SERVICE In 2017, Stanford University researchers presented a new device that mimics the brain’s efficient and low-energy neural learning process. It was an artificial version of a synapse – the gap across which neurotransmitters travel to communicate between neurons – made from organic materials. In 2019, the researchers assembled nine of...
by FAPESP Autism has long been associated only with behavioral and environmental factors, but the role of genetics in its development is now increasingly evident. Some 100 genes have been found to play a role in autism spectrum disorder, and another thousand are being studied to the same end. The diagnosis and treatment of the...
