New research shows that blood from older animals can speed up Alzheimer’s-related changes in the brain, while young blood may ...

Synaptic plasticity—the brain's ability to modify the connections between neurons to support learning—is one of the neural ...

Ketamine is a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist that produces rapid antidepressant action in some patients with treatment-resistant depression. However, recent data ...

Increased levels of bioactive lipids produced naturally in the body, which affect excitatory transmission between brain cells, promote mental disorders. However, this mechanism can be rebalanced by ...

Neurons can rapidly rebalance their communication using a structural signal rather than electrical activity, overturning long-held assumptions about how synapses maintain stability.

Parkinson's and Alzheimer's diseases are the two most common neurodegenerative disorders, affecting millions of people worldwide. Published in the Journal of Neuroscience, new research from the ...

Abstract: Neural tissue requires a great metabolic demand despite negligible intrinsic energy stores. As a result, the central nervous system (CNS) depends upon a continuous influx of metabolic ...

Neurons intertwine with small blood vessels in the brain, but how do the two communicate? With elaborate three-dimensional reconstructions of electron microscopy images, scientists led by Jie-Min Jia, ...

The rapid influx of cerebral spinal fluid (CSF) and protein solutes released during cortical spreading depression (CSD) in the brain activates neurons to trigger aural migraine headaches, according to ...

The tongue contains numerous taste buds—tiny sensory organs responsible for detecting taste. Taste buds consist of specialized cells that translate chemical stimuli into neural signals. Among them, ...
