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

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

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 ...

Scientists show that specifying the timing pattern of neurostimulation -- impulses used to activate the brain's own electrical signaling mechanisms -- can rebalance the strength of synaptic ...

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 ...

A high-speed “zap-and-freeze” method is giving scientists their clearest view yet of how brain cells send messages. By freezing tissue at the instant a signal fires, researchers revealed how synaptic ...

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, ...

A biochemical analysis of brains of deceased individuals with Alzheimer’s disease found markers of impaired insulin signaling ...
