Latest Chemical synapse Stories
Scientists say the identification of a specific molecule could be key to understanding the cause of motor neuron disease (MND) and other neurodegenerative disorders.
U.S. scientists say they've found the nervous system uses a specific type of signal to produce stable retinal images despite vigorous head movements.
New research has uncovered a fundamental cellular mechanism that may drive pathological drug-seeking behavior.
UCLA cellular neuroscientists are providing new insights into the mechanisms that underlie long-term memory â€” research with the potential to treat long-term memory disorders.
A protein called Pum regulates the expression of genes that alter synaptic plasticity
Most people know it from experience: After so many hours of being awake, your brain feels unable to absorb any more -- and several hours of sleep will refresh it.
By Anthony J. Brown, MD NEW YORK (Reuters Health) - When someone suffers a stroke, 1.9 million nerve cells in the brain die each minute, and the oxygen-starved brain ages about 3.6 years each hour -- further emphasizing the need for rapid treatment -- researchers say.

The ability of the brain to transmit and process information requires a lifelong commitment to maintaining the integrity of synapses--the special connections that permit the passage of nerve impulses from one nerve cell to another, according to investigators at St. Jude Children's Research Hospital and colleagues in Hokkaido University School of Medicine (Japan). A report on this work appears in the November 15 issue of Nature Neuroscience.
Neurons experience large-scale changes across their dendrites during learning, say neuroscientists at The University of Texas at Austin in a new study that highlights the important role that these cell regions may play in the processes of learning and memory.
