Latest Chemical synapse Stories
Like a gardener who stakes some plants and weeds out others, the brain is constantly building networks of synapses, while pruning out redundant or unneeded synapses.
Can the nerve signaling inhibitor tomosyn help retain long-term memory?
Scientists at Cold Spring Harbor Laboratory (CSHL) have solved part of a puzzle concerning the relationship between changes in the strength of synapses – the tiny gaps across which nerve cells in the brain communicate – and dysfunctions in neural circuits that have been linked with drug addiction, mental retardation and other cognitive disorders.
An ongoing lack of sleep during adolescence could lead to more than dragging, foggy teens, a University of Wisconsin-Madison study suggests.
Zinc plays a critical role in regulating how neurons communicate with one another, and could affect how memories form and how we learn.
The brain learns through changes in the strength of its synapses -- the connections between neurons -- in response to stimuli.
Nicolas G. Bazan, MD, Ph.D, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, and David Stark, an MD/Ph.D student working in his lab, have discovered how a key chemical neurotransmitter that interacts with two receptors in the brain promotes either normal function or a disease process -- determining whether brain cells live or die.
Researchers working with adult mice have discovered that learning and memory were profoundly affected when they altered the amounts of a certain protein in specific parts of the mammals' brains.
The crystal structure of the dynamin protein — one of the molecular machines that makes cells work — has been revealed, bringing insights into a class of molecules with a wide influence on health and disease.
A new tool allows scientists to see the immune system like never before.
