Exploring long-range communications in the brain
March 23, 2016

Red and green dots reveal a region in the brain that that is very dense with synapses. A special fluorescent protein allows Dr. Ofer Yizhar and his group to record the activity of the synapses. (credit: Weizmann Institute of Science) Weizmann Institute of Science researchers have devised a new way to track long-distance communications between nerve cells in different areas of the brain. They used optogenetic techniques (using genetic engineering of neurons and laser light in thin optical fibers to temporarily silence long-range axons, effectively leading to a sustained “disconnect” between two distant brain nodes. … more…
