A method for switching neurons on and off with light helps pinpoint anxiety neurons in the brain

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

Targeting axons uncovers the brain's distance communications
