currentsinbiology:Researchers demonstrate optogenetic stimulation of the brain to control painA new study by a University of Texas at Arlington physics team in collaboration with bioengineering and psychology researchers shows for the first time how a small area of the brain can be optically stimulated to control pain. Samarendra Mohanty, an assistant professor of physics, leads the Biophysics and Physiology Lab in the UT Arlington College of Science. He is co-author on a paper published online by the journal PLOS ONE. Researchers found that by using specific frequency of light to modulate a very small region of the brain called the anterior cingulate cortex, or ACC, they could considerably lessen pain in laboratory mice. Existing electrode based ACC stimulation lacks specificity and leads to activation of both excitatory and inhibitory neurons.
