Ultrafast Pulses Coherently Control Function in a Living Cell

Facebook Twitter LinkedIn Email Comments
Researchers have used light to excite a light-sensitive channel in the membrane of optogenetic mouse neurons. When the channels were excited, they allowed ions through, which caused the neurons to fire. The researchers say the same technique could be used on cells that are naturally responsive to light, such as retina cells. Previous research has demonstrated the use of coherently controlled light beams to regulate chemical reactions, but according to the University of Illinois team, their study is the first to use coherently controlled light pulses to demonstrate how living cell...Read full article
