Latest Channelrhodopsin Stories
Scientists have bioengineered, in neurons cultured from rats, an enhancement to a cutting edge technology that provides instant control over brain circuit activity with a flash of light.
Nearly a decade ago, the era of optogenetics was ushered in with the development of channelrhodopsins, light-activated ion channels that can, with the flick of a switch, instantaneously turn on neurons in which they are genetically expressed.
Networked nerve cells are the control center of organisms.
With the flick of a light switch, researchers at the Salk Institute for Biological Studies can change the shape of a protein in the brain of a mouse, turning on the protein at the precise moment they want.
Researchers have isolated the neurons responsible for determining whether or not exerting effort in order to complete a task is worth the energy -- a discovery which could help medical professionals better deal with depression and other brain-related disorders.
A new technique that stimulates heart muscle cells with low-energy light raises the possibility of a future light-controlled pacemaker, according to this study.
Researchers at the medical university Karolinska Institutet have created a genetically modified mouse in which certain neurons can be activated by blue light.
New tools show potential for treating brain disorders.
