Latest Optogenetics Stories
Swiss scientists were able to track the chemical signals neurons send to each across junctions called synapses by using a combination of genetic and light techniques – called “optogenetics”.
When we want to listen carefully to someone, the first thing we do is stop talking.
When investigators applied light-driven stimulation to nerve cells in the brains of mice that had suffered strokes several days earlier, the mice showed significantly greater recovery in motor ability than mice that had experienced strokes but whose brains weren't stimulated.
Researchers of the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden report how they managed to capture detailed three-dimensional images of cardiac dynamics in zebrafish.
Institute for Basic Science (IBS), the main organization of the International Science and Business Belt project in South Korea, has announced that a group of researchers, led by professor Won Do Heo, have developed a new technology in the field of optogenetics that can remotely control specific receptors by light.
A new study is focusing on the manipulation of memory in the hopes that cognitive diseases can be identified and treated. As is the case with many brain studies, the subjects the researchers are focusing on are genetically engineered rats.
A joint collaboration between the Vienna University of Technology and US researchers, has resulted in the development of a unique and novel technique to control Drosophila melangogaster, perhaps better known as the fruit fly, via thermogenetic means.
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.
In a study published in the April 6 online edition of the journal Nature, a team of Columbia University Medical Center researchers led by Ellen Lumpkin, PhD, associate professor of somatosensory biology, solve an age-old mystery of touch: how cells just beneath the skin surface enable us to feel fine details and textures.
