Latest Optogenetics Stories
With the novel use of a technique that uses light to control brain cells, Stanford University researchers have shown that fragmented sleep causes memory impairment in mice.
Recently, optogenetics, which controls the activity of neuron using the light-activated protein, has been getting a lot of attention.
Unlike conventional methods, with the so-called optogenetics, the researchers are able to target one cell type.
Using a combination of genetic engineering and laser technology, researchers at the University of North Carolina at Chapel Hill have manipulated brain wiring responsible for reward-seeking behaviors, such as drug addiction.
Commenting on Edward Boyden's article, Ben Barres, Head of the Neuronal & Glial Cell Biology Section of Faculty of 1000 and Professor at Stanford University School of Medicine said: "There will probably be a Nobel prize for optogenetics someday as it has revolutionized our attempts to understand how the brain works.
A new study sheds light--both literally and figuratively--on the intricate brain cell connections responsible for anxiety.
Stimulation of a distinct brain circuit that lies within a brain structure typically associated with fearfulness produces the opposite effect: Its activity, instead of triggering or increasing anxiety, counters it.
'Out of the blue' discovery marks new direction in phototransduction studies.
Physicists and bioengineers have developed an optical instrument allowing them to control the behavior of a worm just by shining a tightly focused beam of light at individual neurons inside the organism.
Researchers are using inexpensive components from ordinary liquid crystal display (LCD) projectors to control the brain and muscles of tiny organisms, including freely moving worms.
