Latest Optogenetics 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.
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.
Optogenetics is a technique that allows scientists to control neurons' electrical activity with light by engineering them to express light-sensitive proteins.
A team of researchers has stumbled upon a way to stop binge drinking in animals using light stimulation of specific neurons.
Neuroscientists are eagerly, but not always successfully, looking for proof that optogenetics – a celebrated technique that uses pulses of visible light to genetically alter brain cells to be excited or silenced – can be as successful in complex and large brains as it has been in rodent models.

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.
With a few flicks of a light switch--on-off-on-off--Stanford University's Oscar Abilez is one step closer to changing the lives of millions.
Pressing the button of the lift at your work place, or apartment building is an automatic action – a habit.
