Optogenetics:
Optogenetic fMRI
Category: Neuroscience
A combination of optogenetics and functional neuroimaging shows that fMRI data are a valid measure of neuronal activity.

Optogenetics controls brain signalling and sheds light on Parkinson's therapy
Category: Neuroscience
Optogenetics is a newly developed technique based on a group of light-sensitive proteins called channelrhodopsins, which were isolated recently from various species of micro-organism. Although relatively new, this technique has already proven to be extremely powerful, because channelrhodopsins can be...

Optogenetic therapy for spinal cord injury
Category: Neuroscience
Optogenetics is a recently developed technique based on microbial proteins called channelrhodopsins (ChRs), which render neurons sensitive to light when inserted into them, thus enabling researchers to manipulate the activity of the cells using laser pulses. Although still very new...

Neuronal light switches
Category: Neuroscience
The September issue of Scientific American contains an excellent and lengthy article about a state-of-the-art technique called optogenetics, by molecular physiologist Gero Miesenböck, who has been instrumental in its development. As its name suggests, optogenetics is a combination of optics...

Channelrhodopsin restores vision in blind mice
Category: Neuroscience
New research shows that a protein found in green algae can partially restore visual function when delivered into the retina of blind mice, taking us one step further towards genetic therapy for various conditions in which the degeneration of retinal...

Control of rodent motor cortex with an optical neural interface
Category: Neuroscience
This year, several research groups have used bacterial proteins called channelrhodopsins to develop a technique with which light can be used to control the activity of nerve cells or the behaviour of small organisms. For example, Ed Boyden's group at...
