Novel optogenetic implant controls activity of neurons in the spinal cord

Grégoire Courtine doesn't hesitate to use the word "revolutionary" when describing the emerging field of optogenetics – a technology that uses pulses of light to control individual neural activity – and what it could mean for neuroscience. Courtine, director of the NeuroRestore research center (with neurosurgeon Jocelyne Bloch), is currently developing an optogenetic implant together with Stéphanie Lacour, who holds the Bertarelli Foundation Chair in Neuroprosthetic Technology.

Novel system may enable noninvasive and more precise measurement of cerebral blood flow

In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, cerebral blood flow is considered a vital and sensitive marker of cerebrovascular function. Optical methods offer a noninvasive approach for measuring cerebral blood flow.
