Functionally Specific Optical Stimulation of Brain Circuits

Save as calendar entry

Visual cortical prosthetics have been based on neural activation via electrical stimulation. Such approaches have evoked crude visual percepts of light (termed phosphenes) in monkeys and humans. As such percepts are relatively crude, these methods have failed to gain traction. A primary shortcoming of these designs was the failure to take advantage of inherent functional organization in the cerebral cortex. Here, I explore optical methods to stimulate known functional architectures in a targeted and selective way. Our evidence indicates that such stimulation achieves functional network-specificity and intensity dependence in a way that mimics visual stimulation. Application of this approach to known feature domains (such as color, orientation, motion, and depth) in visual cortex may lead to increased specificity and sophistication of visual cortical prosthetics.

Arrival by car

Leave the interstate A7 at exit "Göttingen Nord". Follow the B27 straight ahead in the direction of "Braunlage". After the third traffic light intersection turn right towards "Kliniken". Afterwards turn left onto "Robert-Koch-Straße" direction "Universität Nordbereich/Polizei". At the end of "Robert-Koch-Straße" turn right onto "Otto-Hahn-Straße", direction "Nikolausberg". The first street on the left turn onto "Kellnerweg", follow the signs "Deutsches Primatenzentrum".


Arrival by bus

The footpath from the bus stop "Kellnerweg" to the Main Entrance/Reception: 
From Bus stop "Kellnerweg" (line 21/22 and 23) Cross the road, go in the direction of the bus. At the mailbox, turn left into the footpath and proceed to the end. Turn right into the Kellnerweg. The main entrance of the DPZ is on the left side.
