flexDrive

The flexDrive is an implant for chronic extracellular electrophysiology.

The design is miniaturized yet simple and can be used to independently position 16 electrodes with up to 64 channels in a package that weighs approximately 2g. The device is easy to build and accommodates arbitrary spatial arrangements of electrodes. Multiple optical fibers can be integrated into the recording array and independently manipulated in depth. The design enables precise optogenetic control and highly parallel chronic recordings of identified single neurons throughout neural circuits in animals as small as mice.
