The Frank lab and Deisseroth lab came out with a smart design for a movable optical fiber + tetrode (“optetrode”) drive. The design and fabrication of the drive, which can be assembled in less than 3 hours once you have all the parts, are exposed in a Nature Neuroscience technical report and will soon be posted here on OpenOptogenetics. The drive’s essential features are the following: compact, robust, lightweight (2 g) and low-cost. Stay tuned!
