The video bj-full-120fps.mp4 serves as a demonstration of the system's architecture, which integrates:
The system operates on a dual-camera setup. A wide-angle camera maintains a lock on the fly's global position within the arena, while a second, high-magnification camera targets specific anatomical regions. By utilizing Thorlabs 2D galvanometers, we can steer a laser to deliver precise optogenetic or thermogenetic stimulation—all while the fly moves freely.
: 2D galvanometers used to aim lasers at specific body regions of freely walking flies.
: Image results and targeting calculations performed at 120 frames per second (fps).
: Built using Python and the Robot Operating System ( ROS ) for interprocess communication. 📝 Blog Post Draft: Mastering Real-Time Neural Control
The primary language for our tracking and targeting logic. OpenCV: Utilized for high-speed computer vision.
In the world of neurogenetics, timing is everything. To understand how specific neurons drive behavior, researchers
