Figure Lengend Snippet: ( A to D ) Schematic diagrams of the CBRAIN system. (A) Photo of a mouse wearing the 2.6-g-weight CBRAIN headstage. (B) A headstage consisting of an amplifier, edge computing processor, telemetry, and LEDs records, analyzes, transmits BLA signals, and reports the neural activity. A high-speed bird’s-eye view spectral camera records the group behaviors and LED lights. (C) The data acquisition software CBRAIN Studio synchronizes and records neural signals from multiple mice. (D) A schematic diagram of the experimental setup for CBRAIN. Here, the blue and red dots represent the tracking and the neuroreporting LEDs. ( E ) An example trace of the neural signal in the amygdala that contains gamma oscillations (top) and gamma oscillation detection by edge computing (bottom). ( F to H ) Example of CBRAIN neurolabeling data with trajectories. (F) Captured image frame with identity markers. (G) A frame of video with the trajectory and neuroreporting events provided by CBRAIN for eight mice over a period of about 1 s. (H) The trajectories and neuroreporting events for all mice over a 15-s time period. Photo credit: Nam Kyun Kim and Jisoo Kim, Korea Institute of Science and Technology.
Article Snippet: LFP recording was accomplished through the use of custom software, CBRAIN Studio, which is a graphical user interface (GUI) program built in MATLAB 2020a (MATLAB Inc. Natick, MA, USA).
