Overview of the CBRAIN system for monitoring brain activity in a group of mice

Caption

(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.
