Overview of experimental setup and data acquisition process. (A) The experimental protocol comprises four task stages, each lasting 60 seconds. The illustrations provide a visual representation of the mouse’s behavior within the arena, which is segmented into the threat and safe zones. (B) The panel depicts the recording sites targeted for electrode implantation (left) and the diagram of our measurement device (right). The brain regions highlighted in blue mark the electrode tip locations, along with their anterior-posterior (AP) coordinates relative to the bregma. The electrodes, fixated in place with dental cement, were connected to the CBRAIN headstage device via an electrode-CBRAIN connector. Data transmission was achieved wirelessly through Bluetooth-enabled mobile-edge computing. The mouse brain atlas is taken from Paxinos and Watson’s book27. The image of a telemetry receiver dongle is provided by the courtesy of Nordic Semiconductor (https://www.nordicsemi.com). (C) The experimental conditions are outlined, differentiating between the solitary and group settings. In the solitary condition, a mouse interacts with a robot predator individually, whereas, in the group condition, a cohort of eight mice engage with the robot collectively.
