(a, b) 3D-printed electrode placement schemes. Tips of two recording electrodes were placed on the dorsal part of the zebrafish for EEG recording while a recording electrode was placed on the ventral part for ECG recording. Reference electrodes were placed on supraneural spine and belly for EEG and ECG recordings, respectively. (c) Photograph of the 3D-printed bioelectric sensor.
