Fig. 1. Simultaneous bioelectrical and video mapping method. (A) Arrangement of the cross-polarized camera setup and the electrode array on the intestine. Camera exposure is recorded along with the bioelectrical signals by the BioSemi ActiveTwo system for synchronization. (B) Flexible electrode array used for high-resolution (HR) bioelectrical mapping (16 × 8 configuration; 4 mm spacing). (C) Intestine as visible from the camera, placed over the flexible electrode array. LED, light emitting diode.
