(A) Schematic representation of the experimental design. Thirty-two rats were divided into four groups of eight animals each. Each group received a respective stimulation protocol for 20 min under anesthesia. Electrophysiological recordings, including motor-evoked potential (MEP), input-output curve (I/O Curve), and long-interval intracortical inhibition (LICI), were measured pre-and post-stimulation. (B) The top view of the rat skull shows the positioning of epidural screw electrodes for stimulation and electrophysiological recordings. (C) A detailed diagram illustrates the electrode placements with specific coordinates on the skull over the targeted motor cortical region.
