Recording setup and stimulation protocol. A The location of craniotomies and recording electrodes in relation to different cortical areas. M1, primary motor cortex; S1, primary somatosensory cortex; A1, primary auditory cortex; V1, primary visual cortex. B The location of the tactile stimulation electrodes on the distal left forepaw and right hind paw. C Visualization of the stimulation protocol that was repeated before and after amphetamine administration. D ECoG traces before and after amphetamine administration, recorded from the right S1 area, with artifacts removed and Savitzky-Golay filter applied. The traces were recorded one minute before (top) and 15 min after the administration of D-amphetamine (bottom).
