According to the stereotaxic coordinates of the primary somatosensory cortex
(Bregma coordinates: 1.32-3.72 mm posterior, 5.0-5.5 mm lateral, and 1.8-3.4 mm depth; Charles and Watson George 6th, figure 1), the pyramidal neurons in layer IV of the primary somatosensory cortex
were selected with a BX51WI microscope (Olympus, Japan).

Previous studies have demonstrated changes in activity of the primary somatosensory cortex
(S1) and sensory perception of stimulated area; however, little is known about how the activity of the primary motor cortex (M1) and motor skills is changed.
