Trains of Epidural DC Stimulation of the Cerebellum Tune Corticomotor Excitability
Figure 5
Effects of direct current stimulation (DCS) on afferent inhibition in left gastrocnemius muscle (a) and right gastrocnemius muscle (b) at baseline, after application of anodal DCS (ADCS) and cathodal DCS (CDCS) over left cerebellar hemisphere. A conditioning stimulus is applied on the sciatic nerve contralaterally to the stimulated motor cortex (right motor cortex and left motor cortex for (a) and (b), resp.) with an interstimulus interval of 45 msec. The afferent inhibition is expressed in % of baseline motor responses (obtained without conditioning stimulus). Mean values of motor evoked responses obtained in the baseline condition are set at 100% for each motor cortex. Mean values (filled circles; ±SD) as well as individual values (open circles) are shown. Cerebellar ADCS enhances the afferent inhibition for the ipsilateral muscle. ( rats).
