Experiments were made on somatic areas I and II of the unanesthetizedcat to produce the flexion of contralateral forepaw by electrical stimulation. Insomatic II, there was little evidence to support Garol and Woolsey's results (6, 10), since the flexion limited to contralateral forepaw could be produced fromany point in this area. Between somatic I and II, no remarkable difference wasrecognized in threshold value of motor response ; influence of duration of singlepulse upon threshold of motor response ; latency before the appearance of motorresponse ; influence of varying interval between two pulses upon character ofmotor responses. Moreover, the phenomenon of summation was recognized oneach or both somatic I and II.
