Topic: tactile detection

Research on conscious somatosensory perception has mainly relied on electrical stimulation. Here, we directly compare the event-related potentials evoked by tactile vs. electrical peri-threshold stimulation, using a matching task to control for post-perceptual processes. EEG was recorded while participants received either electrical pulses to the left median nerve (n=24) or tactile stimulation at the left index finger (n=25). To control for confounding processes, participants did not directly report their experience, but indicated via saccades whether they experienced a match or a mismatch bet
