The objective of this study was to examine whether the brain\u2019s automatic change-detection mechanism reacts to deviant stimuli differing from the repetitive standard stimuli in location and intensity in the somatosensory modality in healthy participants aged 19-58 years. During the study the participants watched a mute film and got electrical pulses on their fingers. In the intensity experiment, stimuli differing in intensity were presented with an inter-stimulus interval of 390-490 ms to the forefinger. In the location experiment, the stimuli were presented to the little finger and index finger with the same intervals as in the intensity experiment. The participants were informed not to pay attention to the electrical pulses. The pulses were given in a random order, 86 % of the stimuli being standard and 14 % deviant stimuli. We analyzed the MMR using mean amplitude values at 150-190 ms time window. The results showed that the responses to deviant stimuli differed from the responses to standard stimuli in the location experiment. This indicates an automatic change detection in the somatosensory modality, which is the counterpart to mismatch negativity in the auditory and the visual modalities. No MMR was found for the intensity changes.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-04-20T05:31:19Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-04-20T05:31:19Z (GMT).
