In the implementation of this study Chinese characters were used as a visual stimulus and for the auditory stimulus Chinese speech sounds were used, of which effects to the brain were observed by presenting the stimuli either unimodally or bimodally. Two groups of subjects were formed: Finnish subjects who did not know any Chinese and native Chinese subjects who also understood the meaning of the characters and speech sounds. This made it possible to also examine whether understanding the meaning of words made an impact on the processing of speech sounds and characters.\nThe brain activation was measured by 306-channel magnetic field-recording magnetoencephalogram, MEG. The localization of the brain activation was explored by BESA 6.1. software, Classical LORETA Analysis Recursively Applied (CLARA) - source localization. The brain activation of the Finnish and Chinese subjects were compared between different conditions. The results show that Finnish subjects\u2019 visual cortex activated more strongly than Chinese, when the visual stimulus was presented without the voice (V). When stimulus pairs (AV) were presented congruently or consistently, Finnish right and left fusiform gyrus was activated more powerfully than Chinese. A conclusion can be reached that the audiovisual processing in the brain functions in complex ways, and knowing the meaning of the shown stimuli can affect in which brain region or how powerfully the brain activates.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2023-03-24T07:16:55Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-03-24T07:16:55Z (GMT).
