Information from different senses is integrated in the human brain. The purpose of this study was to examine how the activation in the human auditory cortex changes during audio-visual stimulus. Visual speech and nonlinguistic auditory stimuli were presented simultaneously and activation in auditory cortex was measured using functional magnetic resonance imaging (fMRI). The effect of soundless vowel production in mind was studied as well. In the experiment, two nonlinguistic auditory stimuli were presented at the middle frequencies 250 Hz (low) and 2 000 Hz (high). Duration of the tone was 100 ms and stimuli were repeated every 500 ms in 30-s periods. Low and high frequency tones and silent period were presented in random order. Vis...
