>Dr. Korvenoja: Hope you are enjoying the meeting. A very interesting poster. Was suppression of the gradient switching acoustic noise sufficient in order not to influence the stimulation by sound?
The suppression was clearly not sufficient to prevent stimulation by gradient switching noise. The background noise remains constant in all conditions, however. The auditory stimuli to be attended were delivered during the silent periods between image acquisition to prevent interfence of the scanner noise.
