Experiment example: Auditory vs Visual vs Motor stimulus
Author: Hadi Zaatiti <hadi.zaatiti@nyu.edu>
Description
In this experiment implemented using the Psychtoolbox framework, a random sequence of three stimulus is performed:
- an auditory stimulus with a 200 Hz audio of 500 ms duration
stimulate activity in the primary and secondary auditory cortex
a visual stimulus with a full field white flash appearing on screen, fixation cross maintained
Visual stimulus: full field flash black to white
such stimulus would stimulate the occipital visual cortex
- a motor stimulus requiring a button press
should stimulate the contralateral motor cortex
Every stimulis occurrence is spaced from the next one by an Inter-Stimulus Interval (ISI) randomly picked from 2 to 2.5 seconds (with 100 ms step size)
