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)
