Example of multi-channel time course data recorded by CIGAL during a fMRI scan
The paradigm was a visually guided saccade task with central fixation and saccades to and from eccentric targets (1 Hz). The bottom black ticks indicate the time of each MR image acquisition (14 interleaved slices), the lower green trace is skin conductance sampled by A/D at 100 Hz. Heart beat (red) and respiration (blue) were recorded from scanner transducers via streaming serial port input (80 Hz). The horizontal displacement of saccade targets is shown in orange with a green trace superimposed of horizontal eye position recorded via streaming serial port input from a separate eye-tracking computer (30 Hz). The upper blue curve shows the timing of targets expecting button presses, and the black tick marks above the curve shows the identity and timing of the button responses. CIGAL can routinely record and display behavioral and physiological data like this for any paradigm with no programming required by the user.
