Question

Answer 1

Answer #1

Ans) Eye movements are recorded during physiologic calibrations:

- The tasks allows the technique to verify all the signals are accurate.

- Sets parameters for the scoring tech.

- Close eyes- reveals alpha activity in the occipital EEG channels, Open eyes-alpha activity is eliminated.

- Look Left and Right - mimics REM, Look Up and Down- mimics N1 and helps differentiate between vertical and horizontal eye movements.

Experiments to study vision often need to track the movements of a subject's eye. One way of doing so is to have the subject sit in a magnetic field while wearing special contact lenses with a coil of very fine wire circling the edge. A current is induced in the coil each time the subject rotates his eye. Consider the experiment shown in the figure in which a 15-turn, 6.0-mm-diameter coil of wire circles the subject's cornea while a 1.0T...
