Answer

Answer

For response acquisition, the clinician can choose to use only 1 channel to evaluate horizontal eye movements. However, a minimum of 2 channels is recommended; this facilitates evaluation of both horizontal and vertical eye movements. A 3-channel recording system further increases the power of analysis by allowing horizontal recording of each eye and vertical recording of one. Finally, some newer systems provide acquisition of both horizontal and vertical movements of each eye.
