In the method and apparatus for assessing neural integrity of a patient's central nervous system, the patient is stimulated with a visual or auditory flickering stimulus, and oxygenation in the patient's second eye is sensed. Finally, the method and apparatus detects whether a change in the sensed oxygenation occurs in response to stimulation of the patient with the visual or auditory flickering stimulus. This change in the sensed oxygenation is indicative of neural integrity of the patient's central nervous system.
A method of treating visual system disease is disclosed. One embodiment comprises the steps of (a) exposing a component of a patient's visual system to light treatment, wherein the light treatment is characterized by wavelength of between 630-1000 nm and power intensity between 10-90 mW/cm.sup.2 for a time of 1-3 minutes, and (b) observing restoration of visual system function.
A system and method allow for inducing and measuring a consensual pupillary response of a subject. The system includes an induction device and a measuring device, the induction device being structured to generate at least one stimuli and to expose a primary eye of the subject to the stimuli. The measuring device of the system includes a monitoring mechanism structured to allow a consensual pupillary response to be detected, and an analysis mechanism to interpret the detected consensual pupillary response. The measuring device may also include a recording device and a display device, to allow recording and displaying of the detected consensual pupillary response, respectively. The method includes exposing the primary eye of the subject to the stimuli, monitoring and detecting the consensual pupillary response in the secondary eye of the subject, and analyzing the detected consensual pupillary response. The method may also include recording and displaying the detected consensual pupillary response.

A method of measuring the stress or relaxation level of a mammal and a method of measuring the activity of the sympathetic nervous system of a mammal by measuring quantititative levels of deoxyhemoglobin and oxyhemoglobin are disclosed. Preferably, the levels of deoxyhemoglobin and hemoglobin are measured by a noninvasive technique, such as spectroscopy. A method of changing the activity of the sympathetic nervous system of a mammal is also disclosed, wherein the method includes a step of administering an effective amount of sensory regimen to the mammal. The method is useful for humans who are operating vehicles or machinery, who are suffering from cardiovascular disease or related complications, who are pregnant, or who are preparing for sleep. In addition, a method of improving the complexion of the skin of a mammal is disclosed.
