A NIRS sensor device for brain monitoring is small in size, provides reliable attachment to a patient, blocks ambient light, is easy to use, is hygienic, and supports data integration with surgical and monitoring systems. The sensor device is coupled to a remote near infrared light source via a hybrid cable. Since the light source is remotely located, a source adapted for providing high energy, short pulses can easily be used so that there is less chance of interference by superficial non-brain tissues and less interference from ambient light. In addition, the remote location avoids changes in output of local light sources experienced in the prior art during hypothermia procedures (e.g., bandwidth shifts in LEDs as a result of lowered temperature). The higher energy may be achieved by the use of laser diodes as opposed to locally-mounted LEDs typically used in the prior art. The sensor device is a two-piece design comprising a reusable portion containing the photodetector(s) and a disposable portion that receives the light from the reusable portion and bends it to direct the light into the brain.

A brain-machine interface for extracting user action intentions within a continuous asynchronous interactive environment is presented. A subliminal stimulus module generates contextually appropriate decision-related stimuli that are unobtrusive to a user. An altered perceptual experience module modifies a user's sensation of the interactive environment based on decision-related stimuli generated from the subliminal stimulus module. A brain monitoring module assesses the user's brain activity in response to the decision-related stimuli and to determine whether an action within the asynchronous interactive environment is intended by the user. Finally, an action is taken based on explicit user input, the user's brain activity in response to the decision-related stimuli, or a combination thereof. The decision-related stimuli can be visual stimuli, audio stimuli, tactile stimuli, or olfactory stimuli, any be a repeated signal having a start and a stop, where the start and stop are selected to minimize cognitive load on a user.
