A device may obtain imaging data. The imaging data that is obtained depicts one or more body parts of a patient. A voltage sensitive dye may be applied to stain nerve tissue associated with the one or more body parts of the patient. The voltage sensitive dye may be activated by neuromodulation applied to stimulate the nerve tissue. The imaging data may capture a fluorescence of the nerve tissue based on the voltage sensitive dye being activated by neuromodulation. The device may provide the imaging data for display.

Neuromodulation based nerve identification

A device may include an image capturing component to obtain images of an environment of a user, and a light projection system. The light projection system may include a laser source and an optical imager. The device may process, in real-time, images captured by the image capturing component to derive signals for controlling the laser source, provide the signals to the laser source to enable the laser source to generate a laser beam pattern, cause the optical imager to raster scan the laser beam pattern to an absorptive element. The absorptive element may be disposed on or in the user, and positioned proximate to a region-of interest, of the user, that includes neuronal cells. The laser beam pattern may cause the absorptive element to produce acoustic energy that cause depolarization of the neuronal cells. The sensory stimulation may enable the user to visually and/or auditorily perceive the environment.
