Optical mapping of the internal signal is a unique method of studying the brain and makes it possible to investigate the functional anatomy of the cerebral cortex with high spatial resolution. Modern modifications of this method make it possible to shorten the time to obtain individual functional maps, and this opens up new prospects of using the given approach in neurophysiological experiments. It is shown to be possible in principle to use optical mapping of the internal signal to objectively test the visual function: As the contrast of the visual stimulus changes, changes have been observed in both the amplitude of the metabolic response in the cortex and in the structure of the functional maps.
