A method and an apparatus are described for simultaneously assessing the functional status of component parts of the nervous system by presenting sparse stimuli to one or more parts of the sensory nervous system. Sparse stimuli consist of temporal sequences of stimulus conditions presented against a baseline null stimulus condition, where the non-null stimulus condition, or conditions, are presented relatively infrequently. The low probability of encountering a stimulus differing from a baseline or null stimulus condition in sparse stimulus sequences insures that gain control mechanisms within the nervous system will increase the neural response magnitude and also bias the measured responses to those neurone populations having such gain controls. The consequently increased response amplitudes ensure more reliably recorded responses than are obtained with non-sparse stimuli.
