Patent ID: 7004912

Claim:
A system for identifying deficiencies, inefficiencies, or both, in neuronal interactions of a person's visual cortex, the system comprising: a) a processor; b) an image generator coupled to the processor, c) the processor and image generator configured to generate visual stimuli comprising arrangements of one or more target images each flanked by one or more flanking images of similar configuration as the respective target image, each arrangement designed to induce a level of neuronal facilitation and suppression in a person's visual cortex, the arrangements comprising a parameter of the one or more target images and the respective flanking images; and d) an input device coupled to the processor, the input device configured to receive the person's responses to the visual stimuli, the responses indicating detection or discrimination by the person of the one or more target images of the respective arrangements; e) the processor and image generator configured to generate at least some of the visual stimuli based at least in part upon the person's responses to previous visual stimuli, the at least some visual stimuli designed to induce differing levels of facilitation and suppression in the person's visual cortex; f) the processor and image generator being configured to generate sufficient visual stimuli of differing levels of facilitation and suppression in the person's visual cortex until responses to a sufficient number of facilitation and suppression levels are received from the person such that deficiencies, inefficiencies, or both, in neuronal interactions of the person's visual cortex may be identified by comparing a function of the person's responses to a normative response function of persons without known vision deficiencies.
