Research Abstract

To develop a method of extract magnocellular (M) and parvocellular (P) components from VEP, the nonlinear system identification method using pseudorandom binary sequence (PRBS) stimulation combined with swept parameter technique was suggested and its efficacy was confirmed by experiments with healthy adult participants. The suggested technique would be effective for studying and screening several eye and neurocognitive disorders which have been reported to relate with selective damage in M/P pathways.
