摘要：
Stochastic resonance (SR) is a statistical phenomenon recently studied in rr wide range of non linear physical systems. According to SR, there exists nn optimal noise level for which the information content of weak sub-threshold signals cml he detected. This study investigated SR in the human visual system in terms of subjective capacity, to recognise patterns under optimal noise conditions to Establish the possibilities of fMR1 techniques in making results objective.
