随机共振理论在人体感知系统中的作用
Role of stochastic resonance theory in the human perceptual system
摘要
Abstract
Stochastic resonance(SR)is a phenomenon where noise enhances the response of a system,optimizing its ability to detect and process small input signals.SR occurs in nonlinear threshold systems when the threshold,signal,and noise are appropriately matched.The human perceptual systems of vision,hearing,and touch are typical nonlinear threshold systems and are closely related to motor control capabilities.SR plays a complex role in these perceptual systems,certain noise stimulation can improve the visual,auditory,and tactile systems,thereby enhancing gait variability,hand dexterity,balance function,and proprioceptive abilities.As an important component of clinical rehabilitation therapy,SR can aid in the recovery of motor control abilities by increasing the neural system's sensitivity to input signals.In the future,a deeper understanding of SR should be developed to establish it as a novel rehabilitation treatment method within clinical medical practice.关键词
