Simulation of the Neural Response in the Peripheral Auditory System

摘要: Response area, inhibitory and the phenomenon of masking in peripheral auditory system was simulated by computer model basilar membrane nervous connection. Assuming that primary neuron provides forward lateral inhibition input signal to changes proportion amplitude vibration membrane, internal potential neuron, n(x,f,I), is given n(x,f,I) = A⋅g(x,f,I) − ΣA⋅g(x + NΔx,f,I)⋅wi(NΔx), where wi represents distribution along x. If threshold θ, response area corresponding distance x0 will be expressed I = θ/A⋅{g(x0,f,1) − Σg(x0 + NΔz,f,1)⋅wi(NΔx)}. In presence second stimulus, similarly, which characteristic frequency f1 represented I2(f2) = {I1⋅n(x0,f1,1) − θ}/n(x0,f2,1). The computed results for these models agreed with observations on physiological experim...
