摘要：In this paper, we first consider the existence of random attractors for the non-autonomous stochastic lattice FitzHugh-Nagumo system with random coupled coefficients and additive white noise in a weighted space l ρ 2 × l ρ 2 $l_{
ho }^, imes l_{
ho }^, $ ; then we establish the upper semicontinuity of random attractors as the intensity of noise approaches zero.
