We investigate the existence of a global attractor and itsupper semicontinuity for the infinite-dimensional latticedynamical system of a partly dissipative reaction diffusionsystem in the Hilbert space l2×l2. Such a systemis similar to the discretized FitzHugh-Nagumo system inneurobiology, which is an adequate justification for its study
