Abstract
A two-dimensional time-dependent Duffing oscillator model of macroscop ic neocortex exhibits chaos for some ranges of parameters. We embed th is model in moderate noise, typical of the context presented in real n eocortex, using PATHINT, a non-Monte-Carlo path-integral algorithm tha t is particularly adept in handling nonlinear Fokker-Planck systems. T his approach shows promise to investigate whether chaos in neocortex, as predicted by such models, can survive in noisy contexts.
