Detailed balance; nonlinear dissipative systems; fluctuation-dissipation theorem.

We have explored the weak noise limit of stochastic processes in nonlinear dissipative systems which admit of stable dynamical attractors in absence of noise. An interesting `detailed balance’ like condition in the steady state which is manifested in the time reversal symmetry between growth and decay of fluctuation far from equilibrium, similar to what is observed in thermally equilibrated systems, is demonstrated.
