In MC simulation we follow the time dependence of a model for whichchanges proceed in a stochastic manner. It depends on sequence of random

numbers. The random numbers are generated during Monte Carlo simulation.

Stochastic resonanceIn biological systems, introducing stochastic 'noise' has been found to help improve the signal strength

of the internal feedback loops for balance and other vestibular communication.
