[Stochastic oscillations in a dynamic system modeling macroscopic activity of neuronal tissue].
A stochastic behaviour can be exhibited by dynamic systems with a simple organisation and in which the sources of uncontrolled noises are absent. This is the case of the system Zk+1 = (1 + exp (V-HZk))-1(mod I) which differs from Amari system suggested for description of macroscopic activity of neuron nets by addition of the term mod I with I less than 1. We have found that the sequence Z1, Z2, ..., Zk, ... corresponds to the oscillations of the postsynaptic potential of excitatory neurones and operation mod I is due to regulation functions of the inhibitory ones.
