Abstract:

The action of a Poisson flow of impulses on one synapse for the case of background activity is analyzed in the present study. According to the mediator theory of transmission of excitation through a synapse, each impulse arriving along the axon to the synapse is accompanied by secretion of a certain number of molecules of a chemical substance, the mediator, into the synaptic fissure. It is assumed that bundles of the mediator molecules represent uniformly distributed independent positive random values x with a distribution function Hx, and that the decomposition of the mediator is constant in time. Also, it is assumed that a local postsynaptic potential LPSP appears in response to each input impulse and the amplitude of the LPSP is proportional to mediator concentration in a synaptic fissure. After determining distribution function for the mediator concentration, it can be used to find the amplitude probability distributions of LPSP. Author
