[Determination of the quantity of useful information in the spike responses of nerve cells]

The new method for quantitative estimation of useful information in the nerve cells responses is suggested. This modification of Charkevich method is based on the calculation of aposterior probabilities of events. The method is applied for the calculation of amount of useful information in the nerve cells responses. It is shown that the quantity of useful information in the nerve cells responses is increased in the course of adaptation processes.
