[Cerebellar cortex: simulation of recurrent collateral inhibition by means of a neuronal automata assembly. II. Temporal modulation and informational content].

A quantitative evaluation of the information content exhibited by a neuronal automata assembly coupled by collateral inhibitory--type rules was undertaken on the results of a computer simulation of this partial model of the cerebellar cortex. By comparison with an uncoupled array the model exhibited two main properties: A markovian type of behavior appears in the functioning of the system in as much as the appearance of a given state is strongly and exclusively correlated to the immediately preceding one. This behavior leads to a decrease in the entropy of the system. This implies that the informational content of the efferent "activity" is significantly higher than that of the afferent one.
