Because of the “all-or-none” character of nervous activity, neural events and the relations among them can be treated by means of propositional logic. It is found that the behavior of every net can… Expand

Neural events can be described by means of propositional logic, and it is shown that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes.Expand

Theoretically, it seems only natural that the filters estabINFORMATION in RANDOM NETWORKS 29 lished to begin with will res pond to a broad cross section of the environment.Expand
