[Laufberger's excitation theory].

The author gives an account of V. Laufberger's Excitation theory at the occasion of the 100th anniversary of his birthday. This work was published as a monograph in 1947 and contains many data which foresee the further development of neuro-sciences and other scientific disciplines. From a certain aspect it is more cybernetic than Wiener's "Cybernetics" published one year later. It applies in a genial way the principle of logical elements made up of binary functional elements, backfeeds, parallel organization of neuron networks, and memories based on so-called spinning excitations. It is the first modern model of cerebral activity. It combines within one system the neuron and psychic level of organization of the brain.
