A logical calculus of the ideas immanent in nervous activity
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 be describe...

Chapter
Of Digital Oscillators
I want to talk about neurons, which I hold to be coupled nonlinear oscillators. Unfortunately, I lack the mathematics to handle them. Van der Pol (personal communication) opined that whether an ocean of them, ...

Control of Posture and Motion
While my interest in the functional organization of the nervous system for the control of posture and movement sprang from the study of its diseases in neurological patients, my experiments and those of my num...

Logisticon
Any logical function of n arguments can be represented by a single Venn diagram, each of whose spaces contains a 0 or 1 in Boolean fashion. Using 1 for true and 0 for false they constitute the truth table of t...

The Imitation of One Form of Life by Another—Biomimesis
I would like first to place bionics in a broader framework because there are several fields of interest which surround it on all sides. I therefore pick for my title “The Imitation of One Form of Life by Anoth...

The limiting information capacity of a neuronal link
The maximum rate at which a synaptic link could theoretically transmit information depends on the type of coding used. In a binary modulation system it depends chiefly on the relaxation time, and the limiting ...

Effects of Intraventricular Acetylcholine, Cholinesterase, and Related Compounds in Normal and ‘Catatonic’ Cats
IT has been known for some time that di-iso-fluorophosphonate and similar drugs, which are anti-cholinesterases in nature, in toxic doses produce syndromes resembling certain psychoses, and that in schizophrenics...

How we know universals the perception of auditory and visual forms
Two neural mechanisms are described which exhibit recognition of forms. Both are independent of small perturbations at synapses of excitation, threshold, and synchrony, and are referred to partiular appropriat...

A heterarchy of values determined by the topology of nervous nets
Because of the dromic character of purposive activities, the closed circuits sustaining them and their interaction can be treated topologically. It is found that to the value anomaly, whenA is preferred toB,B toC
