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 particular appropriate regions of the nervous system, thus su... Read More

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, when A is preferred to B, B to C, but C to A, there corresponds a ... Read More

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 capacity equals the maximum attainable im... Read More

Why the mind is in the head?

As the industrial revolution concludes in bigger and better bombs, an intellectual revolution opens with bigger and better robots. The former revolution replaced muscles by engines and was limited by the law of the conservation of energy, or of mass-... Read More

The brain as a computing machine

Electrical engineers distinguish between problems of strong currents - or power engineering - and of weak currents or communication engineering. Computing machines, including brains, belong to the latter specialty. Man's brain is much the most compli... Read More
