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 described in these terms, with the addition of more complicated logical means for nets containing circles; and that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes. It is shown that many particular choices among possible…

The general conclusion is that with the special kind of experimental results usually available so far, it may often be better to use only hypotheses on the total behaviour of a neural subsystem, disregarding the details of the network producing that behaviour.
Nonmonotonic Inferences and Neural Networks

The main results are that certain activities of connectionist networks can be interpreted as non-monotonic inferences, and that there is a strict correspondence between the coding of knowledge in Hopfield networks and the knowledge representation in weight-annotated Poole systems.

A statistical mechanical problem?
In this paper it will be shown how, starting from very simple systems, connectivity engenders levels of increasing complexity in the functions of the brain depending on specific constraints.

Central Nervous System and Computation
The emerging picture shows the brain as a very peculiar system, in which genuine computational features act in concert with noncomputational dynamical processes, leading to continuous self-organization and remodeling under the action of external stimuli from the environment and from the rest of the organism.

This paper describes a more biologically-oriented process that could be used to build the sort of networks we associate with the human brain. A ‘refined’ neuron will be proposed that can process more
