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… 
Neurodynamics—An approach to theoretical neurophysiology
TLDR
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
TLDR
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.
Issues in the Mathematical Modeling of Cortical Functioning and Thought
In the last few decades, there has been an explosion of research on models of the cortex and how intelligent behavior might be achieved on the basis of these models. But to even start modeling in
Gossiping Nets
TLDR
The now established research discipline of Neurocomputing continues to have strong influences from electrical engineering, mathematics, computer science, psychology, neurobiology, and physiology.
A plausible method for assembling a neural circuit for decision-making
Gossiping Nets ✩
TLDR
The now established research discipline of Neurocomputing continues to have strong influences from electrical engineering, mathematics, computer science, psychology, neurobiology, and physiology.
Central Nervous System and Computation
TLDR
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.
Emergence in the central nervous system
TLDR
It is argued that possession of this property of some neural circuits throughout the CNS can result in profoundly altered neural dynamics on multiple levels in cortex and other systems.
The Re ( de ) fined Neuron
TLDR
A ‘refined’ neuron will be proposed that can process more variable sets of values, but with the same level of control and reliability that a binary neuron would have.
REASONING WITH ASSOCIATIVE MEMORIES
Reasoning is, undoubtedly, an important biological activity. Emerged at some point of biological evolution, reasoning is a neural function with a decisive role for the kind of life style that the
