As an essay towards the determination of the effect of structural relations among nerve fibers upon the character of their activity, preliminary consideration is given to the steady-state activity of some simple neural structures. It is assumed as a

Continuing the investigation previously introduced, it is shown here that when the product of the activity parameters of the circuit is not exceeded by unity (algebraically) a steady state is not possible in which all fibers of the circuit are active

Conditions under which either of two distinct activity patterns may arise from the same stimulus pattern are deduced for the case of a net-work which consists ofN simple circuits all jointed at a common synapse. If the product of the activity paramet

The isometric length-tension diagram for individual fibers and for whole muscle is considered, and it is proposed that the tensionp may be represented for any muscle whose fibers are parallel and not in series, in the form $$p = f\left( x \right) + \

It is found that for a simple circuit of neurons, if this contains an odd number of inhibitory fibers, or none at all, or if the product of the activity parameters is less than unity, then the stimulus pattern always determines uniquely the steady-st

Conditions are determined under which a single self-exciting neuron can reach a state of permanent excitation, in the case that the neuron develops both an excitatory and an inhibitory substance as well as in the case that it develops only a single,

A patient with progressive supranuclear palsy demonstrated a region-specific decrease in T2 signal during high-field-strength brain magnetic resonance imaging. At autopsy the T2-signal hypointensity was found to correspond topographically to increase
