Instability of Pulse Activity in a Net with Threshold.
Nature 196: 561–562.
Excerpt: For half a century, threshold has been known to be important in the activities of nerve cell and synapse, but little is known of the general properties that so ubiquitous a feature must impose on the system’s behaviour in the large. Beurle1, in his investigations of the transmission of waves of activity over a conducting not, noticed that a net with threshold would have a marked tendency to be unstable, but his assumptions were complex, and the origin of the instability is not easily identified. Here we propose to show that an instability, similar to his, can readily be traced from a simpler origin.
