Abstract

Agents with the potential to induce seizure-like discharge in the limbic system also have the potential to induce permanent alteration in that system. The most dramatic set of alterations have been called, collectively, the kindling effect (Goddard, McIntyre & Leech, 1969). Kindling is observed when an agent is applied mildly, repeatedly, usually once per day, and the response to that agent progressively changes until it includes a major clinical convulsion. If the treatments are discontinued, the system does not return to normal, but remains in a state of readiness even for a year or more. It will respond with convulsions to unusually low doses or gentle application of a wide range of the known epileptogenic agents (Pinel & Van Oot, 1976). When sufficient time is allowed between treatments, the sensitivity of the convulsive response may continue to increase; and, in some cases after many repetitions, the convulsions may recur spontaneously (Wada, Sato & Corcoran, 1974; Wada, Osawa & Mizoguchi, 1976; Pinel, Mucha & Phillips, 1975).
