[The role of the temporal neocortex in the origin of convulsive activity].
Experiments on cats with cooling capsules implanted over different areas of the neocortex have shown that cooling of different intensity applied to the temporal neocortex may result in both stimulation and switching off effects. Cold stimulation (temperature dropping to 27-33 degrees C) manifested in generalized epileptiform brain electrical activity and paroxysmal states. The functional switching off the temporal area observed during its deeper cooling (20-21 degrees C) discontinues the paroxysmal state already developed and prevents the appearance of seizures, regrardless of the localization of the epileptogenic focus. The paroxysmal state weakens and ceases after repeated cooling of the temporal neocortex. The temporal neocortex, involved in the integrated activating brain system, plays a decisive role in the emergence of paroxysmal states.
