1. In monkeys, the stimulation of the Area 4, 3-1-2 produced a focal epileptic seizure of which initial convulsion was determined by the site of stimulation within the areas.
2. On the contrary, the stimulation of the Area 6 produced the generalized epileptic seizure from the beginning, but it produced a focal one, when a point of the Area 4 was preliminarily stimulated with subliminal strength for the seizure or when a sensory nerve of body was stimulated.
3. During epileptic seizure which was produced by the stimulation of the motor or the extramotor cortex, when a part of the motor area (Area 4 in monkeys) was extirpated, the seizure was not changed, nor ceased, but the extirpation of the whole Area 4 made the seizure stop at once.
4. If the above results are related as a form of law, the first law is “the law of initiation and continuation of epileptic seizure from motor cortex”. The second one is “the law of final common area for epileptic seizure from motor cortex”. The third law is “the law of substitution of cortex for epileptic seizure”. And the fourth law is “the law of pointing action of the motor area for the epileptogenic mode from the extramotor”.
