Summary 1. The temporal lobe status appears at a rate of once every 3–5 minutes. 2. The duration of a single temporal lobe seizure is varied, ranging from 10 seconds to 140 seconds. 3. The EEG during seizures is characterized by a generalization of 15–32 Hz recruiting epileptic rhythm which may become 3–7 Hz slow waves later in some cases, 3–7 Hz paroxysmal rhythmic waves. 4. The clinical symptoms are colorful, including apnic seizures, verbal automatism, alimentary automatism, gestural automatism, facial muscle twitching, versive seizure and tonic seizure. The clinical symptoms depend on the size and depth of focus and the scope of propagation of discharges. 5. Generalization cannot be attained merely by the firing of focus that has been formed secondarily. The firing of primary focus is indispensable as the condition for generalization. 6. The focus depends more on the time of the disappearance of discharges than on the site of the primary onset of paroxysm. Particularly important is the length of duration of ictal discharges. 7. The cortico‐cortical synapse and the cortico‐subcortical pathways were considered the sources of epileptic propagation.
