S ummary 1. We have examined the EEGs from 51 epileptics to see if there is any relationship between paroxysmal dysrhythmia and the theta wave of the background activity and found that there certainly exists an antagonistic relationship between the two. 2. It has been ascertained that the theta wave of the background activity is closely associated with irritability and that the relationship between the theta wave and so‐called epileptic personality such as irritability is particularly noteworthy. 3. It has also been found that the frequency of appearance of the theta wave does not depend on the duration of epilepsy in the patient. 4. The foregoing results we have obtained have led to the conclusion that in epilepsy paroxysmal dysrhythmia stands in a homeostatic relation to the continuous theta wave of the background activity, and to a sort of psychic symptom such as irritability to be developed in the patient. 5. The clinical trait of epileptic, such as irritability, is to be considered not as a trait of an epileptic personality but as psychic symptom of epilepsy.
