From experiences of medial amygdalotomy on epileptics.

This paper does not present any new cases. From the long-term follow-up study of the cases operated by the stereotaxic medial amygdalotomy, the progressive worsening in clinical pictures of the chronic epileptics, such as changes of pattern of seizures, aggravation of seizure tendency and of emotional and behaviour problems, were found to be parallelly improved. The reason of such beneficial changes is discussed and the possible participation of the limbic structures is suggested.
