Despite the advances of electrophysiology and the passage of fifty years, the conclusions of John Hughlings Jackson as regards the mechanisms involved in idiopathic epilepsy are today not only being confirmed, but are serving as a basis for farther investigation. Studies of cortical localisation of onset in various forms of epilepsy have failed to reveal a focus of onset for petit mal attacks. Major generalised convulsive seizures ("grand mal") of bilateral onset have also defied attempts at localisation at the level of the cortex.
