State the term - Focal Seizures

A focal seizure begins in one place and then spreads. As for example in a Jacksonian focal seizure, the attack begins with jerking movements in one part of the body (for example, a finger, a toe, or the mouth) and then spreads to adjacent parts. John Hughlings-Jackson hypothesized in 1870 that such seizures probably originate from the point (focus) in the neocortex representing the region of the body where the movement is first seen.
