  • Title: Gaze-evoked involuntary movements.
    Author: Sethi KD, Hess DC, Harbour RC, Holmes GL.
    Journal: Mov Disord; 1990; 5(2):139-42. PubMed ID: 2325675.
    Abstract:
    Voluntary gaze may evoke a number of neurological phenomena such as vertigo, tinnitus, blepharoclonus, eyelid nystagmus, "facial nystagmus," involuntary laughter, and seizures. We report two patients in whom eccentric gaze evoked facial twitching and arm movement. Electroencephalograms remained unchanged during these movements. The pathogenesis of these movements is unclear but may involve ephaptic transmission.
