Interactions of Deep Structures during Seizures in Man

  • Mary A. B. Brazier

Abstract

The question raised at this symposium relates to the mechanisms by which electrical seizure discharge spreads within the brain and to the question whether any of this spread merits the name of “synchronization” in the absolute meaning of the word. Exact synchrony would demand either that the underlying neuronal mechanism be by volume conduction or that a single deeply situated trigger zone could activate many regions of the cortex, even in the two hemispheres, through fibre tracts and synaptic relays having precisely the same rate of conduction.
