Summary: The authors hypothesize that loss of inhibition from the cerebellum can lead to cortical activation and seizures. An animal study showed microinjection of SSP-SAP produced a selective ablation of hippocampal inhibitory interneurons in vivo and a highly focal disinhibition. These results also demonstrate that the ‘‘epileptic” pathophysiology produced by experimental status epilepticus or head trauma can be replicated by focal interneuron loss, without involving principal cell loss and other interpretive confounds inherent in the use of global neurologic injury models.
