In epilepsy, the GABA and glutamate balance may be disrupted and a transient decrease in extracellular calcium occurs before and during a seizure. Flow Cytometry based fluorescence activated particle sorting experiments quantified synaptosomes from human neocortical tissue, from both epileptic and nonepileptic patients (27.7% vs. 36.9% GABAergic synaptosomes, respectively). Transporter-mediated...
