L-glutamate (glutamate) is an important neurotoxin as well as the major excitatory neurotransmitter. Extracellular glutamate levels are elevated following ischemia, hypoglycemia, and trauma. One consequence of elevated glutamate levels is cell swelling. Such swelling occurs primarily in astroglial cells. We characterized the regional difference in(More)
