Ketamine, phencyclidine, and MK‐801 protect against kainic acid‐induced seizure‐related brain damage

DB Clifford, JW Olney, AM Benz, TA Fuller… - …, 1990 - Wiley Online Library
Recent evidence implicates the endogenous excitotoxin, glutamate (Glu), in several neurologic
disorders, including seizure‐related brain damage. Ketamine, phencyclidine, and MK‐…

Glutamate transporters and retinal excitotoxicity

Y Izumi, K Shimamoto, AM Benz, SB Hammerman… - Glia, 2002 - Wiley Online Library
