Inward currents evoked by exogenous glutamate under ischemia conditions. A). A sample trace shows inward currents elicited by two applications of exogenous glutamate. The first application was made in normal bath solution and the second application was made 10 min following the perfusion of ischemia bath solution. An arrow indicates the start of the ischemia-induced inward currents. B). A sample trace shows inward currents elicited by two applications of exogenous glutamate in normal bath solution. C). Summary of the changes of glutamate-evoked currents in normal bath solution (first set of bars) and in ischemic bath solution (second set of bars). The current amplitudes were normalized. Open bars represent the currents evoked by the first application recordings of glutamate (n = 6); black bars represent the currents evoked by the second applications of glutamate (n = 6).
