Fig. 6. Current traces showing that the reduction of glutamate-induced current
under continuous flow conditions is established rapidly. The glutamate-induced
current was produced repeatedly by 25 s applications of solutions containing
various concentrations of glutamate (numbers in the figure, µmol
l-1) to oocytes expressing NMDAR only (EAAT3- oocytes in
panel A) or co-expression oocytes (EAAT3+ oocytes in panel B).
