The decay kinetics of currents mediated by GluK2/K5 kainate receptors strictly depends on the length of glutamate pulse. (A) Representative traces of GluK2/K5 currents elicited by long (100 ms) and brief (1.5 ms) pulses of glutamate 1 mM. Please note that the current elicited by brief glutamate pulses (right panel) deactivates markedly slower that that obtained at long glutamate exposures (left panel). (B) Dependence of GluK2/K5 current deactivation kinetics upon glutamate pulse length. Modified from Barberis et al. (2008) with permission.
