GluR4(i) single channels and amplitude histograms.A, Baseline noise and single-channel responses elicited by kainate, AMPA, and glutamate in GluR4(i)-containing patches. A channel-like event superimposed on the kainate-induced noise can be seen in the second trace. The dashed lines indicate the approximate size of the conductance levels activated by AMPA and glutamate as determined from time-course fitting (see B, C). The holding potential was −80 mV in each case. B, Amplitude histogram generated by time-course fitting of AMPA-activated events. The distribution was fitted to three Gaussian components, which gave mean conductance levels of 6, 16, and 27 pS. C, Amplitude histogram generated by time-course fitting of glutamate-activated events. The distribution was fitted to three Gaussian components, which gave mean conductances of 8, 15, and 24 pS.
