NMDA receptor channels in excised outside-out patches from mature wild-type granule cells. Lefttraces illustrate representative examples of the conductance levels displayed by NMDA-activated channels in excised patches from four wild-type granule cells. Right graphs illustrate the amplitude–frequency histogram of a larger data set obtained from the patch shown to the left. Conductance levels in picosiemens for each patch reflect the estimated conductance after subtraction of junction potentials and estimation of the reversal potential (as in Fig. 2D).
