Tissue-specific syntaxin-3 conditional KO mice do not decrease in basal synaptic transmission. Schaffer collateral axonal fibers were administered two successive stimulations from 10 to 150 µA and the resulting local fEPSPs from apical dendrites of CA1 pyramidal neurons were recorded. (a,b) Averaged traces of dendritic fEPSPs from syntaxin-3 flox/flox (control) (a) and syntaxin-3 flox/flox; CaMK2a-Cre (cKO) (b). (C and D) fEPSP amplitudes (c) or slopes (d) were plotted against presynaptic fiber volley amplitudes. (E and F) Paired-pulse ratios of amplitudes (e) or slopes (f) were plotted against presynaptic fiber volley amplitudes. Error bars indicate SEM (animal: n = 16 for control and n = 11 for syntaxin-3 cKO groups).
