Focally evoked mEPSCs. A, Response to a single puff of Ba/K solution. The large inward current, which persists for several seconds after the puff, was attributable primarily to summation of AMPA receptor-mediated synaptic events, as it was greatly reduced by 5 μm NBQX (data not shown).Inset, Portions of the larger trace, from the areas indicated by letters, displayed on a faster time scale.B, Cumulative probability histogram of rise times of mEPSCs evoked at the soma (solid line;n = 341) or ∼150 μm out along a dendrite (dotted line; n = 363).Inset, Averages of events in both conditions.
