Sniff-Like Patterned Input Results in Long-Term Plasticity at the Rat Olfactory Bulb Mitral and Tufted Cell to Granule Cell Synapse

Figure 4

Synopsis of plasticity experiments. SBS plasticity is NMDAR-dependent. Bottom: temporal sequence of induction protocol, number of experiments, average long-term plasticity (mean LT), and average efficiency of long-term plasticity induction (ΔLT, absolute value of plastic changes). All data ± SD. (a) Cumulative display of mean long-term change for all induction protocols with individual data sets, means (dotted lines), and SD (extent of grey bars). (b) Mean long-term change of SBS experiments in the presence of 25 μM APV. Note the substantially reduced variance. (c) Mean long-term change of experiments without induction ( = 11: 5 without induction and 6 recorded from heteroglomerular control channel that was not induced with SBS; see Figure 5).
