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

Figure 2

Short- and long-term plasticity in response to -only and γ-only stimulation. (a) Representative example of response to -only protocol averaged over the total of 10 stimulations. (b) Cumulative data of EPSP amplitude ratios relative to first peak in train ( cells). Open symbols: individual experiments. Solid symbols: averaged data. (c) Same as in (a) but for γ-only protocol. (d) Same as in (b) but for γ-only protocol. Cumulative data of EPSP amplitude ratios relative to first peak in train ( cells). (e, f) EPSP amplitudes of individual long-term experiments with induction responses shown in (a) and (c), respectively. Cumulative data for both -only and γ-only data sets are shown in Figure 4(a). (e) -only. Control mean 7.5 mV; long-term mean 8.1 mV (dashed lines). (f) γ-only. Control mean 15.1 mV; long-term mean 13.0 mV (dashed lines).
