Fig. 9. ΔRR protected neurons exhibit normal field EPSPs and paired pulse ratios.
OHC were infected with ΔRR and/or treated with KA as in Fig. 3B. At 72 hrs after initiation of KA treatment field excitatory postsynaptic potentials (fEPSP) were recorded in the stratum radiatum in response to granule cell stimulation as described in materials and methods. The fEPSP amplitude and paired pulse ratios were expressed as the mean ± SEM. Paired pulse ratios for cultures given KA alone could not be calculated due to the absence of fEPSP amplitudes.
