Figure 7. Regional differences of synaptic potentials in the mPFC.

Figure 7

Examples of extracellular field and synaptic activity recorded from presumed RS cells in PrL (A) and DP (B) during Cb–KA-evoked oscillations. Aa and Ba, 1 s example trace of extracellular field recording. Ab and Bb, 1 s epochs of EPSPs recorded at a membrane potential of −70 mV. Phase coherence histograms (bin size: 10 deg) between field and EPSPs in PrL (C) and DP (D) show low coherence. Different examples of extracellular field and synaptic activity recorded from presumed RS cells in (E) PrL and (F) DP during Cb–KA-evoked oscillations. Ea and Fa, 1 s example trace of extracellular field recording. Eb and Fb, 1 s epochs of IPSPs recorded at a membrane potential of −30 mV. Phase coherence histograms (bin size: 10 deg) between field and IPSPs in PrL (G) and DP (H) show high coherence. I, scatterplot showing a significant relationship between the IPSP amplitude of all mPFC cells (PrL and DP, n = 52) and the area power of the concurrently recorded population field activity; Pearson's product moment correlation (r = 0.45, P < 0.001). Dashed line represents linear regression.
