Figure 4. Synaptic correlations of ANOs.

A and B, spontaneous excitatory AMPA receptor-mediated postsynaptic currents (EPSCs) and inhibitory GABA_A receptor-mediated IPSCs recorded in CA3 pyramidal cell (upper traces) are phase locked to field ANOs (lower traces). EPSCs were recorded at the reversal potential of the GABA_A (V_h =−65 mV) and glutamate receptor-mediated currents (V_h = 0 mV). Bottom, cross-correlation between the current passing through the cell membrane and the extracellular field potential during ANOs. C, synaptic events and the extracellular field potential during a single cycle of ANOs. Below, occurrence of MUA relative to the extracellular field potential for 80 cycles of ANOs. Time zero was set to the negative phase of the extracellular field oscillations.
