Effect of 2 μm CNQX on oscillations recorded from individual neurons

A, representative trace pairs of intracellular (layer V; upper trace) and extracellular (layer III; lower trace) recordings corresponding to spontaneous discharges produced during application of BMI, BMI+CGP35348 and BMI+CGP35348+CNQX (2 μm). Note the abolishment of the oscillation both at the intracellular and extracellular levels with CNQX. B, effect of an intracellular current pulse applied to the cell shown in A during the three pharmacological conditions. Note that there were no significant changes in the intrinsic repetitive pattern of discharge.
