Figure 5. Firing properties at rest in the presence of synaptic blockers.

A, distribution of resting membrane potentials in Re cells recorded in the combined presence of blockers of AMPA/kainate, NMDA and GABA_A receptors. B, relative proportions of spontaneously firing and silent cells under these conditions C, distribution of mean instantaneous AP frequency at resting membrane potential during a 60 s epoch recorded in whole cell configuration. All recordings were made in the presence of NBQX (5 μm), gabazine (5 μm) and L‐689560 (5 μm).
