Fig. 3.
Relationship of subthreshold membrane potential oscillations to sag potential. For single neurons in dorsal (A) and ventral entorhinal cortex (B), traces on left show membrane potential responses to multiple current injection levels. Single traces (right) show sag potentials at higher resolution. C. First time constant of sag potential (ms) plotted versus anatomical location. D. Time constant of sag potential plotted versus subthreshold oscillation frequency.
