Higher frequency of subthreshold oscillations in dorsal versus ventral entorhinal cortex. A. Top: Dorsal view of brain after slicing. Bottom: Sagittal view showing anatomical location of horizontal slices A to H. B. Mean frequency of subthreshold oscillations for neurons from dorsal slices (3.8 – 4.9 mm Bregma) and ventral slices (4.9 – 7.1 mm Bregma) at −50 mV and −45 mV. C. Subthreshold oscillation frequency plotted versus anatomical distance from dorsal surface. D. Examples of subthreshold oscillations at −50 mV in dorsal regions (left) and ventral regions (right). E. Corresponding autocorrelations used to measure frequency in D.
