Figure 8.

Comparison of the rhythmic properties between anteroventral theta cells classes. A, Intertrain intervals distribution (mean ± SEM) for directional theta (top), slow-spiking theta (middle), and fast-spiking theta (bottom) cells. Note that the peaks and troughs for all cell classes share the same rhythmic pattern, with the highest peak located at 125 ms (8 Hz). B, C, Relative number of spike trains (B) and theta index values (C) for directional theta unit, fast-spiking theta, and slow-spiking theta cells. Error bars indicate SEM.
