Figure 5.

Basic place cell characteristics were similar on the chamber and cylinder floors. A–C, Overall firing rate (A), spatial information content (B), and local smoothness (coherence) (C) of place cell firing in the cylinder and chamber. Probabilities are given for significant differences relative to the cylinder condition. The significant differences arise because discharge on the narrow stairs in the chamber was different from discharge on the cylinder or chamber floors. Error bars indicate SEM.
