Figure 5.

Spatial, anatomical, and phase-related properties of interneurons. Top, Average interneuron firing rate activity classified by EEG state and anatomical location on the dorsoventral axis. Interneurons exhibiting phase precession fired at significantly higher rates during theta and ripple epochs (*p < 0.05; ***p < 0.01). Middle, The number of precessing and non-precessing interneurons observed in both the dorsal and middle hippocampus. Bottom, Mean pyramidal place field size versus mean interneuron field size for each brain region and track size for all rats. The diagonal line indicates identity.
