Linking Cellular Mechanisms to Behavior: Entorhinal Persistent Spiking and Membrane Potential Oscillations May Underlie Path Integration, Grid Cell Firing, and Episodic Memory
Figure 5
Phase relative to location in the
environment. (a) Spiking phase due to
precession (with refractory period).
Note that phase depends upon location, but is circularly symmetric. (b) Dendritic phase of oscillations contains
more complete continuous representation of location. (c) Plot of the angle of a single distal
visual stimulus as a rat moves around in an environment, indicating similarity
of allocentric stimulus angle to integrated dendritic phase in a grid cell.
