"Place and grid cells in a loop: implications for memory function and spatial coding"

Based on the anatomy of the entorhinal-hippocampal circuitry, we constructed a model of place and grid cells organized in a loop to investigate their mutual influence in the establishment of their codes for space.

This analysis relies mostly on connectedness, a structural feature of speech that is anti-correlated with negative symptoms."

Asymmetry of the temporal code for space by hippocampal place cells"

Here we show that the spike timing of place cells couples to theta phase before major increases in firing rate, anticipating the animal’s entrance into the classical, rate-based place field. "

Electrophysiological evidence that the retrosplenial cortex displays a strong and specific activation phased with hippocampal theta during paradoxical (REM) sleep"

It is widely accepted that cortical neurons are similarly more activated during waking and paradoxical sleep (PS, aka REM) than during slow wave sleep (SWS). "
