Changes in firing rate for mPFC cells significantly and nonsignificantly phase locked to local low gamma oscillations

	CNO*	CNO ns	Veh*	Veh ns	Total

Increase FR	8	7	8	32	55
No change	0	1	1	0	2
Total	25	29	20	47	111

All medial prefrontal cortex (mPFC) cells were categorized as increasing firing rate (FR), decreasing firing rate, or no change in firing rate between the premaze rest and the postmaze rest (within session comparison). These cells were also categorized as to whether they were significantly phase locked to local gamma oscillations. CNO, clozapine N-oxide; Veh, vehicle.

^*Significantly phased locked; ns, not significantly phased locked.
