Figure 1From: Prefrontal-hippocampal theta coherence, sharp wave ripples, and bursts of cortical unit activity underlie choices and encoding in the radial arm mazeAverage hippocampal and prefrontal theta and SWR power centered on reward acquisition. During test choices (B, D), PFC (D) activity resembles that in HC (B). On the other hand, during training (A, C), HC (A) shows the pattern of activity associated with reward sites, and PFC (C) does not. Shaded regions, 95% confidence intervalsBack to article page
