Extended Data Figure 9: Activity of CA1 neurons in the passive playback + reward experiment.
From: Mapping of a non-spatial dimension by the hippocampal–entorhinal circuit
a, Four examples of neurons in the PPR task, plotted as in Fig. 3. Firing fields spanned the entire behavioural task, but were wider than in the SMT, except possibly near the reward (for example, cell 4). b, Activity of all 44 cells whose firing rates were significantly modulated in the PPR task, plotted as in Fig. 2. Of the 21 cells that had firing fields during sound presentation, the fields of 14 were better aligned to sound frequency than to other task parameters.
