Fig 4.

DM has higher theta power and frequency than delay and running periods in speed-matched conditions. A: Power spectra in speed-matched trials during DELAY (green) and DM (red) for each animal (mean ± SEM over trials). For speed distributions, see Supporting Information Figure S1. B: (Left) Normalized theta power in DM and DELAY (mean ± SEM, n = 5). (Right) Theta peak frequency for the power spectra in A. C,D: The same as above but for DM and RUN periods (*P < 0.05, Student's t-test). [Color figure can be viewed in the online issue, which is available at wileyonlinelibrary.com.]
