Influence of travel time on LFP spectral power. (a) Time-frequency spectrograms did not show a significant change in the theta (3–9 Hz), beta (13–30 Hz), and gamma (30–80 Hz) band power with travel time. Heatmap intensity represents power in decibel. Each tile in the panel represents a 500 ms window at the time of stimulus onset. All the trials in a 1.25 s travel time bin were pooled together to calculate the average spectral power. (b) LFP power spectrum from the example site during a ‘stay’ trial at different travel time bins – low (<3 s, black), medium (3–8 s, blue), and high (>8 s, magenta). Confidence bands represent s.e.m. (c) When late patch residence times were compared with early patch residence times (cyan trace), as opposed to when late patch residence times were compared with medium patch residence times (green trace), the number of sites that showed a difference was not significant.
