Stability of place-field location. A, Distribution of centroid shifts in the place fields between adjacent recording sessions (1–2, 2–3, 3–4, 4–7, 7–8, 8–9, and 9–10). B, Left, Centroid shifts of the place fields between adjacent recording sessions. Right, Centroid shifts between sessions with a 3 d interval. C, Right, PV correlation of place cells between adjacent sessions. Left, PV correlation of place cells between sessions with a 3 d interval. D, The place-field location of all cells at the Nth session and N + 1th session (n = 3296 cells). Gray bars indicate the reward position. Data are shown as mean ± SEM.
