Extended Data Fig. 2. Stability of the imaging field of view.
a. Example session mean image, image from the engaged trials, and image from the disengaged trials, and local correlation map between them. For each pixel x in the FOV, the local neighborhood used for correlation calculation is a square of 41 by 41 pixels with x in the center. Similar results were obtained from 32 sessions that met inclusion criteria and contained more than 10 engaged and disengaged trials. b. Correlation between the mean session FOV image and FOV images of the engaged and disengaged trials. Two-sided Wilcoxon signed rank test, p = 0.06. The mean correlation between FOVs in the engaged and disengaged trials is 0.992. n = 32 sessions, 8 mice. c. Mean noise in the engaged and disengaged trials. Noise was defined as the activity less than 2 standard deviations from the mean activity of each cell. Two-sided Wilcoxon signed rank test, p = 0.46. n = 32 sessions, 8 mice. d. Standard deviation of noise in the engaged and disengaged trials. Two-sided Wilcoxon signed rank test, p = 0.97. n = 32 sessions, 8 mice.
