Small and local artefacts correction and neuropil decontamination. a Fluorescence activity of the same ROIs of Fig. 2a after the correction of artefacts obtained through the reassignment of those pixels that maximize the SNR (top) or through the correction strategy that uses the displacements estimated using the NoRMCorre algorithm [44] on the reference box with a smoothing window of 10 s (bottom). b Effects of different artefacts corrections strategies on the SNR and pairwise correlation of fluorescence traces for different surrounds and animal states. Extended values in Table 4. c Correlations between the displacement along the x-axis (left) or y-axis (right) estimated using different strategies in anesthetized (top) and awake (bottom) animals. d Effects of neuropil decontamination strategies on the SNR and pairwise correlation of fluorescence traces for different surrounds and animal states. Extended values in Table 5
