Localized semi-nonnegative matrix factorization (LocaNMF) of widefield calcium imaging data
Fig 8
Correlation maps of temporal components extracted by LocaNMF show consistencies across sessions and animals.
A. Top canonical correlation coefficient between the temporal components of any two regions, shown for four different sessions of 49 to 64 minutes each, recorded across two mice. B. Example traces of two highly correlated regions. C. Violin plot of mean squared difference between the correlation maps of the 20 different sessions across 10 mice; on average, within-mice differences are smaller than across-mice differences (One-tailed t-test p = 0.0025).
