Example for temporal ICA. Performing ICA on the principal component timeseries matrix TPCA. a) above: spatial component that contains a glomerulus pair (black pixels); below: image from raw movie, indicating the shapes of the left and right ALs. b) Timeseries component (that corresponds to ) on a 200-timepoints interval including a double odor presentation (marked by the bars). c) For comparison, we show the mean timeseries for the glomerulus pair on the raw movie A.
