Example for temporal ICA. Performing ICA on the principal component timeseries matrix T^PCA. a) above: spatial component $S_{1J}^{ICA}$ that contains a glomerulus pair (black pixels); below: image from raw movie, indicating the shapes of the left and right ALs. b) Timeseries component $T_{I1}^{ICA}$ (that corresponds to $S_{1J}^{ICA}$) 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.
