Movie S2.

This media file shows the network maps for the entire data duration of ∼22 min (1,333 s) overlaid on the slice (four snapshots shown in Fig. 5D). Neurons are shown with red circles and the selected 20 neurons are highlighted in yellow, scattered across the whole slice. The white directed arrows represent the detected G-causal links, where the width of each arrow at each time reflects its significance level (i.e., its corresponding J-statistics). The horizontal cursor at the bottom represents time in seconds.
