67 +- This is a three-dimensional representation of the delayed-connectivity structure (space-time) when combined with spatial separation and a finite conduction speed. The connectome consists of the weights matrix giving the strength and topology of the network and the tract lengths matrix gives the distance between pair of regions. When setting a specific conduction speed, the distances will be translated into time delays. The space-time visualizer disaggregate the //weights// matrix and each slice corresponds to connections that fall into a particular distance (or delay) range. The first slice is the complete weights matrix. Click on any of the subsequent slices to see the corresponding 2D matrix plot.
