Document Summary

Dti detects the directional movement of water molecules to image nerve fiber pathways in the brain. Connectome- a comprehensive map of neural connections in the brain. The human connectome project aims to build a network model of the human brain in healthy subjects. Build a network map of major connections in the normal brain". You can take this map and compare the normal network to those in people suffering from a number of disease states. When discussing this project, it only references the major pathways in the brain, not every single connection. The c. elegans connectome consists of 302 neurons and it took 12 years to fully map. The human neocortex has approximately 10 billion neurons and around 100 trillion connections. Given the current rate of mapping, it will take about 397 million years to establish all the connections in the human brain. Mri provides a static image of the brain.
