These maps known as connectomes (see pictures on the left) are not showing the individual neurons. The connectome fibres are like the information superhighways of the brain.
Another description would be wiring diagram. Connectomes do not reveal all the details about the brain’s network, but they show the network structure at a higher level.
The ultimate goal is to have the complete mapping of all neural connections in the living brain.
The production and study of connectomes is known as connectomics which tries to understand the organization of neural interactions within the brain.
For this project the Laboratory of Neuro Imaging (LONI) at UCLA has partnered with the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH). Study participants are scanned at MGH.
There is also the dHCP (Developing Human Connectome Project) led by King’s College London, Imperial College London and Oxford University. Their goal is to create a dynamic map of human brain connectivity from 20 to 44 weeks post-conceptional age and link together with behavioral and genetic information. They are hoping that this study will lead to a better understanding of Autistic Spectrum Disorder or Cerebral Palsy.
