Calculating finely-graded ordinal weights for neural connections from neuroanatomical data from different anatomical studies

Describing the gross organization of the brain at a systems level can be aided by the mathematical analysis of connections between brain regions (Young 1992, Young et al 1995, Scannell et al 1996). These analyses treat each brain region as a ‘black box’ and characterize its contribution to the system’s organization according to its connections with other brain structures. The relative importance of any single connection in terms of the organization of the system may be influenced by the size or ‘strength’ of the connection in question which could be described in terms of the number of neurons that constitute it.
