Connectivity Matrix

This is a connectivity
matrix N (inputs to each area) x N (areas that send inputs) compiled by examining the
primary literature of anatomical tract-tracing studies in the frontal, parietal
and temporal cortex of the macaque brain. Inputs
come from studies using injections of retrograde and anterograde transport of
tracers. In many cases both were used in the same study to characterize the
connectivity. The strength of inputs to each area from any other
area is based on the data reported in the examined studies and, to a lesser
extent, by a quantitative inspection of the data. Accordingly, we classified
inputs to each area as absent (0), weak (16), moderate (33), medium (50),
strong (67), or very strong (100).
