properties of interareal connections of the marmoset cerebral cortex, using data from retrograde tracer injections.We found
that the connectivity weights are highly heterogeneous, spanning 5 orders of magnitude, and are log-normally distributed.
The cortico-cortical network is dense, heterogeneous and has high specificity. The reciprocal connections are the most
prominent and the probability of connection between 2 areas decays with their functional dissimilarity. The laminar
dependence of connections defines a hierarchical network correlated with microstructural properties of each area. The
marmoset connectome reveals parallel streams associated with different sensory systems. Finally, the connectome is
spatially embedded with a characteristic length that obeys a power law as a function of brain volume across rodent and
primate species. These findings provide a connectomic basis for investigations of multiple interacting areas in a complex
large-scale cortical system underlying cognitive processes.
