The connectivity between functionally distinct areas in the human brain is
unknown because of the limitations posed by current postmortem anatomical
labeling techniques. Diffusion tensor imaging (DTI) has previously been used to
define large white matter tracts based on well-known anatomical landmarks in the
living human brain. In the present study, we used DTI coupled with functional
magnetic resonance imaging (fMRI) to assess neuronal connections between human
striate and functionally defined extrastriate ventral cortical areas. Functional
areas were identified with conventional fMRI mapping procedures and then used as
seeding points in a DTI analysis to ascertain connectivity patterns between
cortical areas, thus yielding the pattern of connections between human
occipitoventral visual areas in vivo.
