On the cortical connectivity in the macaque brain: a comparison of diffusion tractography and histological tracing data
2020
NeuroImage
Preserved Fulltext
The diffusion connectivity analysis was performed on a different ex-vivo macaque brain, acquired using multi-shell DW-MRI protocol, at high spatial and angular resolutions. ...
The rich literature in histological connectivity analysis studies in the macaque monkey enables quantitative evaluation of the performance of tractography algorithms. ...
Moreover, the diffusion data were acquired on a brain not used for the histological tracing, and the histological data were collected from several brains, which cannot account for specimen connectivity ...
