Fig 1.
MR mid-sagittal image of the corpus callosum of an Atles geoffroyi monkey.
Corpus callosum was divided in five regions according to the anatomic landmarks and Hofer ‘s method [3].
Fig 2.
DTI results of a random subject of this study.
Reconstructed fibers traversing the corpus callosum are over imposed on a mid-sagittal anatomical image. Fibers leaving the CC were divided in five groups (A-E). Rostrum and Genu I (2A), Anterior body II (2B), Medium body III (2C), Posterior body IV (2D), Splenium V (2E). All corpus callosum fibers are incorporated to views 2F (sagittal) and 2G (oblique). Color codes indicate direction. Red: left to right, green: anterior to posterior, blue: superior to inferior.
