Exploration of the brain from its superior aspect
Inferior occipitofrontal fasciculus and external sagittal stratum
The superior longitudinal fasciculus has been further cut away to expose the inferior occipitofrontal fasciculus completely. Fibers of this latter bundle merge with fibers of the geniculocalcarine tract (and probably other pathways) to form the external sagittal stratum, a well-defined band which extends toward the occipital pole.
