Longitudinal fissure result from lesions to them. Diffusion tensor imaging (DTI or dMRI) along with fiber-tracking (FT) algorithms and functional Magnetic Resonance Imaging (fMRI) is used to image these bundles. For instance, occipital-callosal fiber tracts were localized with 1–2 mm precision using DTI-TF techniques - which are very important for the cooperation of visual cortices, and any lesion to them can lead to alexia, the inability to read. Longitudinal fissure The longitudinal fissure (or cerebral fissure, median longitudinal fissure, or interhemispheric fissure) is the deep groove that separates the two hemispheres of the vertebrate brain. The medial surfaces of the two hemispheres
Conard Fissure Conard Fissure The Conard Fissure is a geologic feature in Northern Arkansas where a deposit of Pleistocene fossils was discovered in 1903. Several specimens from saber-toothed cats were found there among other species. The fissure is located near the Buffalo National River in Boone County, Arkansas, approximately 15 miles south of the town of Harrison. It lies approximately one mile north of the river near the border of Newton and Boone County. The fissure is named after Waldo Conard who owned the land that the fissure is situated on. The original excavation of the Conard Fissure was performed by Barnum
