Fiber Pathways Of The Cerebrum 3d Anaglyph Youtube A video lecture about the projection, association and commissural pathways of the cerebrum. dissections by kaan yagmurlu while working in the laboratory of d. Introduction. performing safe and successful surgery on cerebrum lesions requires a good understanding of the 3 dimensional (3d) topographic anatomy of the cerebral fiber tracts in the human brain and their interrelationships. white matter tracts have long been an essential component of neuroanatomy and neurosurgery education.
White Matter Of Cerebrum Anatomy 3d Association Fibers Anatomy Abstract. background: the fiber tracts of the cerebrum may be a more important determinant of resection limits than the cortex. better knowledge of the 3 dimensional (3 d) anatomic organization of the fiber pathways is important in planning safe and accurate surgery for lesions within the cerebrum. objective: to examine the topographic anatomy. Fiber dissection is one method that delineates the complex structures of the cerebrum, cerebellum, and brainstem. 8,25,26 this method was developed by klingler and his colleagues. 10 the procedure, which involves removing white matter tracts to reveal the brain's anatomic organization, was the first to provide surgeons a full view of the 3d. Thus, these paths formed a single biaxial system. this pattern was typical of cerebral white matter. the 3d structure of cerebral pathways was demonstrated through analysis of several path neighborhoods in a single region. deep white matter of the occipital lobe—the sagittal stratum—of the rhesus monkey is shown in fig. 2. here, four seed. Commissural pathways are white matter fiber bundles that bridge the midline and connect identical cortical structures in the opposite hemispheres of the brain in contrast to commisural fibers, there are association fibers, that connect different cortical regions within the same hemisphere, and projection fibers, that connect a cortecal region to lower parts of the brain or the spinal cord.

The cerebral fiber pathways formed a rectilinear three dimensional grid continuous with the three principal axes of development. cortico cortical pathways formed parallel sheets of interwoven paths in the longitudinal and medio lateral axes, in which major pathways were local condensations. cross species homology was strong and showed emergence. Fiber dissection is a technique that allows isolation of whole fiber pathways, revealing 3d structural and functional relationships of white matter in the human brain.
