Frontopontine Fibers
The frontopontine fibersKamali A, Kramer LA, Frye RE, Butler IJ, Hasan KM. Diffusion tensor tractography of the human brain cortico-ponto-cerebellar pathways: a quantitative preliminary study. J Magn Reson Imaging. 2010 Oct;32(4):809-17. doi: 10.1002/jmri.22330. are situated in the medial fifth of the base of the cerebral peduncles; they arise from the cells of the frontal lobe and then pass through the anterior limb of internal capsule at last end in the nuclei of the pons. The frontopontine tract (''tractus frontopontinus'') refers to the combination of the fibers. See also * Paramedian pontine reticular formation The paramedian pontine reticular formation, also known as PPRF or paraabducens nucleus, is part of the pontine reticular formation, a brain region without clearly defined borders in the center of the pons.

Tractography
In neuroscience Neuroscience is the scientific study of the nervous system (the brain, spinal cord, and peripheral nervous system), its functions and disorders. It is a multidisciplinary science that combines physiology, anatomy, molecular biology, development ..., tractography is a 3D modeling technique used to visually represent nerve tracts using data collected by diffusion MRI. It uses special techniques of magnetic resonance imaging (MRI) and computer-based diffusion MRI. The results are presented in two- and three-dimensional images called tractograms. In addition to the long tracts that connect the brain to the rest of the body, there are complicated neural circuits formed by short connections among different Cerebral cortex, cortical and subcortical regions. The existence of these tracts and circuits has been revealed by histochemistry and biology, biological techniques on post-mortem specimens. Nerve tracts are not identifiable by direct exam, computed tomography, CT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
