From axons to tracts
From axons to tracts Mohamed 21,098 Views • 3 years ago

The complex circuitry interconnecting different areas in the brain, known collectively as white matter, is composed of millions of axons organized into fascicles and bundles. Upon macroscopic examination of sections of the brain, it is difficult to discern the orientation of the fibers. The same is true for conventional imaging modalities. However, recent advancements in magnetic resonance imaging (MRI) make such task possible in a live subject. By sensitizing an otherwise typical MRI sequence to the diffusion of water molecules it is possible to measure their diffusion coefficient in a given direction1. Normally, the axonal membrane and myelin sheaths pose barriers to the movement of water molecules and, thus, they diffuse preferentially along the axon2. Therefore, the direction of white matter bundles can be elucidated by determining the principal diffusivity of water. The three-dimensional representation of the diffusion coefficient can be given by a tensor and its mathematical decomposition provides the direction of the tracts3; this MRI technique is known as diffusion tensor imaging (DTI). By connecting the information acquired with DTI, three-dimensional depictions of white matter fascicles are obtained4. The virtual dissection of white matter bundles is rapidly becoming a valuable tool in clinical research.

Our journey begins with a transverse section of tightly packed axons as seen through light microscopy. Although represented as a two-dimensional "slice", we see that these axons in fact resemble tubes. A simulation of water molecules diffusing randomly inside the axons demonstrates how the membranes and myelin hinder their movement across them and shows the preferred diffusion direction --along the axons. The tracts depicted through DTI slowly blend in and we ride along with them. As we zoom out even more, we realize that it is a portion of the corpus callosum connecting the two sides of the brain we were traveling on and the great difference in relative scale of the individual axons becomes evident. The surface of the brain is then shown, as well as the rest of the white matter bundles--a big, apparently chaotic tangle of wires. Finally, the skin covers the brain.

With the exception of the simulated water molecules, all the data presented in the animation is obtained through microscopy and MRI. Computer algorithms for the extraction of the cerebral structures and a custom-built graphics engine make our journey through the brain's anatomy possible in a living person.

Diverticulosis of the Colon
Diverticulosis of the Colon Mohamed 25,477 Views • 3 years ago

The colonoscope is slowly withdrawn during this screening colonoscopy down from the transverse colon, back around the splenic flexure, and down the descending colon, and reveals this finding a colonic diverticula. Diverticulosis is a common, acquired, age-related occurrence affecting over 50% of the... western adult population over the age of 50. It is seen rarely in Africa and Asia where the dietary fiber content is traditionally higher. Thus most investigators feel that low fiber diets are related to the development of this condition. Ironically, colonic diverticula are not true diverticula but rather pseudodiverticula in that the sac includes layers of the mucosa and submucosa that push through rather than include the outer muscular layer. As with the small bowel the colon has an inner circular muscular layer, but the outer longitudinal layer is composed of three bands of muscle that run the length of the colon known as teniae. Diverticula occur in rows between the mesenteric and two antimesenteric teniae where the colonic wall is further weakened by the defect caused by the perforating vasa recti artery which supplies the colonic mucosa. Occasionally, the anatomic propensity of diverticula to form in rows is quite apparent as seen when this clip is replayed in slow motion. Most often, however, the arrangement of the diverticula appears random due to the angulation of the bowel and thickening of the semi lunar folds. The conditions that cause these pulsion diverticula are not know with certainty but may include high intrahaustral pressures, muscular hypertrophy, and age related alterations in collagen cross linking. Diverticula can bleed or can abscess and perforate. The incidence of diverticulitis or diverticular bleeding is in the range of 1:1,000 patients with diverticulosis.
