WebApr 13, 2010 · The anatomic course of the optic radiation, especially Meyer's loop, exhibits considerable intersubject variability (Ebeling and Reulen, 1988; Sherbondy et al., 2008). Hence, it is essential to determine its exact anatomy in individual subjects in order to minimize damage to the visual fiber system during neurosurgery. In fact, the risk of ... WebFeb 1, 2014 · For example, the extent of the optic radiation (OR) of the Meyer loop is frequently underestimated. 6 Probabilistic tractography assesses the probability that a voxel is connected to a given start point, by means of iterative random walks. 7 This method exploits the statistical nature of the information obtained by DWI and determines the most …
WebSep 20, 2013 · VFDs are a consequence of damage to the most anterior portion of the optic radiation, Meyer's loop. Anatomic dissection reveals that the anterior extent of Meyer's loop is highly variable and may clothe the temporal horn, a key landmark entered during temporal lobe epilepsy surgery. Experience from surgery since the 1940s has shown that VFDs ...
