Corticoreticular pathway in the human brain: Diffusion tensor tractography study

Functional Role of the Corticoreticular Pathway in Chronic Stroke Patients

“…The CRP descends through the corona radiata and posterior limb of the internal capsule just anterior to the CST; patients with complete injury of the CST are vulnerable to severe injuries in the CRP pathway. 24 Second, further prospective studies involving follow-up clinical and DTT data from acute to chronic stage of stroke are warranted because this study was performed retrospectively. Third, DTI analysis is operator-dependent, and because of fiber complexity and crossing fiber effect, it may underestimate the fiber tracts.…”

“…For analysis of the CRP, the seed region of interest (ROI) was placed on the reticular formation of the medulla and the target ROI on the midbrain tegmentum ( Figure 1C). 24 For analysis of the CST, the seed ROI was placed on the CST portion of the pontomedullary junction and the target ROI on the CST portion of the anterior midpons. 30 The CRP and CST were determined by selection of fibers passing through seed and target ROI.…”

“…23 A study using DTI reported on a method for identification of the CRP in the live human brain. 24 Few studies have reported on injury of the CRP in patients with stroke and traumatic brain injury. 25,26 However, little is known about the relation between the CRP and walking ability.…”

Prognosis and Recovery of Motor Function with Lesion–Symptom Mapping in Patients with Stroke

“…Brain & NeuroRehabilitation it passes through the tegmentum and terminates at the PMRF [46]. Freund et al [47][48][49] reported an association between PMC lesions and proximal muscle weakness (shoulder and hip muscles).…”

Quantification of white matter fibre pathways disruption in frontal transcortical approach to the lateral ventricle or the interventricular foramen in diffusion tensor tractography

“…[9,12]. Furthermore, DTT does not reflect small neural pathways and is restricted to regions of non-crossing bundles [54]. It seems highly probable that the use of more precise analytic algorithms, including cross fibres and small neural bundles, would alter the results of that study.…”
