  • Title: Thalamocortical tract between anterior thalamic nuclei and cingulate gyrus in the human brain: diffusion tensor tractography study.
    Author: Jang SH, Yeo SS.
    Journal: Brain Imaging Behav; 2013 Jun; 7(2):236-41. PubMed ID: 23371564.
    Abstract:
    Most portions of the Papez circuit have been identified by diffusion tensor tractography (DTT). However, no DTT study on the proportion of the Papez circuit between the anterior thalamic nuclei and cingulate gyrus has been reported. We attempted to reconstruct the thalamocortical tract between the anterior thalamic nuclei and cingulate gyrus using DTT. All the reconstructed thalamocortical tracts originated from the anterior thalamic nuclei, ascended through the genu of the internal capsule, the anterior limb of the internal capsule, and the white matter around the anterior horn of the lateral ventricle in the anterior and lateral direction, and then terminated at the anterior cingulate gyrus. In terms of FA, MD, and tract volume, no significant differences were observed between hemispheres (p > 0.05). We reconstructed the thalamocortical tract between the anterior thalamic nucleus and cingulate gyrus in the human brain using DTT. We believe that the methodology and results of this study will be helpful to researchers investigating the Papez circuit.
