case_images: (a) Preoperative T2-magnetic resonance imaging (MRI), axial view showing left hippocampal atrophy and increased diameter of the temporal horn with no evidence of structural lesion. (b and c) Postoperative MRI, T1-coronal, and T2 axial view, showing electrode position in the left hippocampus.

case_images: Fischer, Freiburg, Germany) of a 3387 wide-spaced four contacts deep electrode (DBS Medtronic, Minneapolis, MN, USA) throughout the major axis of the hippocampus using a posterior longitudinal trajectory in February 2006 [Figure 1].
case_images: (a-i) Postoperative magnetic resonance imaging electrode localization and diffuse tensor imaging (DTI) tractrographic reconstruction of Posterior Sylvian Junction (PSJ) (yellow arrow figures a/b/c). (d/e/f) Arcuate-Superior Longitudinal Fascicle (in orange) complex diffusion tensor imaging in axial, coronal, and sagittal view demonstrates the medial position of the electrode in relation to the superficial layer of the PSJ at this level. (g/h/i/j) Inferior Frontal Occipital Fascicle (IFOF) (in green) DTI located in the deep sagittal stratum layer of the PSJ. The electrode is visualized in this layer. (h/j/k) The Tapetum (in red and purple) is identified in the deep layer of the PSJ, medial to the electrode.
