6] Typical patterns of brain involvement in NMOSD, although not pathognomonic, include lesions of the dorsal medulla/area postrema, periependymal regions in the brainstem, diencephalic structures, or cerebral hemispheres or long lesions spanning much of the corpus callosum or corticospinal tracts, corresponding to regions of high AQP4 expression.
Indeed, there is now good evidence that other areas, besides the hippocampus, are also important for declarative memory, such as the diencephalic midline (Squire & Wixted, 2011) and, in particular, the prefrontal cortex (Simons & Spiers, 2003).
Spasmus nutans may be associated with arachnoid cyst, optic nerve hypoplasia, diencephalic syndrome, subacute necrotizing encephalopathy (Leigh disease) and intracranial tumors.
As a midline structure between the corpus callosum and the fornix, it allows for communication between higher order diencephalic structures and the limbic system.
Similarities in the gross anatomy of the pig brain to that of the human brain are shown in the hippocampus, subcortical and diencephalic nuclei, and brainstem structures (Lind et al.
Magnetic resonance imaging of the hippocampal formation and mammillary nuclei distinguish medial temporal lobe and diencephalic amnesia.
A decrease in the number of GFP-labeled neurons was observed in the telencephalic (TC) and diencephalic (DC) clusters (Figure 1a,b,c,d) in embryos treated with ziram.
Regions of interest were evaluated on standardized axial mesencephalic and diencephalic planes.
The tenn "paroxysmal sympathetic hyperactivity" or PSH has been adapted and replaced previous terms used to describe the syndrome, such as episodic autonomic instability, dysautonomia, autonomic dysregulation, central autonomic dysfunction, paroxysmal autonomic instability with dystonia, sympathetic storming, autonomic storming, dysautonomic crises, and diencephalic fits (Baguley et al.
The stage of diencephalic herniation may be mimicked by drugs, toxins, metabolic abnormalities as well as intra- and post-ictal states.
In most cadaveric dissection, Liliequist's membrane was composed of two distinct leaves: A diencephalic leaf directed toward the diencephalon (separated chiasmatic and interpeduncular cisterns) and a mesencephalic leaf directed toward the mesencephalon (separated interpeduncular and prepontine cisterns).
