We report the case of a 72-year-old right-handed man, M. B., who, after a right posterior parietal infarction, developed a spatial or afferent agraphia. Language function and limb praxis were normal. The patient had no left-sided neglect... B Croisile,O Hibert - 《Aphasiology》 被引...
Both post-stroke mania and psychotic symptoms have been consistently associated with right hemisphere damage, but, to our knowledge, were not previously reported after the same injury. We believe our patient provides evidence that the same anatomic dysfunction, in this case a temporoparietal infarct...
A data-driven pattern discovery framework enabled the derivation of coherent patterns of stroke lesion topographies directly from the segmented high-resolution brain scans from 555 stroke patients. This unsupervised, multi-to-multi mapping approach led to unique, predominantly right-hemispheric (a) or l...
Figure 4.. Abdomen magnetic resonance imaging revealing an acute deep vein thromboses in the right common iliac, external iliac, and internal iliac veins (white arrow).Figure 5.. T2 flare brain magnetic resonance imaging revealing a lacunar infarct in the left cerebellar hemisphere (white arrow)....
Fig. 1. CTP (from left to right MTT, CBF, and CBV maps) and EEG tracings (below). (A) Acute epileptic aphasia with ASPECT 10 on NECT, negative CTA and focal increase of perfusion assessed on CTP maps congruent with epileptic foci characterized by left fronto-parietal sharp waves; (B)...
2005) and right-lateralised ventro-lateral prefrontal cortex (Jacobson, Blanchard, Connolly, Cannon, & Garavan, 2011). Further, less consistent non-frontal contributions to the set-switching component of the TMT were also observed across these studies, including insular, parietal and temporal activati...
Alterations cerebral peduncle (arrows) and parietal cortex (arrowheads). MRI, magnetic reso- nance imaging; MTR, magnetization transfer ratio. corticospinal tract (Figure 1g–i). At 1 wk postinsult, intensity levels in MR scans were similar, and differences between left and right hemispheres ...
In case 2, DWI obtained 7 days after the onset of a right internal capsule lacunar infarct showed high signal from the right corticospinal tract in the brainstem, which was less marked 15 days after onset. In case 3, MRI on postnatal day 7 showed a cerebral haemorrhage in the right ...
Two microliters (2 μL) of virus (titer, 1 × 1010 TU/mL) was injected into right cortex. After injection, the needle remained in place for 5 min and was then slowly retracted to avoid leakage. The mice were placed on a heating pad throughout the duration of the surgery. After ...
A and B: Axial NCHCT images obtained at admission showing subtle obscuration of the right lentiform nucleus (open arrow, A) and loss of gray-white differentiation in the right frontal lobe (white arrow, A and B), consistent with right MCA territory infarct. C and D: Axial NCHCT images ...
