Global aphasia
Which of the ff lobes are separated by the Cingulate sulcus form the Cingulate gyrus
Frontal and Parietal
Paralysis of left leg
Blockade of right anterior cerebral artery
Stroke in dominant hemisphere
Aphasia
Caused by blockade of MCA
Stroke in nondominant hemisphere
Hemineglect
Blockade of MCA
Contralateral hemianopia with macular sparing
Blockade of PCA (occipital lobe)
Tumor expanding in the BA 44, what will be deficits as it impinges on the adjacent cortical area
