Magnetic resonance imaging indicated a lesion in the left medial temporal region, including the equilateral thalamus, posterior cingulate gyrus, splenium of corpus callosum, lingual occipital gyrus, and the tail of the hippocampus.
The result suggests that there are impairments in both neurocognitive functions (Clock Drawing Test, Trail Marking Test, Digit Span Test, Auditory Verbal Learning Test, Wisconsin Card Sorting Test, Verbal Fluency Test, Semantic Similarity Test, Stroop Color-Word Test) and social cognitive function (Facial Emotion Cognition Task), and that the cerebral grey matter volume of patients with schizophrenia is also abnormal (left superior frontal gyrus, occipital gyrus, lingual gyrus and upper cerebellum).
For the Success event, SCZ + S patients also had decreased activations in the right medial frontal/anterior cingulate gyrus, cuneus, and cerebellar culmen and left middle occipital gyrus, in comparison to healthy men.
From 1 year before the converters progressed to AD, we observed thinner cortices mainly located in the bilateral occipital and temporal lobes, specifically in the lateral occipital gyrus, entorhinal cortex, temporal pole, and cingulate gyrus (Figure 5).
However, the left cerebellum posterior lobe, left frontal superior orbital lobe (gyrus rectus), right middle occipital gyrus (MOG), and bilateral putamen showed significantly decreased volumes.
(1) This cluster extends medially to include the precuneus and caudally to include the superior occipital gyrus; it includes the most dorsal part of the inferior parietal lobule.
Furthermore, HT7 stimulation as compared with the LI5 stimulation produced a higher BOLD signal response in the bilateral precuneus, precentral gyrus, postcentral gyrus, right middle occipital gyrus, posterior cingulate gyrus, medial frontal gyrus, cingulate gyrus, paracentral lobule, left superior temporal gyrus, and thalamus.
The reduction of GMV in primary visual cortex and the increase of GMV in left lateral middle occipital gyrus in early blindness, when compared to the SC group, may be due to both degeneration and cross-modal functional plasticity.

Compared with the normal controls, the regions expanded in the blind men's brain located at Brodmann 19, 31 where one finds the occipital lobe, cuneus, superior occipital gyrus, limbic lobe, cingulate gyrus.
