They found decreased global efficiency and decreased nodal efficiency in the left supplementary motor cortex, contiguous precentral regions, the calcarine cortices, secondary visual regions, and the certain regions within the cerebellum in PD patients.
The distinction between a bilateral infarct in the posterior cerebral artery territory and PRES can be made based on the fact that PRES does not commonly affect the calcarine and occipital lobe structure.
Studies also show that the periosteal blood flow plays an important role in the area of the calcarine spur and that the size of the fracture fragment and the extent of the dislocation permits conclusions to be drawn about the risk of necrosis developing in and around the humeral head.
Compared with the resting-state, acupuncture at the real acupoints activated brain regions primarily in the left calcarine gyrus, bilateral middle occipital gyrus (BA19), bilateral middle temporal gyrus (left BA 22), left inferior temporal gyrus, left inferior frontal gyrus, left superior medial prefrontal gyrus (left BA 10), right anterior cingulate cortex (right BA 10), left postcentral gyrus, left caudate nucleus, and the bilateral cerebellum (Crus 2 and VIII).
The posterior cerebral artery (PCA) is divided into four segments: P1 (precommunicating segment), P2 (postcommunicating segment), P3 (quadrigeminal segment), and P4 (calcarine segment).

A brain imaging study found that the areas of the brain most vulnerable to the toxic effects of mercury are the calcarine region, pre- and postcentral gyri, and the temporal transverse gyrus (Taber & Hurley, 2008).
Dissection of the fixed brain should always be standardized and basic sampling for dementia evaluation should include blocks from the frontal, parietal, and temporal cortex; occipital cortex around the calcarine fissure; the hippocampus at the level of lateral geniculate body; the striatum; the mesencephalon at the level of the oculomotor nerve; the pons at the level of the locus coeruleus; the medulla oblongata at the level of the inferior olives; and the cerebellum and dentate nucleus.
Transient activity in human calcarine cortex during visual imagery.
Lamy C et al in 2004 described highly characteristic neuro-imaging features include abnormal increased T2W/FLAIR signal, thought to be vasogenic oedema, primarily within the white matter of the posterior circulation territories with typical sparing of the calcarine and paramedian regions of the occipital lobes.6 The frontal/temporal white matter may be involved as well as gray matter structures such as the cortex and basal ganglia.
