The angular gyrus is a converging region of the inferior posterior parietal lobe interconnecting the temporal, parietal and occipital cortices and is seen as an integrative hub for multiple psychological processes (Seghier, 2013).
Doidge's explanation is that "competitive plasticity" occurred in the brain, disabling the posterior parietal lobe from processing the pain signals as it had in the past.
On examination, the patient is a well-developed, active female with a 2-cm, bluish nodule with an overlying atrophic, glistening membrane on the posterior parietal scalp, lateral to the midline.
In some cases, it branches from the rolandic artery or from the posterior parietal artery.
Posterior reversible encephalopathy syndrome (PRES) or reversible posterior leukoencephalopathy syndrome was first described by Hinchey, in 1996, as a reversible syndrome manifested with an acute headache, consciousness impairment, seizures, and visual deficits, associated with white matter changes predominately affecting the posterior parietal and occipital lobes of the brain but also involving the brainstem, cerebellum, and other cerebral areas [1-3].
A CT scan of the brain showed bilateral occipital infarcts and a right posterior parietal lobe infarct (Figure-2).
Non-contrast computed tomography of the brain revealed the presence of white matter edema at the occipital and posterior parietal areas (Figure 1), which was suggestive of PRES.
Patients exhibited stronger signal decreases which were relative to controls in anterior cingulate, middle and superior temporal, superior frontal, and posterior parietal regions.
On the detailed brain scans, the researchers found that the women with depression or bipolar disorder had different levels of activity than healthy women in the brain's right posterior parietal cortex.
It was clear that certain neurons in the posterior parietal cortex are responsible for the planning of arm movements.
Thus the level of conscious perception seems to require activation of the secondary somatosensory cortex (SII) reflected by P100 [17 18] followed by activation of posterior parietal cortices reflected by N140 [19-21].
