Following this, using intraparietal sulcus as a seed to trigger TPN, we found less connectivity in the middle and superior frontal gyrus, visual cortex, parietal lobule, premotor cortex, and primary somatosensory cortex.
** Anterior intraparietal sulcus. Difference corresponds to the correlation between the two seed regions.
"Our results suggest that this is what is achieved in the intraparietal sulcus
, and allows for efficient visual search."
Correlation was computed in specific regions of interest (ROI), involved in the auditory and Wernicke's area (BA22, BA41, and BA42), as well as in brain areas related to multimodal integration, such as the superior temporal sulcus (STS), the middle intraparietal sulcus
(IT), and the insula.
The source of the ipsilesional primary motor cortex activation was further found by the DCM to be the contralesional intraparietal sulcus
They found connections between these duplicate maps and the intraparietal sulcus

Hypotheses 2-4 were investigated using separate region of interest analyses (ROI) for the left angular gyrus (lAG), left and right superior parietal lobules (lSPL and rSPL), and left and right horizontal portions of the intraparietal sulcus
(lHIPS and rHIPS; using the toolbox MarsBar, release 0.44).
During model-based learning, however, the neural signature of a state prediction error appeared in two different areas on the surface of the brain in the cerebral cortex: the intraparietal sulcus
and the lateral prefrontal cortex.
In nonresponders, but not in responders, the lesions extended over large parts of the temporoparietofrontal cortex and the underlying white matter, including the superior parietal lobule, the intraparietal sulcus
, and the posterior part of the temporal lobe.
The study, conducted by researchers Simon Jacob, MD, and Andreas Nieder, PhD, at the University of TE-bingen in Germany, has shown that cells in the intraparietal sulcus
(IPS) and the prefrontal cortex - brain regions important for processing whole numbers - are tuned to respond to particular fractions.
Wan and Schlaug argued that the plasticity in regions of the parietal lobe in which multimodal integration takes place, such as the intraparietal sulcus
, has an effect on related cognitive domains .
