Hees et at (2014) Superior frontal gyrus, angular gyrus and superior left temporal gyrus activated without intervention.
More specifically, considering the activation maps for spontaneously named items to be trained or untrained, the recruitment includes the left primary motor area, left angular gyrus, and right fusiform gyrus.
Significantly negative correlations were found between YBOCS scores and left superior parietal lobe gray matter r(28)= -.68, p<.001, right angular gyrus white matter r(28)= -.60, p<.001, and right superior temporal gyrus white matter volumes r(28)= -.61, p<.001.
Hamilton and team, which also included Jonathan Peelle PhD, an assistant professor in the Department of Otolaryngology at the Washington University School of Medicine, Michael Bonner, PhD, a postdoctoral fellow in the Department of Psychology at Penn, and Murray Grossman, MD, EdD, professor of Neurology and director of the Penn Frontotemporal Dementia Center, looked at the role of the left angular gyrus in semantic memory by applying high definition tDCS in healthy adults to modulate neural activity and determine its effect on semantic integration.
Particularly in cases of associated numbness to the contralateral hemibody [20], a perisylvian propagation can be hypothesized trough the AF/SLF complex, which connects the extrastriate (V4-V5) lateral cortices through the parietal region (angular gyrus (AG)) and then to premotor and motor cortical areas.

Consistent with this, studies confirm that the critical region mediating hemispatial neglect is the territory of the middle cerebral artery; specifically the angular gyrus on the lateral surface of the inferior parietal lobule (IPL).
They are also measuring changes in brain regions such as the angular gyrus, an area that has been associated with out-of-body experiences.
For instance, in the chapter on OBEs, she proposes a role for the angular gyrus and the temporal lobe in accessing psychic information via an OBE.
Wolf joins this research to other, neurological work on the structure of the reading brain and the absolute necessity for the myelination of brain neurons in the angular gyrus region before a child can really learn to read.
However, only adults exhibited strong responses in another left-brain structure, the angular gyrus. This tissue may foster experienced readers' ability to ladle out a stream of words from a stew of spelling regularities and exceptions, Booth proposes.
