referenceBrain areas implicated in prosociality, empathic concern, and experience sharing include the anterior cingulate cortex (ACC), inferior frontal gyrus (IFG), posterior superior temporal sulcus (pSTS), and inferior parietal lobule (IPL), as cited by Singer and Lamm (2009), Frith and Frith (2012), Fan et al. (2011), and Roy et al. (2012).

claimThe right inferior parietal lobule (IPL) is associated with Theory of Mind (ToM), whereas the left inferior parietal lobule (IPL) is involved in representing one's own mental states.

claimImagined self-action relative to imagined experimenter action strongly activates the inferior parietal lobule (IPL), including the temporoparietal junction (TPJ), the somatosensory cortex, and the precuneus.

measurementTaylor et al. (2012) found that adept Zen meditators exhibit stronger connectivity between the dorsomedial prefrontal cortex (DMPFC) and the inferior parietal lobule (IPL) compared to novices.

measurementMeditators show increased BOLD activity in the right anterior insular cortex (AIC), somatosensory cortex (SII), and the inferior parietal lobule (IPL) when using an experiential focus compared to control subjects, according to Farb et al. (2007).

quoteBarrett and Griffiths (2017) stated: “Decreased activity in the IPL (and specifically in the angular gyrus), and decreased communication between the IPL and other areas involved in maintaining a sense of self (such as the PCC) are observed both in studies of meditation and in studies of classic hallucinogens.”

claimSpeech production is compromised under LSD because of the lack of connections with the neocortical components involving the frontal lobe (Broca's area), while the language capacity for understanding meaning persists because of its lower anatomical basis near the Default Mode Network (DMN) component, the inferior parietal lobule in the superior temporal gyrus (Wernicke's area).

quoteJouena et al. (2015) describe the distributed cortico-striatal network involved in understanding sentences and pictures as: “included the middle and inferior frontal gyri, the parahippocampal-retrosplenial complex, the anterior and middle temporal gyri, the inferior parietal lobe in particular the temporo-parietal cortex [with]…a multi-component network reaching into the temporal pole, the ventral frontal pole and premotor cortex.”

A Synergistic Workspace for Human Consciousness Revealed by ... elifesciences.org eLife 2 facts

claimRegions showing consistent decreases in ΦR during loss of consciousness were primarily members of the global synergistic workspace, specifically the default mode network (bilateral precuneus and medial prefrontal cortex) and bilateral inferior parietal cortex, with involvement of left temporal cortices.

claimThe default mode network (DMN) comprises the posterior cingulate, precuneus, medial prefrontal cortex, and inferior parietal cortices.

Battle of the Brain: Men Vs. Women [Infographic] nm.org Northwestern Medicine 1 fact

claimThe inferior-parietal lobule tends to be larger in men and is linked to mathematical problems, estimating time, and judging speed.

Global workspace theory - Wikipedia en.wikipedia.org Wikipedia 1 fact

claimBrain regions including the prefrontal cortex, anterior temporal lobe, inferior parietal lobe, and the precuneus integrate information over space and time by sending and receiving projections to and from a broad variety of distant brain regions.

4.5 Consciousness – Cognitive Psychology nmoer.pressbooks.pub Pressbooks 1 fact

referenceThe Global Neuronal Workspace Theory of Consciousness, proposed by Dehaene and Changeux in 2011, postulates that the sharing of information among the prefrontal, inferior parietal, and occipital regions of the cerebral cortex is essential for generating awareness.

claimClassic psychedelics initiate a cascade of altered neural connectivity and blood-flow across brain regions including the default-mode network (medial prefrontal cortex, posterior cingulate cortex, inferior parietal lobule, lateral temporal cortex, hippocampus, and precuneus), the amygdala, the thalamus, and the claustrum.
