    Humans display a strong tendency to make spontaneous inferences concerning the thoughts and intentions of others. Although this ability relies upon the concerted effort of multiple brain regions, the dorsal medial prefrontal cortex (DMPFC) is most closely associated with the ability to reason about other people's mental states and form impressions of their character. Here, we investigated this region's putative social category preference using fMRI as 34 participants engaged in uninstructed viewing of a complex naturalistic stimulus. Using a data-driven “reverse correlation” approach, we characterize the DMPFC's stimulus response profile from ongoing neural responses to a dynamic movie stimulus. Results of this analysis demonstrate that the DMPFC's response profile is dominated by the presence of scenes involving social interactions between characters. Subsequent content analysis of video clips created from this response profile confirmed this finding. In contrast, regions of the inferotemporal and parietal cortex were selectively tuned to faces and actions, both features that often covary with social interaction but may be difficult to disentangle using standard event-related approaches. Together, these findings suggest that the DMPFC is finely tuned for processing social interaction above other categories and that this preference is maintained during unrestricted viewing of complex natural stimuli such as movies.

    "Finally, a study published in the Journal of Neuroscience found that introverts had larger, thicker gray matter in their prefrontal cortex — the area of the brain associated with abstract thought and decision-making. Extroverts had thinner gray matter in that same area. This suggests that introverts may devote more neural resources to abstract thought, while extroverts tend to live in the moment more."

    "The inner ring: abstract versus concrete

    According to Keirsey, everyone can engage in both observation and introspection. When people touch objects, watch a basketball game, taste food, or otherwise perceive the world through their senses, they are observant. When people reflect and focus on their internal world, they are introspective. However, individuals cannot engage in observation and introspection at the same time. The extent to which people are more observant or introspective directly affects their behavior.

    People who are generally observant are more 'down to earth.' They are more concrete in their worldview and tend to focus on practical matters such as food, shelter, and their immediate relationships. Carl Jung used the word sensation when describing people who prefer concrete perception. People who are generally introspective are more 'head in the clouds.' They are more abstract in their world view and tend to focus on global or theoretical issues such as equality or engineering. Carl Jung used the word intuition when describing people who prefer abstract conception."

    "rmPFC [BA 10, BA 24 (the pregenual anterior cingulate cortex), and BA 32 (the pregenual anterior cingulate cortex)]."

    "The rmPFC, which lies between the vmPFC and the dmPFC, has unique and privileged anatomical features because of its widespread anatomical connections with many cortical and subcortical structures including the brainstem, the insula, and most of the other mPFC subregions (Dixon et al., 2017). This region has been implicated in various functions such as default-mode processing (Uddin et al., 2009; Andrews-Hanna et al., 2010), far-sighted decisions, where one needs to choose between immediate smaller and delayed more substantial reward (Kable and Glimcher, 2007), and, most notably, cognitive branching, that is, pursuing a long-term mental plan by tracking the values of ongoing and alternative behavioral strategies and switching to the better option (Koechlin and Hyafil, 2007; Mansouri et al., 2017).

    BA 10 interacts with both FPN 1 and FPN 2 (vlPFC etc).

    My current view is that a type should be defined by three dominant large-scale brain networks (or subsystems).

    FN/the frontopolar network (active vs. inactive), DAN, VAN, CON 1 (mirror neurons), CON 2 (the ventral stream), FPN 1, FPN 2, DMN 1 (dmPFC), DMN 2 (vmPFC)

    "the FPCN network includes regions of the dorsolateral and dorsal medial PFC, as well as dACC"

    "DAN and DMN are associated with attention to perceptual features of the environmental or stored representational knowledge respectively. The FPCN is active for both attention states, suggesting that this network may play a modulatory role in shifting the focus of attention."



    https://www.pnas.org/content/115/7/E1598


    "The frontoparietal control network (FPCN) contributes to executive control, the ability to deliberately guide action based on goals. While the FPCN is often viewed as a unitary domain general system, it is possible that the FPCN contains a fine-grained internal organization, with separate zones involved in different types of executive control. Here, we use graph theory and meta-analytic functional profiling to demonstrate that the FPCN is composed of two separate subsystems: FPCNA is connected to the default network and is involved in the regulation of introspective processes, whereas FPCNB is connected to the dorsal attention network and is involved in the regulation of perceptual attention. These findings offer a distinct perspective on the systems-level circuitry underlying cognitive control."

    https://en.wikipedia.org/wiki/Salience_network

    "The cingulo-opercular network (CO) has generally been equated with the salience network, but it may represent a distinct but adjacent network or a part of the SN. The CO may involve more dorsal areas, while the SN involves more ventral and rostral areas of the anterior insula and medial frontal cortex containing von Economo neurons. The CO is sometimes also referred to as the cingulo-insular network.

    The ventral attention network (VAN), also known as the ventral frontoparietal network (VFN) or ventral attention system (VAS), has also been equated with the SN. The VAN is commonly defined as a right-hemisphere-dominant network involving the temporoparietal junction and the ventral frontal cortex that responds to unexpected salient stimuli. Some have defined it as a larger, bilateral network that is a combination of the SN and CO, while others have described it as a part of the salience network involving the more dorsal anterior insular cortex.

    In 2019, Uddin et al. proposed that midcingulo-insular network (M-CIN) be used as a standard anatomical name for the network that includes the SN, CO, and VAN."

    The dorsal and ventral attention networks are involved in goal-directed executive control processes and salience evaluations respectively, which are necessary operations for the control of spatial attention and the orientation of attention to a specific area of interest. The ventral attention network (VAN) includes the temporoparietal junction, the supramarginal gyrus, the frontal operculum, and the anterior insula. The focus of the VAN is primarily upon allocentric space, or knowing about objects that lie beyond immediate reach, including information about what those objects are used for. The dorsal attention network (DAN) is anchored in the intraparietal sulcus and the frontal eye fields. The DAN includes a focus upon egocentric space to generate sensory-motor information about functions such as reaching, grasping, the “data” that are important for knowing about how to use objects.
