“…Sixty-one interleaved slices (3 × 3 × 2.5-mm voxels) were acquired aligned to 30°tilted from the anterior commissure-posterior commissure line, with full brain coverage. These imaging parameters (i.e., short TE, tilted slices) were optimized for mitigating susceptibility artifacts around ATL and OFC (72), and were validated by pilot scans as well as previous studies in the laboratory (10,28). In study 2, we adopted the same pulse sequence except the TR (2,000 ms) and 40 interleaved slices (3 × 3 × 3.5-mm voxels).…”

“…Here, we tested the hypothesis that a region in the anterior temporal lobe (ATL) has a function akin to a person identity node (1,9,10), subserving access to abstract person identity representations that can be retrieved from multiple cues, such as when you see a photo of Graceland and it cues your knowledge of Elvis (study 1). Next, we asked whether the ATL acts as a neural switchboard, performing in concert with other brain regions to enable the retrieval of different facets of person knowledge in a flexible and context-appropriate manner (study 2).…”

“…Next, we asked whether the ATL acts as a neural switchboard, performing in concert with other brain regions to enable the retrieval of different facets of person knowledge in a flexible and context-appropriate manner (study 2). We focus on the ATL because multiple lines of evidence from neuropsychology, electrophysiology, and neuroimaging have documented the critical role of the ATL in person identification (4, 5, 11-16), person-related learning (10,(17)(18)(19)(20)(21), semantic memory (6-8), and abstract social knowledge (1,(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33). Individuals with ATL damage due to resection or stroke have multimodal person recognition deficits (34), lose access to stored knowledge about familiar people (35,36), and have difficulties learning information about new people (4,22,37,38).…”

Social behavior is often shaped by the rich storehouse of biographical information that we hold for other people. In our daily life, we rapidly and flexibly retrieve a host of biographical details about individuals in our social network, which often guide our decisions as we navigate complex social interactions. Even abstract traits associated with an individual, such as their political affiliation, can cue a rich cascade of person-specific knowledge. Here, we asked whether the anterior temporal lobe (ATL) serves as a hub for a distributed neural circuit that represents person knowledge. Fifty participants across two studies learned biographical information about fictitious people in a 2-d training paradigm. On day 3, they retrieved this biographical information while undergoing an fMRI scan. A series of multivariate and connectivity analyses suggest that the ATL stores abstract person identity representations. Moreover, this region coordinates interactions with a distributed network to support the flexible retrieval of person attributes. Together, our results suggest that the ATL is a central hub for representing and retrieving person knowledge.person knowledge | anterior temporal lobe | person identity node | semantic memory | social neuroscience A s social creatures, it is essential that we develop a rich storehouse of knowledge about other members of our social network, such as who they are, how they look and sound, where they live, and what they do for a living. However, little is known about how and where such "person knowledge" is represented, stored, and retrieved in the brain. This inquiry is challenging because person knowledge is highly multimodal and multifaceted, being linked to both abstract features such as personality and social status as well as more concrete features such as eye color; in addition, familiar individuals are associated with detailed episodic and semantic memories (e.g., memories of shared experiences and biographic information) (1, 2). The neural circuit for person knowledge must therefore have the ability to combine multiple sources of information into an abstract representation accessible from multiplicative cues.An influential theory by Burton and Bruce (3) proposes that person recognition is achieved through a hierarchical process that begins with the activation of modality-specific recognition units that selectively respond to the presence of a known face, name, or voice. This information is then sent to an amodal person identity node (PIN) that integrates information from the modality-specific recognition units into a multimodal representation for that individual. Excitation of the PIN ultimately allows the retrieval of personspecific semantic information independently of stimulus modality (4, 5). A similar design is embedded in the "hub-and-spoke" theory of semantic knowledge, which proposes that different features of a concept (such as its color or taste) are distributed throughout the brain (the "spokes") and that a centralized "hub" integrates these features into a cohe...

Neural similarity between mentalizing and live social interaction during the transition to adolescence

Social interactions are essential for human development, yet little neuroimaging research has examined their underlying neurocognitive mechanisms using socially interactive paradigms during childhood and adolescence. Recent neuroimaging research has revealed activity in the mentalizing network when children engage with a live social partner, even when mentalizing is not required. While this finding suggests that social‐interactive contexts may spontaneously engage mentalizing, it is not a direct test of how similarly the brain responds to these two contexts. The current study used representational similarity analysis on data from 8‐ to 14‐year‐olds who made mental and nonmental judgments about an abstract character and a live interaction partner during fMRI. A within‐subject, 2 (Mental/Nonmental) × 2 (Peer/Character) design enabled us to examine response pattern similarity between conditions, and estimate fit to three conceptual models of how the two contexts relate: (1) social interaction and mentalizing about an abstract character are represented similarly; (2) interactive peers and abstract characters are represented differently regardless of the evaluation type; and (3) mental and nonmental states are represented dissimilarly regardless of target. We found that the temporal poles represent mentalizing and peer interactions similarly (Model 1), suggesting a neurocognitive link between the two in these regions. Much of the rest of the social brain exhibits different representations of interactive peers and abstract characters (Model 2). Our findings highlight the importance of studying social‐cognitive processes using interactive approaches, and the utility of pattern‐based analyses for understanding how social‐cognitive processes relate to each other.

The role of the ventrolateral anterior temporal lobes in social cognition

A key challenge for neurobiological models of social cognition is to elucidate whether brain regions are specialised for that domain. In recent years, discussion surrounding the role of anterior temporal regions epitomises such debates; some argue the anterior temporal lobe (ATL) is part of a domain‐specific network for social processing, while others claim it comprises a domain‐general hub for semantic representation. In the present study, we used ATL‐optimised fMRI to map the contribution of different ATL structures to a variety of paradigms frequently used to probe a crucial social ability, namely ‘theory of mind’ (ToM). Using multiple tasks enables a clearer attribution of activation to ToM as opposed to idiosyncratic features of stimuli. Further, we directly explored whether these same structures are also activated by a non‐social task probing semantic representations. We revealed that common to all of the tasks was activation of a key ventrolateral ATL region that is often invisible to standard fMRI. This constitutes novel evidence in support of the view that the ventrolateral ATL contributes to social cognition via a domain‐general role in semantic processing and against claims of a specialised social function.
