Patients with semantic dementia (SD), a neurodegenerative disease affecting the anterior temporal lobes (ATL) (1), present with striking cognitive deficits: they can have difficulties naming objects and familiar people from both pictures and descriptions (2, 3). Furthermore, SD patients make semantic errors (e.g., naming "horse" a picture of a zebra), suggesting that their impairment affects object knowledge rather than lexical retrieval. Because SD can affect object categories as disparate as artifacts, animals, and people, as well as multiple input modalities, it has been hypothesized that ATL is a semantic hub (4) that integrates information across multiple modality-specific brain regions into multimodal representations. With a series of converging experiments using multiple analysis techniques, Wang et al. (5) test the proposal that ATL is a semantic hub in the case of person knowledge, investigating whether ATL: (i) encodes multimodal representations of identity, and (ii) mediates the retrieval of knowledge about people from representations of perceptual cues.Wang et al. (5) asked 50 participants to learn biographical information (name, age, marital status, occupation, city of residence, and the appearance of their house as presented in a photograph) about four fictitious people over 2 d of training. On the third day, participants completed an fMRI experiment in which they were shown images of the four people's faces (pictured from different viewpoints with respect to the training), their names (written in a different font and color), their houses (pictured from different viewpoints), and images of objects associated with their occupation. Multimodal representations of person identity were probed in a set of regions-of-interest (ROIs), training a support vector machine to classify between different face identities, and testing it to classify between the associated names, houses, and occupation-related objects. All four classifications were significant in the ATL, and none of the classifications was significant in any of the other ROIs, showing that ATL representations of person identity generalize across a variety of stimulus types. The ATL has been previously shown to encode information about face identity (6), generalizing across facial expressions (7), viewpoints (8), and face parts (9).The ATL has also been implicated in the association of names and faces with knowledge about people (10, 11). Wang et al.'s (5) classification results are an important extension of this work, revealing representations of identity that generalize across faces, names, and objects associated with one individual.In the ATL-hub hypothesis, the ATL acts as an intermediary for the linkage of different kinds of knowledge represented in specialized brain regions. To test this proposal, in a second study, Wang et al. (5) defined a set of ROIs showing stronger responses when retrieving information about a person compared with a resting baseline. The contrast identified as ROIs the left ATL, hippocampus, posterior cingulate (PCC), i...
