Face-selective and voice-selective brain regions have been shown to represent face-identity and voice-identity, respectively. Here we investigated whether there are modality-general person-identity representations in the brain that can be driven by either a face or a voice, and that invariantly represent naturalistically varying face videos and voice recordings of the same identity. Models of face and voice integration suggest that such representations could exist in multimodal brain regions, and in unimodal regions via direct coupling between face- and voice-selective regions. Therefore, in this study we used fMRI to measure brain activity patterns elicited by the faces and voices of familiar people in face-selective, voice-selective, and person-selective multimodal brain regions. We used representational similarity analysis to (1) compare representational geometries (i.e. representational dissimilarity matrices) of face- and voice-elicited identities, and to (2) investigate the degree to which pattern discriminants for pairs of identities generalise from one modality to the other. We did not find any evidence of similar representational geometries across modalities in any of our regions of interest. However, our results showed that pattern discriminants that were trained to discriminate pairs of identities from their faces could also discriminate the respective voices (and vice-versa) in the right posterior superior temporal sulcus (rpSTS). Our findings suggest that the rpSTS is a person-selective multimodal region that shows a modality-general person-identity representation and integrates face and voice identity information.

Interference with the FREEDOM or PERSONAL AUTONOMY of another person, with justifications referring to the promotion of the person's good or the prevention of harm to the person. (from Cambridge Dictionary of Philosophy, 1995); more generally, not allowing a person to make decisions on his or her own behalf.
Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
A person's concept of self as being male and masculine or female and feminine, or ambivalent, based in part on physical characteristics, parental responses, and psychological and social pressures. It is the internal experience of gender role.
