How the human brain exchanges information across sensory modalities to recognize other people 下载免费PDF全文
Recognizing the identity of other individuals across different sensory modalities is critical for successful social interaction. In the human brain, face‐ and voice‐sensitive areas are separate, but structurally connected. What kind of information is exchanged between these specialized areas during cross‐modal recognition of other individuals is currently unclear. For faces, specific areas are sensitive to identity and to physical properties. It is an open question whether voices activate representations of face identity or physical facial properties in these areas. To address this question, we used functional magnetic resonance imaging in humans and a voice‐face priming design. In this design, familiar voices were followed by morphed faces that matched or mismatched with respect to identity or physical properties. The results showed that responses in face‐sensitive regions were modulated when face identity or physical properties did not match to the preceding voice. The strength of this mismatch signal depended on the level of certainty the participant had about the voice identity. This suggests that both identity and physical property information was provided by the voice to face areas. The activity and connectivity profiles differed between face‐sensitive areas: (i) the occipital face area seemed to receive information about both physical properties and identity, (ii) the fusiform face area seemed to receive identity, and (iii) the anterior temporal lobe seemed to receive predominantly identity information from the voice. We interpret these results within a prediction coding scheme in which both identity and physical property information is used across sensory modalities to recognize individuals.

Mental illness is a significant cause of disability worldwide, including here in the United States. Given the shortage of trained mental health professionals, a significant portion of patients needing care are managed in the primary care setting. Accountable Care Organizations (ACOs), for example, are seeking to improve the quality of care for this vulnerable population, but many are facing significant challenges relating to integration of new services. We sought to elucidate barriers faced by primary care practitioners (PCPs)—physicians, physician trainees and nurse practitioners—at a New York primary care clinic, which impede delivery of optimal care to those suffering from mental illness. The study was conducted with 32 PCPs in 2016–2017 at Mount Sinai Internal Medicine Associates in New York City. For the quantitative component of the study, a 54-item questionnaire was devised to assess their attitude, behavior and confidence in managing psychiatric patients. For the qualitative component, data was obtained from 3 open-ended questions. Responses were coded for salient themes. Analysis revealed a range of difficulties faced by PCPs. Overall, participants felt that the need to integrate mental health care into primary care was important, however they reported significant barriers in terms of lack of time, lack of resources, low confidence in treating more complex mental health conditions and difficulties with referring patient to mental health specialists. Despite a growing body of evidence that integration of mental health services in primary care leads to improved outcomes, addressing barriers to care will be key to ensuring feasibility of integration measures. 相似文献
