The posterior superior temporal sulcus is involved in social communication not specific for the eyes

摘要: Neuroimaging and lesion studies suggest that the superior temporal sulcus (STS) region is involved in eye gaze processing. Hence, STS suggested to be location of "eye-direction detector", a key element "mindreading model" proposed by Baron-Cohen [Baron-Cohen, S. (1995). Mindblindness: An essay on autism theory mind. Cambridge: The MIT Press]. Not only eyes, but also pointing finger another person can inform us about direction attention other one. In an event-related functional magnetic resonance imaging experiment, healthy human subjects actively followed directional cue provided either eyes or, alternatively, make movement toward object space. Our results show clearly posterior equally processing information from source. difference between two cues was found lingual gyrus, which stronger blood-oxygen-level-dependent (BOLD) response observed during compared following task. We different structures might initial coming or finger. These streams may then converge region, orchestrating usage wider range socially relevant able intentions person.
