Posterior Superior Temporal Sulcus

Individuals improve with practice on a variety of perceptual tasks, presumably reflecting plasticity in underlying neural mechanisms. We trained observers to discriminate biological motion from scrambled (nonbiological) motion and examined whether the resulting improvement in perceptual performance was accompanied by changes in activation within the posterior superior temporal sulcus and the fusiform “face area,” brain areas involved in perception of biological events. With daily practice, initially naive observers became more proficient at discriminating biological from scrambled animations embedded in an array of dynamic “noise” dots, with the extent of improvement varying among observers. Learning generalized to animations never seen before, indicating that observers had not simply memorized specific exemplars. In the same observers, neural activity prior to and following training was measured using functional magnetic resonance imaging. Neural activity within the posterior superior temporal sulcus and the fusiform “face area” reflected the participants' learning: BOLD signals were significantly larger after training in response both to animations experienced during training and to novel animations. The degree of learning was positively correlated with the amplitude changes in BOLD signals.

Posterior Superior Temporal Sulcus

Understanding the sequence (i.e. word order) of linguistic input plays an important role in sentence comprehension, particularly in languages such as English (Bornkessel-Schlesewsky et al., 2015). Neuroimaging and clinical research shows that left posterior superior temporal sulcus (pSTS) contributes towards sequence processing in both linguistic and non-linguistic contexts (Bornkessel et al., 2005; Wilson et al., 2010). To test the causal contribution of left pSTS for sequence-dependent sentence processing, we applied image-guided low-frequency repetitive transcranial magnetic stimulation (1 Hz for 15 minutes at 90% resting motor threshold) to this region in 23 healthy native English speakers. Participants undertook an auditory sentence processing task and were asked to identify the sentential actor or undergoer. Sentences were either semantically plausible or were rendered implausible by an animacy violation (e.g. “The student will write the answer” versus “The answer will write the student”). After sham-rTMS (control condition), participants predominantly selected the first noun as the actor and second noun as the undergoer, relying strongly on sequence cues (word order) for interpretation as expected in English speakers. By contrast, after real-rTMS, participants were more likely to use animacy as a cue to interpretation, with higher selections of the animate noun as the actor and inanimate noun as the undergoer regardless of word order. This effect also interacted with question focus and response time. These results indicate that sequence-based language processing is reduced after low-frequency rTMS to pSTS, suggesting a role for pSTS in processing sequential aspects of language such as word order.

Posterior Superior Temporal Sulcus

AbtractRecognizing the identity of a person is fundamental to guide social interactions. We can recognize the identity of a person looking at her face, but also listening to her voice. An important question concerns how visual and auditory information come together, enabling us to recognize identity independently of the modality of the stimulus. This study reports converging evidence across univariate contrasts and multivariate classification showing that the posterior superior temporal sulcus (pSTS), previously known to encode polymodal visual and auditory representations, encodes information about person identity with invariance within and across modality. In particular, pSTS shows selectivity for faces, selectivity for voices, classification of face identity across image transformations within the visual modality, and classification of person identity across modality.
