Functional organization of the human superior temporal sulcus
… strongly implicated in social perception: the superior temporal sulcus (STS). In Chapter 2, I assess the overall functional organization of STS responses to different types of social stimuli, using fMRI. I find that the STS comprises a number of functionally specific subregions that process …

Face perception : the relationship between identity and expression processing
… controls. The fusiform face area and posterior superior temporal sulcus showed sensitivity for both identity and expression changes. Independent sensitivity for identity and expression changes was observed in the precuneus and middle superior temporal sulcus respectively. Finally, we explored …

Neurale Mechanismen "intuitiver" Urteilsprozesse
… and anteromedial prefrontal regions, in the temporal cortex, precuneus, and right cerebellum. Although no explicit solution was found, these regions were already active in the implicit condition, indicating that the implicit perception of semantic coherence is primarily based on the same …

The Effect of Intranasal Oxytocin on Neural Functioning in Widow(er)s
… inferior frontal gyrus, the precuneus, and right superior temporal sulcus (STS). During INT OT, the CG group uniquely demonstrated slowed reaction time across all stimulus types. The NCG group during INT OT showed increased activation in the superior temporal sulcus (STS) and right inferior …

The Neural Correlates of Guilt and Restitution During a Social Decision Making Task
… BOLD signal in the amygdala, insula, and the superior temporal sulcus. The present results are consistent with past studies that indicate an important role of the vlPFC and mPFC for processing aversive social cues and to resolve decision conflict.

ON THE ROLE OF VOCAL EMOTIONS FOR VERBAL MEMORY: AN INVESTIGATION OF NEURAL AND PSYCHOPHYSIOLOGICAL MECHANISMS
… and greater activity in the bilateral superior temporal gyrus, superior temporal sulcus and right transverse temporal gyrus. At test, words previously heard with a sad prosody were remembered less accurately and rated more negatively than their neutral counterparts. A greater HR …

The Effect of Social Interaction on the Neural Correlates of Language Processing and Mentalizing
… with narrative processing and mentalizing (i.e., temporal parietal junction). Regions associated with intentionality understanding (i.e., posterior superior temporal sulcus) were more active when mentalizing about a live partner. These results have implications for quantifying and understanding …

What functional magnetic resonance imaging can tell us about theory of mind
… action, including a region of posterior superior temporal sulcus (the pSTS-VA). In chapters 3 and 4, I consider the implications of these and other neuroimaging results for the mental structure of theory of mind, based on proposals derived from developmental psychology and philosophy.

Neural signatures of ethnic in-group bias in observing dynamic social interactions
… approach behaviors. Third, the posterior superior temporal sulcus and nucleus accumbens showed sensitivity to in-group handshakes, which was also linked to the positive impact of handshakes on in-group evaluations. Overall, these findings shed light on the mechanisms underlying intergroup …

Neural representations used by brain regions underlying speech production
… bilateral frontal operculum and left posterior superior temporal sulcus (pSTs). Behavioral learning measures correlated with increased response for novel sequences in the frontal operculum and with white matter integrity under the pSTs, implicating functional and structural connectivity of these …

Pattern codes for perceived gaze direction revealed by functional MRI
… demonstrated that single cells in macaque superior temporal sulcus (STS) are tuned to specific directions of social cues, including gaze direction, head view, and body posture. Furthermore, a subset of such neurons respond to a single direction across multiple cues, suggesting that the code …

Interrogating the infant mind with fMRI
… that face-selective responses in infant FFA, superior temporal sulcus (STS), and medial prefrontal cortex (MPFC) emerge in parallel indicating that as early as infants can detect and perceive a face, they also attribute social meaning to that face. My thesis then interrogates the origin of …

The Neural Substrates of Multisensory Speech Perception
… (fMRI) experiments have implicated the posterior superior temporal sulcus (STS) in auditory-visual integration of both speech and non-speech stimuli. While evidence from prior imaging studies have found increases in STS activity for audiovisual speech compared with unisensory auditory or visual …

Neural basis of private and social decision-making: new insights from transcranial ultrasound stimulation and multivariate analysis
… temporoparietal junction (TPJ), the posterior superior temporal sulcus (pSTS), and the precuneus, while observational learning additionally recruits the PCC and more anterior regions, including the rmPFC, the central orbitofrontal cortex (cOFC), and the dorsolateral prefrontal cortex (dlPFC). …

Effects of Social and Non-Social Interpretations of Complex Images on Human Eye Movement and Brain Activation
… imaging revealed that a region of the right superior temporal sulcus was selectively activated by the social condition compared to the non-social condition, an area known for its role in social tasks. Brain activation in response to the non-social condition was located in many of the same …

Neural Correlates of Audiovisual Speech Perception In Aphasia and Healthy Aging
… evidence to suggest that neurons within the left superior temporal sulcus (STS) provide a critical neural hub for the integration of auditory and visual information in speech. While most studies of audiovisual processing focus on neural mechanisms within healthy, young adults, we currently know …

Neurobiological mechanisms of hallucinations in schizophrenia
… mechanism characterized by fronto-temporal and insular grey matter reductions, I turn to the contribution of cortical sulcation, a product of second and third trimester neurodevelopmental processes, which has been robustly implicated in schizophrenia pathology, and, more recently, …

Specialized Signals for Spatial Attention in the Ventral and Dorsal Visual Streams
… it is known that face-selective regions in the superior temporal sulcus (STS) show enhanced responses to facial motion that are absent in the rest of the face-processing system. In macaques, face areas also exist, but their functional specializations for facial motion are unknown. We showed …

Hierarchical organisation of voice and voice gender perception

Multisensory Integration in adults with Attention-Deficit/Hyperactivity Disorder
