Noninvasive functional and neuroanatomical exploration of the human basal ganglia with high resolution (7T) MRI
The basal ganglia receive inputs from virtually the entire cerebral cortex. The anatomy of the basal ganglia and its well-position in the circuitry give these structures a crucial role in influencing many neural pathways and the information processing systems. Due to this role, basal ganglia functions have remained elusive for a long time. The aim of this project is to study the function, structure and connectivity of the basal ganglia with high-field high-resolution (7T) MRI, and, to investigate its role and influence on information processing when predictions based on experience or previous cues do not match the actual context.
Extraction and analysis of temporal acoustic cues in patients with temporal lobe lesions
We investigate the effect of pitch pattern and order violations in speech on different temporal and segmental levels. For this purpose, we use lesion mapping and connectivity measures as well as EEG to compare the ERP responses of patients with temporal lobe lesions and healthy controls.
Hierarchical rhythm in auditory language and music
To date, metric and periodic aspects of rhythm have been inconsistently defined and yet indiscriminately compared across language and music studies. This project seeks a unified account of rhythm perception, with specific regard to its role in syntax processing across the two domains using EEG and EEG-oscillatory measures.
The impact of metric cues on semantic processing
We examine the influence of configural rhythms at different semantic levels using EEG and fMRI. Our main interest concerns the facilitation of lexical semantic integration by means of predictable metric cues.
The effects of metric regularity on emotion and aesthetic perception
We utilize EEG, EEG-oscillatory measures and fMRI to explore to what extent rhythmic predictability facilitates poetry comprehension and intensifies affective states in listeners.
Attentional orienting to emotional sounds
Anna S. Hasting
This project aims to identify the relative impact of evolutionary and experience-based factors on attentional orienting to emotional human and animal vocalizations as well as positive, negative and neutral environmental sounds. Two ERP studies look into the temporal processing stages influenced by these factors. In an fMRI study, we further explore whether distinct brain areas are involved in attentional orienting to emotional vocalizations of related versus familiar species.
Predictive processes underlying emotion perception and their neural correlates
Hao Tam Ho
Perception cannot solely be sensory driven but must be guided by top-down predictive mechanisms. The importance of emotions in human communication necessitates that emotional information is processed fast and efficiently, in particular, when the perceiver is faced with information from multiple sources (e.g. voice, facial expression, semantics etc.). In a series of ERP and fMRI studies we probe the magnitude of such top-down influences on multisensory perception of emotions and to uncover the neural correlates of this interaction.
