Many studies refer to the relevance of metric cues in speech segmentation during language acquisition and adult language processing. However, the on-line use (i.e., time-locking the unfolding of a sentence to EEG) of metric stress patterns that are manifested by the succession of stressed and unstressed syllables during auditory syntactic processing has not(More)
While the primary function of the basal ganglia (BG) is linked to motor behaviour, several investigations of non-motor behaviour allocate cognitive and language-specific functions to the BG. What may such seemingly discrepant functions have in common? Some neurophysiologic theories of motor behaviour assign temporal sequencing, others the sequencing of(More)
Recent research suggests that the brain routinely binds together information from gesture and speech. However, most of this research focused on the integration of representational gestures with the semantic content of speech. Much less is known about how other aspects of gesture, such as emphasis, influence the interpretation of the syntactic relations in a(More)
Temporal regularity allows predicting the temporal locus of future information thereby potentially facilitating cognitive processing. We applied event-related brain potentials (ERPs) to investigate how temporal regularity impacts pre-attentive and attentive processing of deviance in the auditory modality. Participants listened to sequences of sinusoidal(More)
In stress-timed languages, the alternation of stressed and unstressed syllables (or 'meter') is an important formal and temporal cue to guide speech processing. Previous electroencephalography studies have shown that metric violations result in an early negative event-related potential. It is unclear whether this 'metric' negativity is an N400 elicited by(More)
Physical activity has been shown to enhance circulating brain-derived neurotrophic factor (BDNF) in animals and humans. However, the exact time course and sex-specific modulation of peripheral BDNF in response to exercise are still poorly understood. We examined the kinetics of BDNF serum concentrations in response to perceived high-intensity and(More)
Rhythm is a phenomenon that fundamentally affects the perception of events unfolding in time. In language, we define 'rhythm' as the temporal structure that underlies the perception and production of utterances, whereas 'meter' is defined as the regular occurrence of beats (i.e. stressed syllables). In stress-timed languages such as German, this regularity(More)
In the current event-related potential (ERP) study, we investigated how speech rhythm impacts speech segmentation and facilitates the resolution of syntactic ambiguities in auditory sentence processing. Participants listened to syntactically ambiguous German subject- and object-first sentences that were spoken with either regular or irregular speech rhythm.(More)
The current work set out to answer three questions: (1) Are reported syntactic deficits in patients with structural damage to the basal ganglia (BG) in the cortico-striato-thalamo-cortical systems (CSTCS) the result of a syntax specific computational deficit or are they potentially a consequence of a generalized timing deficit? (2) Do BG patients suffer(More)
