“…For auditory language perception, specialized left and right hemispheric involvement has been reported, with the left hemispheric (LH) perisylvian cortex supporting the processing of semantic and syntactic information (Friederici, 2002), and with the perisylvian cortex of the right hemisphere (RH) being responsible for processing prosodic information (Meyer et al, 2002;Zatorre et al, 2002). These experimental data suggest a model for adult language comprehension that assumes segmental information to be processed predominantly in LH and suprasegmental information to be processed primarily in RH .…”

Temporal dynamics of perisylvian activation during language processing in children and adults

The perisylvian region of the human cortex is known to play a major role in language processing. Especially the superior temporal cortex (STC) and the inferior frontal cortex (IFC) have been investigated with respect to their particular involvement in language comprehension. In the present research, the timing of recruitment of these language-related brain areas in both hemispheres was examined as a function of age using functional imaging data of 6-year-old children and adults with a special focus on blood oxygenation level dependent (BOLD) response time courses. The results show that children's activation time courses differ from that of adults. First, children show an overall later peak of BOLD responses. Second, children's IFC responds much later than their STC, while in adults the difference between both regions is less pronounced. Within the STC, both groups show similar regionally U-shaped activation patterns with fastest peaks in voxels at the STC's mid-portion around Heschl's gyrus and longer latencies in anterior and posterior directions, suggesting a coarsely similar information flow in adults and children in the temporal region. Finally, children in contrast to adults, display a temporal primacy of right over left hemispheric activation. The observed overall latency differences between children and adults are in line with the assumption of ongoing maturation in perisylvian brain regions and the connections between them. A functional perspective on BOLD timing argues for a developmental change from higher processing costs in children compared to adults due to slower and less automatic language processes, in particular those located in the IFC. The observed hemispheric differences are discussed in the context of developmental models assuming a high reliance on right-hemisphere-based suprasegmental information processing during language comprehension in childhood.

“…These authors argued that many of the asymmetries in both audition and vision result from a preferred role for the left and right hemispheres in processing relatively high and low frequencies, respectively, in the senses of both pitch and spatial frequency. The hemispheric asymmetry within the dimension of time has been developed by many authors, including Ackermann and Riecker (2004), Allard and Scott (1975), Deacon (1997), Ivry and Robertson (1998, Chapter 6), Tallal (1980), and Zatorre, Belin, and Penhune, (2002). We shall refer to this idea as the Asymmetric Sampling in Time (AST) theory, the name ascribed to it by Poeppel (2003).…”

Two priming experiments demonstrated exogenous attentional persistence to the fundamental auditory dimensions of frequency (Experiment 1) and time (Experiment 2). In a divided-attention task, participants responded to an independent dimension, the identification of three-tone sequence patterns, for both prime and probe stimuli. The stimuli were specifically designed to parallel the local-global hierarchical letter stimuli of [Navon D. (1977). Forest before trees: The precedence of global features in visual perception. Cognitive Psychology, 9, 353-383] and the task was designed to parallel subsequent work in visual attention using Navon stimuli [Robertson, L. C. (1996). Attentional persistence for features of hierarchical patterns. Journal of Experimental Psychology: General, 125, 227-249; Ward, L. M. (1982). Determinants of attention to local and global features of visual forms. Journal of Experimental Psychology: Human Perception and Performance, 8,[562][563][564][565][566][567][568][569][570][571][572][573][574][575][576][577][578][579][580][581]. The results are discussed in terms of previous work in auditory attention and previous approaches to auditory local-global processing.

“…For example, it has been suggested that F 0 is processed in the right hemisphere, while intensity and duration are processed in the left hemisphere (e.g., Van Lancker & Sidtis, 1992;Zatorre, Belin, & Penhune, 2002). Note moreover, that these lateralization patterns are possibly independent of whether prosody is emotional or linguistic (e.g., Ouellette & Baum, 1993;Zatorre, 1988).…”

On the lateralization of emotional prosody: An event-related functional MR investigation

et al. 2003

In order to investigate the lateralization of emotional speech we recorded the brain responses to three emotional intonations in two conditions, i.e., ''normal'' speech and ''prosodic'' speech (i.e., speech with no linguistic meaning, but retaining the Ôslow prosodic modulationsÕ of speech). Participants listened to semantically neutral sentences spoken with a positive, neutral, or negative intonation in both conditions and judged how positive, negative, or neutral the intonation was on a five-point scale. Core peri-sylvian language areas, as well as some frontal and subcortical areas were activated bilaterally in the normal speech condition. In contrast, a bilateral fronto-opercular region was active when participants listened to prosodic speech. Positive and negative intonations elicited a bilateral fronto-temporal and subcortical pattern in the normal speech condition, and more frontal activation in the prosodic speech condition. The current results call into question an exclusive right hemisphere lateralization of emotional prosody and expand patient data on the functional role of the basal ganglia during the perception of emotional prosody.
