“…The left anterior insula furthermore has not only been related to articulatory speech programming [Dronkers, 1996] and to automatization of lexical retrieval [Van Turennout et al, 2000], but also to auditory speech processing and verbal working memory [Augustine, 1996]. Ackermann and Riecker [2004] suggested that the anterior insular cortex is involved in speech-motor control because they found no activity in covert speech. Similarly, we did not find strong activity in the insula in the covert-naming condition.…”

Speakers use external auditory feedback to monitor their own speech. Feedback distortion has been found to increase activity in the superior temporal areas. Using fMRI, the present study investigates the neural correlates of processing verbal feedback without distortion. In a blocked design, the following conditions were presented: (1) overt picture-naming, (2) overt picture-naming while pink noise was presented to mask external feedback, (3) covert picture-naming, (4) listening to the picture names (previously recorded from participants' own voices), and (5) listening to pink noise. The results show that auditory feedback processing involves a network of different areas related to general performance monitoring and speech-motor control. These include the cingulate cortex and the bilateral insula, supplementary motor area, bilateral motor areas, cerebellum, thalamus and basal ganglia. Our findings suggest that the anterior cingulate cortex, which is often implicated in error-processing and conflict-monitoring, is also engaged in ongoing speech monitoring. Furthermore, in the superior temporal gyrus, we found a reduced response to speaking under normal feedback conditions. This finding is interpreted in the framework of a forward model according to which, during speech production, the sensory consequence of the speech-motor act is predicted to attenuate the sensitivity of the auditory cortex.

“…Our results, however, suggest that their roles in stuttering may be different. During normal speech, the insula was found to constribute to the actual coordination of articulatory movement (Ackermann and Riecker, 2004). Importantly, the right insula also has a similar role as the left tempo-parietal region, i.e., the AG (BA39), in aiding the coordination and evaluation of task performance across behavioral tasks with varying perceptual and response demands (Eckert et al, 2008).…”

a b s t r a c t a r t i c l e i n f oUsing an fMRI-based classification approach and the structural equation modeling (SEM) method, this study examined the neural bases of atypical planning and execution processes involved in stuttering. Twelve stuttering speakers and 12 controls were asked to name pictures under different conditions (single-syllable, multi-syllable, or repeated-syllable) in the scanner. The contrasts between conditions provided information about planning and execution processes. The classification analysis showed that, as compared to nonstuttering controls, stuttering speakers' atypical planning of speech was evident in their neural activities in the bilateral inferior frontal gyrus (IFG) and right putamen and their atypical execution of speech was evident in their activations in the right cerebellum and insula, left premotor area (PMA), and angular gyrus (AG). SEM results further revealed two parallel neural circuits-the basal ganglia-IFG/PMA circuit and the cerebellum-PMA circuit-that were involved in atypical planning and execution processes of stuttering, respectively. The AG appeared to be involved in the interface of atypical planning and execution in stuttering. These results are discussed in terms of their implications to the theories about stuttering and to clinical applications.

“…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.
