“…The IFG/IPL was less implicated in triggering the parieto-somato-motor network, whereas the STG/PM increased its driving force. This is testified by the connection that all components of the parieto-somato-motor network receive from the primary IC and is further corroborated by previous studies [Newman and Twieg, 2001;Rauschecker et al, 2008]. The processing of meaningless stimuli can only rely on bottom-up, sound-based analysis, sustained for longer times [Roy et al, 2008].…”

The act of listening to speech activates a large network of brain areas. In the present work, a novel data-driven technique (the combination of independent component analysis and Granger causality) was used to extract brain network dynamics from an fMRI study of passive listening to Words, Pseudo-Words, and Reverse-played words. Using this method we show the functional connectivity modulations among classical language regions (Broca's and Wernicke's areas) and inferior parietal, somatosensory, and motor areas and right cerebellum. Word listening elicited a compact pattern of connectivity within a parieto-somato-motor network and between the superior temporal and inferior frontal gyri. Pseudo-Word stimuli induced activities similar to the Word condition, which were characterized by a highly recurrent connectivity pattern, mostly driven by the temporal lobe activity. Also the Reversed-Word condition revealed an important influence of temporal cortices, but no integrated activity of the parieto-somato-motor network. In parallel, the right cerebellum lost its functional connection with motor areas, present in both Word and Pseudo-Word listening. The inability of the participant to produce the Reversed-Word stimuli also evidenced two separate networks: the first was driven by frontal areas and the right cerebellum toward somatosensory cortices; the second was triggered by temporal and parietal sites towards motor areas. Summing up, our results suggest that semantic content modulates the general compactness of network dynamics as well as the balance between frontal and temporal language areas in driving those dynamics. The degree of reproducibility of auditory speech material modulates the connectivity pattern within and toward somatosensory and motor areas.

“…Both regions are established contributors to speech production (Bohland & Guenther, 2006;Brendel et al, 2010;MacNeilage, 2008;Peeva et al, 2010;Penfield & Welch, 1951) but are nonetheless observed during purely receptive phonological working memory tasks (e.g., Awh et al, 1996;Rauschecker, Pringle, & Watkins, 2008;Strand et al, 2008). Both of these regions exhibited scaling response with increasing phonological working memory load in the present study as well, despite the purely receptive nature of the phonological working memory task.…”

Purpose: The primary purpose of this study was to identify the brain bases of phonological working memory (the shortterm maintenance of speech sounds) using behavioral tasks analogous to clinically sensitive assessments of nonword repetition. The secondary purpose of the study was to identify how individual differences in brain activation were related to participants' nonword repetition abilities. Method: We used functional magnetic resonance imaging to measure neurophysiological response during a nonword discrimination task derived from standard clinical assessments of phonological working memory. Healthy adult control participants (N = 16) discriminated pairs of real words or nonwords under varying phonological working memory load, which we manipulated by parametrically varying the number of syllables in target (non)words. Participants' cognitive and phonological abilities were also measured using standardized assessments. Results: Neurophysiological responses in bilateral superior temporal gyrus, inferior frontal gyrus, and supplementary motor area increased with greater phonological working memory load. Activation in left superior temporal gyrus during nonword discrimination correlated with participants' performance on standard clinical nonword repetition tests. Conclusion: These results suggest that phonological working memory is related to the function of cortical structures that canonically underlie speech perception and production. T he cognitive processes that underlie the short-term maintenance of language sounds are known collectively as phonological working memory. Phonological working memory is thought to support a wide range of linguistic behaviors, including novel word learning and vocabulary development, maintenance of information during sentence and discourse processing, and the acquisition of reading skill

“…The PMv activated during preferred rhythms and tempo and its adjacent areas, the inferior frontal gyrus and the Rolandic operculum, have been shown to be involved in voice-related tasks, such as singing [Ozdemir et al, 2006;Perry et al, 1999] and speech [Wildgruber et al, 1996], as well as singing imagery [Kleber et al, 2007;Riecker et al, 2000] and speech imagery [Rauschecker et al, 2008;Shergill et al, 2006]. The premotor activation we found most likely overlaps with the precentral area crucial for the control of learned vocal patterns, e.g.…”

“…Second, a motor imagery explanation cannot be reconciled with the absence of activation in dorsal premotor regions for neck and foot movements. And thirdly, there was no activity increase in areas characteristic for motor imagery and motor preparation such as the primary motor cortex, primary and secondary somatosensory areas, and especially the SMA/pre-SMA, an area which has been shown to be most reliably involved in vocal imagery [Kawashima et al, 2000;Kleber et al, 2007;Rauschecker et al, 2008;Riecker et al, 2000;Thobois et al, 2000]. Thus, it seems more consistent with the data to consider premotor involvement during preferred rhythms and tempo as an audiomotor fraction of vocal and articulatory representations that are exploited during attention to external rhythmic events.…”

Listening to music can induce us to tune in to its beat. Previous neuroimaging studies have shown that the motor system becomes involved in perceptual rhythm and timing tasks in general, as well as during preference-related responses to music. However, the role of preferred rhythm and, in particular, of preferred beat frequency (tempo) in driving activity in the motor system remains unknown. The goals of the present functional magnetic resonance imaging (fMRI) study were to determine whether the musical rhythms that are subjectively judged as beautiful boost activity in motor-related areas and if so, whether this effect is driven by preferred tempo, the underlying pulse people tune in to. On the basis of the subjects' judgments, individual preferences were determined for the different systematically varied constituents of the musical rhythms. Results demonstrate the involvement of premotor and cerebellar areas during preferred compared to not preferred musical rhythms and indicate that activity in the ventral premotor cortex (PMv) is enhanced by preferred tempo. Our findings support the assumption that the premotor activity increase during preferred tempo is the result of enhanced sensorimotor simulation of the beat frequency. This may serve as a mechanism that facilitates the tuning-in to the beat of appealing music.
