“…In fact, the preSMA is an interface region between prefrontal and motor systems that is thought to facilitate motor responses to perceived (speech) sounds, such as sub-vocal articulation (Lima, Krishnan, & Scott, 2016). Furthermore, connectivity between IFG and preSMA via the frontal aslant tract has been associated with verbal fluency and speech initiation (Catani et al, 2013;Dragoy et al, 2020), leading us to suggest that our result (Eickhoff et al, 2005). a Clusters reported with lower FWE-correction: L anterior insula: p = .062, R fusiform gyrus: p = .091, and L pre-supplementary motor area: p = .060.…”

Future studies should further explore the role of the IFG‐preSMA interaction in intonation perception and production, and its generalisability across tonal and non‐tonal languages.…”

Language comprehension depends on tight functional interactions between distributed brain regions. While these interactions are established for semantic and syntactic processes, the functional network of speech intonationthe linguistic variation of pitchhas been scarcely defined. Particularly little is known about intonation in tonal languages, in which pitch not only serves intonation but also expresses meaning via lexical tones. The present study used psychophysiological interaction analyses of functional magnetic resonance imaging data to characterise the neural networks underlying intonation and tone processing in native Mandarin Chinese speakers. Participants categorised either intonation or tone of monosyllabic Mandarin words that gradually varied between statement and question and between Tone 2 and Tone 4. Intonation processing induced bilateral fronto-temporal activity and increased functional connectivity between left inferior frontal gyrus and bilateral temporal regions, likely linking auditory perception and labelling of intonation categories in a phonological network. Tone processing induced bilateral temporal activity, associated with the auditory representation of tonal (phonemic) categories. Together, the present data demonstrate the breadth of the functional intonation network in a tonal language including higher-level phonological processes in addition to auditory representations common to both intonation and tone.

“…Such multifaceted involvement of the left inferior frontal gyrus in linguistic processes may explain why its activation was the most statistically robust. The posterior superior frontal gyrus (premotor to supplementary motor cortex) was likely activated as part of the dorsal route supporting articulation (Hickok & Poeppel, 2007) or speech initiation (Dragoy et al, 2020, Kinoshita et al, 2014).…”

To avoid post-neurosurgical language deficits, intraoperative mapping of the language function in the brain can be complemented with preoperative mapping with fMRI. The validity of an fMRI language localizer paradigm crucially depends on the choice of an optimal language task and baseline condition. This study presents a new fMRI language localizer in Russian using overt sentence completion, a task that comprehensively engages the language function by involving both production and comprehension at the word and sentence level. The paradigm was validated in 18 neurologically healthy volunteers who participated in two scanning sessions, for estimating test-retest reliability. For the first time, two baseline conditions for the sentence completion task were compared. At the group level, the paradigm significantly activated both anterior and posterior language-related regions. Individual-level analysis showed that activation was elicited most consistently in the inferior frontal regions, followed by posterior temporal regions and the angular gyrus. Test-retest reliability of activation location, as measured by Dice coefficients, was moderate and thus comparable to previous studies. Test-retest reliability was higher in the frontal than temporo-parietal region and with the most liberal statistical thresholding compared to two more conservative thresholding methods. Lateralization indices were expectedly left-hemispheric, with greater lateralization in the frontal than temporo-parietal region, and showed moderate test-retest reliability. Finally, the pseudoword baseline elicited more extensive and more reliable activation, although the syllable baseline appears more feasible for future clinical use. Overall, the study demonstrated the validity and reliability of the sentence completion task for mapping the language function in the brain. The paradigm needs further validation in a clinical sample of neurosurgical patients. Additionally, the study contributes to general evidence on test-retest reliability of fMRI.

“…Stimulation studies first linked the left FAT to speech production using picture naming paradigms, inducing stuttering in patients when stimulation was applied (Kinoshita et al, 2015). More recently, intraoperative work has demonstrated that the left FAT is linked to the production of sentences rather than single words, indicating a key role in planning, timing and coordination of speech (Chernoff et al, 2019;Dragoy et al, 2020). A role in planning is supported by findings in healthy adults that linked interindividual variation in macrostructural features of this tract with lexical decision making (Vallesi & Babcock, 2020).…”

Attention, working memory, and executive control are commonly considered distinct cognitive functions with important reciprocal interactions. Lesion studies pioneered by Donald Stuss have demonstrated both overlap and dissociation in their behavioral expression and anatomical underpinnings. Here, we provide an overview of cognitive models as well as recent data from lesion studies and both invasive and noninvasive multimodal neuroimaging and brain stimulation, in order to provide an updated perspective on the relationship between attention, working memory, and executive control. Specifically, we address the functional and anatomical correspondence between these processes, toward the goal of identifying whether a lower dimensional theoretical framework should be employed to understand executive control (Karolis et al., 2019). We conclude by emphasizing that one avenue for moving the field, pioneered by Donald Stuss, forward consists of studying this low-dimensional space with a multi-method approach to identify converging evidence regarding the interaction between subfunctions, allowing to construct a model of executive control as the emergent consequence of efficient implementation of these processes.
