“…This connectivity would therefore allow cingulo-opercular cortex to share information about performance outcomes, task difficulty, and the value in exerting control (cingulate: Carter et al 1998, 2000; Botvinick et al 1999, 2004; Kerns et al 2004; Kerns 2006; Shenhav et al 2013) in order to increase arousal through autonomic function (anterior insula: Hoffman & Rasmussen 1953; Meyer et al 2004; Cechetto 2014), increase response cautiousness or response inhibition (right inferior frontal cortex: Wager et al 2005; Chambers et al 2007; Goghari & MacDonald 2009; Hughes et al 2013; Aron et al 2014), and guide controlled retrieval or response selection (left inferior frontal cortex: Thompson-Schill et al 1997; D’Esposito et al 1999; Sohn et al 2003; Moss et al 2005; Goghari & MacDonald 2009; Davey et al 2015). …”

Is Listening in Noise Worth It? The Neurobiology of Speech Recognition in Challenging Listening Conditions

This review examines findings from functional neuroimaging studies of speech recognition in noise to provide a neural systems level explanation for the effort and fatigue that can be experienced during speech recognition in challenging listening conditions. Neuroimaging studies of speech recognition consistently demonstrate that challenging listening conditions engage neural systems that are used to monitor and optimize performance across a wide range of tasks. These systems appear to improve speech recognition in younger and older adults, but sustained engagement of these systems also appears to produce an experience of effort and fatigue that may affect the value of communication. When considered in the broader context of the neuroimaging and decision making literature, the speech recognition findings from functional imaging studies indicate that the expected value, or expected level of speech recognition given the difficulty of listening conditions, should be considered when measuring effort and fatigue. We propose that the behavioral economics and/or neuroeconomics of listening can provide a conceptual and experimental framework for understanding effort and fatigue that may have clinical significance.

“…Executive control over knowledge activation is vital for successful semantic cognition, yet the neural basis of this function is not well understood. In particular, functional neuroimaging studies have focused almost exclusively on the contribution of left inferior frontal gyrus (LIFG; Thompson-Schill et al, 1997; Badre and Wagner, 2007), while neuropsychological investigations (Jefferies and Lambon Ralph, 2006, Noonan et al, 2010, Corbett et al, 2009), neuroimaging meta-analyses (Noonan et al, 2013), and studies using inhibitory transcranial magnetic stimulation (TMS, Whitney et al, 2011, Whitney et al, 2012 and Davey et al, 2015), point to the possibility of a large-scale distributed network underpinning semantic control.…”

Charting the effects of TMS with fMRI: Modulation of cortical recruitment within the distributed network supporting semantic control

Semantic memory comprises our knowledge of the meanings of words and objects but only some of this knowledge is relevant at any given time. Thus, semantic control processes are needed to focus retrieval on relevant information. Research on the neural basis of semantic control has strongly implicated left inferior frontal gyrus (LIFG) but recent work suggests that a wider network supports semantic control, including left posterior middle temporal gyrus (pMTG), right inferior frontal gyrus (RIFG) and pre-supplementary motor area (pre-SMA). In the current study, we used repetitive transcranial magnetic stimulation (1 Hz offline TMS) over LIFG, immediately followed by fMRI, to examine modulation of the semantic network. We compared the effect of stimulation on judgements about strongly-associated words (dog-bone) and weaker associations (dog-beach), since previous studies have found that dominant links can be recovered largely automatically with little engagement of LIFG, while more distant connections require greater control. Even though behavioural performance was maintained in response to TMS, LIFG stimulation increased the effect of semantic control demands in pMTG and pre-SMA, relative to stimulation of a control site (occipital pole). These changes were accompanied by reduced recruitment of both the stimulated region (LIFG) and its right hemisphere homologue (RIFG), particularly for strong associations with low control requirements. Thus repetitive TMS to LIFG modulated the contribution of distributed regions to semantic judgements in two distinct ways.

“…The regions belonging to such a broad network for abstract representation of actions include the dorsal and ventral premotor cortex (Calvo-Merino, Glaser, Grezes, Passingham, & Haggard, 2005;Tai, Scherfler, Brooks, Sawamoto, & Castiello, 2004;Wade & Hammond, 2015), superior and inferior parietal lobule (Buccino, et al, 2001;Gardner, Goulden, & Cross, 2015), angular gyrus (Davey, et al, 2015;Farrer, et al, 2008;Lui, et al, 2008), supramarginal gyrus (Abreu, et al, 2012;Pokorny, et al, 2015), and superior temporal sulcus (Alaerts, et al, 2015; see also Cattaneo & Rizzolatti, 2009). …”

The neural correspondence between the systems responsible for the execution and recognition of actions has been suggested both in humans and non-human primates. Apart from being a key region of this visuo-motor observation-execution matching (OEM) system, the human inferior frontal gyrus (IFG) is also important for speech production. The functional overlap of visuo-motor OEM and speech, together with the phylogenetic history of the IFG as a motor area, has led to the idea that speech function has evolved from pre-existing motor systems and to the hypothesis that an OEM system may exist also for speech. However, visuo-motor OEM and speech OEM have never been compared directly. We used electrocorticography to analyze oscillations recorded from intracranial electrodes in human fronto-parieto-temporal cortex during visuo-motor (executing or visually observing an action) and speech OEM tasks (verbally describing an action using the first or third person pronoun). The results show that neural activity related to visuo-motor OEM is widespread in the frontal, parietal, and temporal regions. Speech OEM also elicited widespread responses partly overlapping with visuo-motor OEM sites (bilaterally), including frontal, parietal, and temporal regions. Interestingly a more focal region, the inferior frontal gyrus (bilaterally), showed both visuo-motor OEM and speech OEM properties independent of orolingual speech-unrelated movements. Building on the methodological advantages in human invasive electrocorticography, the present findings provide highly precise spatial and temporal information to support the existence of a modalityindependent action representation system in the human brain that is shared between systems for performing, interpreting and describing actions.
