“…Left planum temporale and posterior superior temporal gyrus play critical roles in processing of speech (Jiang et al, 2023; Mesgarani et al, 2014; Möttönen et al, 2006), while right inferior frontal sulcus, angular gyrus and supramarginal gyrus have key roles in processing of speech in non-ideal listening conditions, selective attention to auditory features and domain-general resolution of competing sensory signals (Davis & Johnsrude, 2003; Golden et al, 2015; Jiang et al, 2021, 2023; Lemaitre et al, 2018; Szameitat et al, 2006). The right temporo-parietal junction has also been implicated in matching sensory inputs with internal representations, and attentional reorientation of unexpected stimuli (Bae et al, 2021). The right superior parietal lobules are functionally more typically associated with somatosensory and visuomotor processing (Gamberini et al, 2020; Wang et al, 2015), but have also previously been implicated in dichotic listening studies (Kompus et al, 2012), possibly reflecting their role in spatial processing and attentional allocation across sensory modalities (Vandenberghe et al, 2001; Wu et al, 2007).…”

Hearing is multifaceted and the relative contributions of peripheral and central hearing loss are rarely considered together in the context of dementia. Here, we assessed peripheral (as measured with pure-tone audiometry) and central (as measured with dichotic listening) hearing in 19 patients with typical amnestic Alzheimer′s disease (tAD), 10 patients with logopenic variant primary progressive aphasia (lvPPA), 11 patients with nonfluent/agrammatic variant PPA (nfvPPA), 15 patients with semantic variant PPA (svPPA), and 28 healthy age-matched individuals. Participants also underwent neuropsychological assessment and magnetic resonance image scanning, allowing us to use voxel-based morphometry to assess associations between hearing scores and grey matter volume. Dichotic listening was impaired in all patient groups relative to healthy controls. In the combined patient (but not healthy control) cohort, dichotic listening scores were significantly correlated with measures of global cognitive functioning and speech-based neuropsychological tasks. Pure-tone audiometry scores were not significantly elevated in any patient group relative to the healthy control group, and no significant correlations were observed between peripheral hearing and neuropsychological task performance in either the combined patient or healthy control cohorts. Neuroanatomically, dichotic listening performance was associated with grey matter volume in a bilateral fronto-temporo-parietal network over the combined patient cohort, but no correlates were identified for pure-tone audiometry. Our findings highlight the importance of speech parsing mechanisms beyond elementary sound detection in driving cognitive test performance, underline the importance of assessing central hearing alongside peripheral hearing in people with dementia, and further delineate the complex auditory profiles of neurodegenerative dementias.

“…Along with the role of attention reorienting, the TPJ participates in stimulus evaluation. It is argued to be activated in a sustained manner during the computation of the behavioral significance of the stimulus by comparing it with an internal representation ( Bae et al, 2021 ). The other role of TPJ (posterior subdivision)is connected to the so-called theory of mind ability associated with the attribution of thoughts, intentions, and beliefs to an opponent.…”

IntroductionThe brain mechanisms of deceptive behavior are relatively well studied, and the key brain regions involved in its processing were established. At the same time, the brain mechanisms underlying the processes of preparation for deception are less known.MethodsWe studied BOLD-signal changes during the presentation of the opponent’s feedback to a previous deceptive or honest action during the computer game. The goal of the game was to mislead the opponent either by means of deception or by means of telling the truth.ResultsAs a result, it was shown that several brain regions that were previously demonstrated as involved in deception execution, such as the left anterior cingulate cortex and anterior insula, also underlie processes related to deception preparation.DiscussionThe results obtained also allowed us to suggest that brain regions responsible for performance monitoring, intention assessment, suppression of non-selected solutions, and reward processing could be involved in shaping future action selection and preparation for deception. By shedding light on the brain mechanisms underlying deception, our study contributes to a deeper understanding of this complex cognitive process. Furthermore, it emphasizes the significance of exploring brain mechanisms governing the choice between deception and truth at various stages of decision-making.

“…Such evaluative processes might be commonly mediated by the MDN and the DMN [ 4 , 18 , 40 , 41 , 42 ]. Following or along with this evaluative process, the MDN might play a role in recruiting top-down processing resources to meet the task demands [ 18 , 40 , 43 ]. We suggest that it would be valuable to test this kind of specific hypotheses to clarify the functional roles of the DMN and MDN.…”

Adaptive behavior in the environment requires a high level of cognitive control to bias limited processing resources to behaviorally significant stimuli. Such control has been associated with a set of brain regions located in the fronto-parietal cortex (multiple demand network), whose activity was found to increase as the control demand for a task increases. In contrast, another set of regions, default mode network regions, were found to be deactivated during top-down processing of task stimuli. Despite this dissociation in their activation amplitudes, it is possible that activation patterns of these regions commonly encode specific task features. In two independent neuroimaging datasets, involving a total of 40 human samples, we found that the performance of an attentional task evoked positive activity of the MDN and deactivation of the DMN. Consistent with previous studies, task features could be decoded from the fronto-parietal cognitive regions. Importantly, the regions of the DMN also encoded task features when the task set had to be rapidly reconfigured in a transient, trial-by-trial manner, along with the MDN regions. These results suggest that the two separate brain networks ultimately co-ordinate for the effective establishment of top-down cognitive control.
