“…In general, our findings show that ARHL influences theta oscillations at earlier time points on a visual cognitive control task. Our findings align with other studies, both human ( Heinrichs-Graham et al, 2022 ; Ryan et al, 2023 ) and animal ( Johne et al, 2022 ), which have shown that hearing loss modulates oscillatory activity in the theta band. However, adequate comparison of our findings with others is difficult since we used a visual task while most have examined theta activity in relation to auditory tasks, primarily SiN recognition ( Doelling et al, 2014 ; Hyafil et al, 2015 ; Etard and Reichenbach, 2019 ).…”

IntroductionEmerging evidence suggests changes in several cognitive control processes in individuals with age-related hearing loss (ARHL). However, value-directed strategic processing, which involves selectively processing salient information based on high value, has been relatively unexplored in ARHL. Our previous work has shown behavioral changes in strategic processing in individuals with ARHL. The current study examined event-related alpha and theta oscillations linked to a visual, value-directed strategic processing task in 19 individuals with mild untreated ARHL and 17 normal hearing controls of comparable age and education.MethodsFive unique word lists were presented where words were assigned high- or low-value based on the letter case, and electroencephalography (EEG) data was recorded during task performance.ResultsThe main effect of the group was observed in early time periods. Specifically, greater theta synchronization was seen in the ARHL group relative to the control group. Interaction between group and value was observed at later time points, with greater theta synchronization for high- versus low-value information in those with ARHL.DiscussionOur findings provide evidence for oscillatory changes tied to a visual task of value-directed strategic processing in individuals with mild untreated ARHL. This points towards modality-independent neurophysiological changes in cognitive control in individuals with mild degrees of ARHL and adds to the rapidly growing literature on the cognitive consequences of ARHL.

“…Prior work has identified the key neural oscillations involved in Gf, which include theta, alpha, and gamma oscillations in frontoparietal regions [25][26][27][28][29][30], with some studies showing that the strength of oscillations in these regions scales with greater cognitive demands and effort [31,32]. Further, oscillatory responses in the PFC and parietal cortices have been shown to support more optimal performance in tasks involving Gf [27,28], thus underscoring the critical role oscillations play in the long-range communication and integration of the distributed networks serving these higher-order cognitive processes [32][33][34].…”

Background. Chronic stress is associated with a multitude of psychopathological disorders that share similar alterations in neural dynamics and symptomatology. Applying the National Institute of Mental Health’s Research Domain Criteria (RDoC) framework, we probed the stress-diathesis model by identifying how a transdiagnostic psychosocial distress index representing high-dimensional patterns of stress-related aberrations was coupled to the neural oscillatory dynamics serving abstract reasoning. Methods. The sample consisted of 69 adults (mean age=44.77 years, SD=13.66) who completed the NIH Toolbox Emotion Battery (NIHTB-EB) and a matrix reasoning task during magnetoencephalography (MEG). A transdiagnostic psychosocial distress index was computed using exploratory factor analysis with assessments from the NIHTB-EB. Whole-brain correlations were conducted using the resulting psychosocial distress index for each oscillatory response, and the resulting peak voxels were extracted for mediation analyses to assess the degree to which neural oscillatory activity mediates the interplay between perceived stress and psychosocial distress. Results. We found that elevated psychosocial distress was associated with blunted oscillatory alpha/beta and gamma responses in key cortical association regions. Further, we found that only alpha/beta activity in the right superior temporal sulcus partially mediated the relationship between perceived stress and psychosocial distress. Conclusions. The present study is among the first to couple perceived stress and psychosocial distress with alterations in oscillatory activity during a matrix reasoning task. These findings illuminate the relationship between perceived stress and neural alterations associated with psychopathology.

“…Briefly, we applied HD-tDCS and then collected high-density magnetoencephalography (MEG) during performance of an established abstract reasoning task. This abstract reasoning task was adapted from Raven's Progressive Matrices and has been shown to be tightly linked to classic measures of Gf (Raven & Raven, 2003;Heinrichs-Graham et al, 2022;Taylor et al, 2020Taylor et al, , 2022. Previous studies that stimulated the parietal cortices have shown improved abstract reasoning performance following stimulation compared to the sham condition, although these studies used theta frequency tACS and relatively small samples (Neubauer et al, 2017;Pahor & Jaušovec, 2014).…”

Fluid intelligence (Gf) involves rational thinking skills and requires the integration of information from different cortical regions to resolve novel complex problems. The effects of non‐invasive brain stimulation on Gf have been studied in attempts to improve Gf, but such studies are rare and the few existing have reached conflicting conclusions. The parieto‐frontal integration theory of intelligence (P‐FIT) postulates that the parietal and frontal lobes play a critical role in Gf. To investigate the suggested role of parietal cortices, we applied high‐definition transcranial direct current stimulation (HD‐tDCS) to the left and right parietal cortices of 39 healthy adults (age 19–33 years) for 20 min in three separate sessions (left active, right active and sham). After completing the stimulation session, the participants completed a logical reasoning task based on Raven's Progressive Matrices during magnetoencephalography. Significant neural responses at the sensor level across all stimulation conditions were imaged using a beamformer. Whole‐brain, spectrally constrained functional connectivity was then computed to examine the network‐level activity. Behaviourally, we found that participants were significantly more accurate following left compared to right parietal stimulation. Regarding neural findings, we found significant HD‐tDCS montage‐related effects in brain networks thought to be critical for P‐FIT, including parieto‐occipital, fronto‐occipital, fronto‐parietal and occipito‐cerebellar connectivity during task performance. In conclusion, our findings showed that left parietal stimulation improved abstract reasoning abilities relative to right parietal stimulation and support both P‐FIT and the neural efficiency hypothesis. imageKey points Abstract reasoning is a critical component of fluid intelligence and is known to be served by multispectral oscillatory activity in the fronto‐parietal cortices. Recent studies have aimed to improve abstract reasoning abilities and fluid intelligence overall through behavioural training, but the results have been mixed. High‐definition transcranial direct‐current stimulation (HD‐tDCS) applied to the parietal cortices modulated task performance and neural oscillations during abstract reasoning. Left parietal stimulation resulted in increased accuracy and decreased functional connectivity between occipital regions and frontal, parietal, and cerebellar regions. Future studies should investigate whether HD‐tDCS alters abstract reasoning abilities in those who exhibit declines in performance, such as healthy ageing populations.
