This attenuation has been explained as a result of motor relevant processing. The current study shows that corresponding somatosensory inputs can also change the auditory processing of a self-generated sound. We recorded auditory event-related potentials (ERP) in response to self-generated sounds and assessed how the amount of auditory attenuation changed according to the somatosensory inputs. The sound stimuli were generated by a finger movement that pressed on a virtual object, which was produced by a haptic robotic device. Somatosensory inputs were modulated by changing the stiffness of this virtual object (low and high) in an unpredictable manner. For comparison purposes, we carried out the same test with a computer keyboard, which is conventionally used to induce the auditory attenuation of self-generated sound. While N1 and P2 attenuations were clearly induced in the control condition with the keyboard as has been observed in previous studies, when using the robotic device the amplitude of N1 was found to vary according to the stiffness of the virtual object. The amplitude of N1 in the low stiffness condition was similar to that found using the keyboard for the same condition but not in the high stiffness condition. In addition, P2 attenuation did not differ between stiffness conditions. The waveforms of auditory ERP after 200 ms also differed according to the stiffness conditions. The estimated source of N1 attenuation was located in the right parietal area. These results suggest that somatosensory inputs during movement can modify the auditory processing of self-generated sound. The auditory processing of self-generated sound may represent self-referenced processing like an embodied process or an action-perception mechanism.</p>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":" ","pages":"109103"},"PeriodicalIF":2.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143531555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While fMRI studies have characterised the MD network's role in cognitive demand, linking these findings to electrophysiological activity remains a critical challenge. This article discusses the potential of oscillatory and aperiodic neural activity to bridge this gap. Although recent meta-analyses highlight mid-frontal theta power as a robust marker of task demand, its localised spatial distribution, limited cross-task generalisability, and potential confounds from aperiodic components limit its ability to fully represent the MD network. In contrast, aperiodic activity, particularly broadband power, has emerged as a strong candidate for indexing task demand due to its robust decoding performance and cross-task generalisability in response to diverse task demands, and spatial overlap with MD regions. Aperiodic activity may reflect fundamental neural properties, such as spiking rates and excitation/inhibition (E/I) balance, and is scale-free and exists across modalities, positioning it as a promising mechanism underpinning domain-general cognitive control that links to the MD network. Meanwhile, multiplexed low-frequency oscillations (e.g., delta and theta) may implement inter-regional synchronisation within the MD network, enabling large-scale coordination between MD subregions that supports cognitive control. Together, this article proposes a hypothetical framework linking the MD network to electrophysiological responses: Aperiodic broadband power, potentially reflecting population-level spiking activity, may support activation within MD regions, while multiplexed low-frequency oscillatory synchronisations may mediate inter-regional connectivity between MD regions.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"210 ","pages":"Article 109096"},"PeriodicalIF":2.0,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143449591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-four younger and twenty-five older adults underwent functional imaging while viewing videos of four emotions and indicating the emotion expressed. Using multivariate analysis (Partial Least Squares), we found that older adults engaged a similar network for both anger and pride, while younger adults recruited two separate networks for positive vs. negative emotions, regardless of whether the emotion was basic or social. Furthermore, older adults with higher stress scores and younger adults with higher depression scores, as measured by the Depression, Anxiety, Stress Scale (DASS-21), activated a similar brain network during recognition of embarrassment. These findings suggest that both pride and anger are emotionally salient and require similar cognitive and attentional resources in older adults, while younger adults’ neural activity is modulated by the valence, rather than the social content of stimuli.

In Experiment 1 (attended ensemble changes), observers attended to ensembles and reported rare changes of their mean orientation, while fixating on a central cross.

This can be framed as highly efficient action emulation, but the neural underpinnings of this remain elusive. We examined the neural processes linked to the training effect of athletes (4000 h of training) by employing a continuous pursuit tracking task and EEG data. We manipulated feedback availability by intermittently occluding the cursor. As a performance measure, we used the distance between cursor and target (position error), the angle between the cursor and target movement direction (direction error) and the magnitude of cursor acceleration (acceleration error) to quantify movement strategy. In EEG data, we investigated beta, alpha, and theta frequency band oscillations. Athletes' position error is lower than non-athletes’ when there is no feedback about the cursor location, but direction error is not. We found no quantitative power differences in the investigated frequency bands, but evidence that athletes and non-athletes accomplish action emulation through different functional neuroanatomical structures, especially when alpha and beta band activity is concerned. We surmise that non-athletes seemed to rely on top-down inhibitory control to predict guesses on cursor trajectories in the absence of cursor position feedback. In contrast, athletes might benefit from enhanced inhibitory gating mechanisms in the ventral stream and the integration of sensory and motor processes in the insular cortex, which could provide them with processing advantages in computing forward models. We further reflect that this advantage might be supported by alpha band activity in athletes' motor cortex, suggesting less inhibitory gating and a higher likelihood of executing integrated sensorimotor programs. We posit that current framings of neuroanatomical structures and neurophysiological processes in the action emulation framework must be revised to better capture superior motor performance.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"209 ","pages":"Article 109085"},"PeriodicalIF":2.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143080723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a modified Sternberg paradigm, alpha power was initially found to increase at the anticipation of strong compared to weak distractors, reflecting the active gating of distracting information from interfering with the memory trace. However, there was a lack of evidence supporting the inhibition account of alpha oscillations in later studies using similar experimental design with greater temporal disparity between the encoding phase and the presentation of the distractors. This temporal disparity might have dampened the demands for inhibition. To test the hypothesis that alpha inhibition takes place when distractors are temporally close to the encoding phase, here we designed a modified Sternberg paradigm where distractors were sandwiched between targets in the encoding phase to ensure that they compete for working memory resources. Using electroencephalography (EEG), we replicated the finding that alpha power increased for strong compared to weak distractors. The effect was present throughout the encoding phase, not only upon the presentation of distractors but also before and after the presentation of distractors, providing evidence for both proactive and reactive inhibition of distractors at the neuronal level. Meanwhile, the effect was restricted to the context of high but not low target-to-distractor ratio.

The accumulating evidence indicates that cooperative settings foster higher levels of creativity compared to individual settings, suggesting that social factors play a role in creativity.In this review, we synthesize the findings on individual and group creativity and propose a new brain model for understanding group creativity. We extend the twofold model of creativity and suggest that creativity in social setting involves an interplay between idea generation, social influence and flexibility. Building on this model we suggest that group creativity is mediated by activity as well as interbrain coupling in neural circuits associated with associative thinking (default mode network), flexibility (executive control network) and observation-execution (inferior frontal gyrus). By shifting the focus from isolated individuals to social settings, we can gain a more comprehensive understanding of creativity and its neural mechanisms.

For yaw, an initial view-specific representation was evident in the convolutional layers, but a view-symmetric representation emerged in the fully-connected layers.
