Narratives are useful stimuli for studying this phenomenon, as the flow of information and the way we make meaning of them mirrors how we comprehend and make sense of our daily lives. Many studies have investigated the segmentation of audiovisual stimuli, such as movies, but only a handful of studies focused on how the brain parses auditory-only narrative. Using two stories with rich narrative features, we asked participants to listen to the story-recordings while being scanned with fMRI. We then recruited two separate groups of behavioral participants to parse the stories, either via transcript (visual-only) or recording (audio-only). Annotated boundaries from the two modalities were analyzed and used as behavioral benchmarks for the neural-behavioral comparison of event structures. We examined four regions of interest (angular gyrus, posterior cingulate cortex, early auditory cortex, and early visual cortex) and found that only the angular gyrus produced neural event structures that significantly matched with the behavioral event structures across both modalities and both stories. Our results indicate that activity in the angular gyrus is associated with the neural processes involved in parsing continuous narratives, particularly when these narratives are audio-only and contain ambiguous event transitions, rather than with changes in sensory-related features.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"185 ","pages":"Pages 286-300"},"PeriodicalIF":3.2,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we addressed this gap by testing the effects of frontoparietal theta synchronization and desynchronization on impulsive decision making using transcranial alternating current stimulation (tACS). Healthy participants performed an intertemporal choice task and a 3-back working memory task while left frontal and parietal cortices were stimulated with a 5 Hz theta frequency at in-phase (synchronization), anti-phase (desynchronization), or sham tACS. We found frontoparietal in-phase theta tACS to improve working memory performance, while in the decision task anti-phase tACS was associated with more impulsive choices and stronger hyperbolic discounting of future rewards.

Here, we simultaneously test body ownership and sense of agency in EDs compared to controls by exploiting different rubber hand illusion (RHI) paradigms (i.e., classic visuo-tactile, passive and active visuo-motor versions). In any RHI versions, no differences in the susceptibility to the illusion between EDs patients and controls emerged at the body ownership questionnaire, thus suggesting a normal multisensory integration mechanism. Crucially, correlation analysis revealed that a higher level of body dissatisfaction is associated with increased susceptibility to RHI, as measured by the body ownership questionnaire. Interestingly, patients with a bulimic variant of EDs reported agency toward the fake hand in the visuo-tactile RHI, revealing an abnormal sense of agency in absence of voluntary movement. Moreover, in the visuo-motor RHI, EDs patients exhibited a proprioceptive drift both in synchronous and asynchronous conditions. Hence, our results revealed a dissociation between explicit and implicit RHI measures, showing a more plastic bodily-self representation when the RHI enlists hand movements, leading to a stronger visual-capture of proprioception.

Thirty-five participants were recruited to investigate the relationship between pain perception and ongoing oscillations as well as the factors likely to modulate them, combining a sustained periodic thermonociceptive stimulation paradigm including periodic oddball events with a frequency-tagging analysis approach. Oddballs were delivered either at a higher or lower intensity (“high oddball” versus “low oddball” condition) than baseline stimuli. Continuous ratings of pain perception were collected during the stimulation to track participants' perception. Despite the stimuli being barely perceived as painful (hence relating predominantly to thermonociception), the continuous ratings of perception clearly reflected the variations of stimulus intensity, but only in the “high oddball” condition. Consistently, the oddball stimulus modulated ongoing oscillations in the “high oddball”, but not in the “low oddball” condition. Because of the lack of differentiation between baseline and oddball cycles in the “low oddball” condition – both in perception and at the neural level – these findings do not allow disentangling the differential effects of stimulus intensity and saliency on the perception of thermonociceptive stimuli, or on the modulation of oscillatory activities related to thermonociception. However, they indicate the modulation of ongoing oscillations reflects subjects' perception of thermonociceptive stimuli that are both salient and intense.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"185 ","pages":"Pages 316-335"},"PeriodicalIF":3.2,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a newly designed propositional speech production paradigm, we examined how semantic distractors of varying levels of relatedness affect propositional speech performance in healthy adults. In the paradigm, participants were assessed on their ability to formulate verbal responses while distracted by semantically related or unrelated words, simulating real-world scenarios with meaningful auditory distractions (e.g., sounds from radio programs). We also examined the cognitive processes associated with task performance. We recruited 30 younger participants (mean age: 22.23 years) and 27 older participants (mean age: 75.31 years) matched for sex, handedness, and intelligence. All participants were screened using the Montreal Cognitive Assessment (MoCA) and neuropsychological assessments. Older adults performed better than younger adults on a semantic memory task, but performed poorer on tasks assessing executive functions, including interference control, verbal response initiation and suppression, and semantic verbal fluency. In the novel propositional speech production task, older adults exhibited a pronounced semantic interference effect (F_{1.58, 83.67} = 4.67, <em>p</em> = .018, ηp² = .08; with MoCA as a covariate), particularly for concrete distractors, resulting in longer response latencies compared to associative and unrelated distractors (Bonferroni-corrected P-values &lt;.01). Exploratory correlation analyses revealed that longer response latencies in the propositional speech production task were associated with a poorer performance on neuropsychological tests tapping verbal response suppression (false discovery rate-corrected <em>p</em> &lt; .05). Our findings suggest that verbal communication difficulties in the context of environmental distractions experienced by older adults could be due to the semantic interference effect. Cognitive interventions aimed at enhancing inhibitory control could be beneficial to older adults in maintaining their social engagement in the later life.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"185 ","pages":"Pages 229-239"},"PeriodicalIF":3.2,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we asked whether changes in the visuo-tactile PPS maps occur during the planning of a goal directed foot-movement. We asked participants to respond to the location of a tactile stimulus delivered to the index finger (top) or the thumb (bottom) of the right hand while ignoring a visual distractor presented at congruent or incongruent elevations, either close to the foot or close to the goal of the foot movement. This version of the cross-modal congruency task was performed under two different experimental conditions, as a baseline (static task, no movement involved) and embedded into a dual-task in which participants also had to plan and execute a goal-directed foot movement (dynamic task). In the static task, comparable cross-modal congruency effects (CCE) were present near the foot and near the movement goal. In the dynamic task, the CCE near the foot shrank considerably, whereas a sizable CCE was present near the movement goal. This anticipatory reweighting of the multisensory representation of near-space demonstrates that PPS is modulated by the intention to perform a goal-directed foot movement, with a weakened representation of the space around the currently occupied foot location when a movement is imminent.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"185 ","pages":"Pages 170-183"},"PeriodicalIF":3.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143591680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have investigated complex stopping behaviours, such as response-selective stopping where only one component of a bimanual action requires cancellation. A current emphasis has been to use electromyographical (EMG) recordings to assess the temporal dynamics of action inhibition at the level of the muscle, beyond those based solely on observable behavioural events. Here, we combine EMG and behavioural data from 17 cohorts of healthy younger and older adults yielding over 42,000 response-selective stopping trials, providing unique insights into this emerging field. Expanding from past research in this area, our robust single-trial EMG analyses permit detection of cancelled (partial) and response-generating EMG bursts in both hands, revealing substantial overlaps in the distributions of timing of action cancellation and re-programming. These findings are consistent with recent experimental and modelling evidence, suggesting that response-selective stopping is best modelled as two independent processes: a discrete bimanual stop and initiation of a <em>new</em> unimanual response. This overlap may be incompatible with the recent pause-then-cancel model, and more consistent with a broader “pause-then-retune” account, where a slower process mediates any action updating, not just cancellation. Moreover, this independence means that cancellation can happen at any time during motor planning and execution, against the notion of an observable “point of no return” in terms of EMG and behavioural measures. We also discuss best practices for the analysis of EMG data and indicate how methodological aspects, such as choosing appropriate reference time points, can influence the outcomes and their interpretation.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"185 ","pages":"Pages 211-228"},"PeriodicalIF":3.2,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143591682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
