The phase resetting hypothesis proposes that the envelope-tracking response is generated by resetting the phase of intrinsic nonlinear neural oscillations, whereas the evoked response hypothesis proposes that the envelope-tracking response is the linear superposition of transient responses evoked by a sequence of acoustic events in speech. Recent studies have demonstrated a linear phase property of the envelope-tracking response, supporting the evoked response hypothesis. However, the cortical regions aligning with the evoked response hypothesis remain unclear. To address this question, we directly recorded from the cortex using stereo-electroencephalography (SEEG) in nineteen epilepsy patients as they listened to natural speech, and we investigated whether the phase lag between the speech envelope and neural activity linearly changes across frequency. We found that the linear phase property of low-frequency (LF) (.5–40 Hz) envelope tracking was widely observed in Heschl’s gyrus (HG) and superior temporal gyrus (STG), with additional sparser distribution in insula, postcentral gyrus, and precentral gyrus. Furthermore, the latency of LF envelope-tracking responses derived from phase–frequency curve exhibited an increase gradient along HG and in the posterior-to-anterior direction in STG. Our findings suggest that auditory cortex can track speech envelope in line with the evoked response hypothesis.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"186 ","pages":"Pages 1-10"},"PeriodicalIF":3.2,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679722","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}

Naturalistic action errors in this population are often attributed to limb apraxia, a common deficit in the representation and performance of object-related actions. However, naturalistic action impairments are also observed in right hemisphere stroke and traumatic brain injury, populations infrequently associated with apraxia, and errors across all these populations are influenced by overall severity. Based on these and other data, an alternative (though not mutually exclusive) account is that naturalistic action errors in individuals with LCVA are also a consequence of deficits in general attentional resource availability or allocation. In this study, we conducted a retrospective analysis of data from a group of 51 individuals with LCVA who had completed a test of naturalistic action, along with a battery of tests assessing praxis, attention allocation and control, reasoning, and language abilities to determine which of these capacities contribute uniquely to naturalistic action impairments. Using a regularized regression method, we found that naturalistic action impairments are predicted by both praxis deficits (hand posture sequencing and gesture recognition), as well as attention allocation and control deficits (orienting and dividing attention), along with language comprehension ability and age. Using support vector regression-lesion symptom mapping, we demonstrated that naturalistic action impairments are associated with lesions to posterior middle temporal gyrus and anterior inferior parietal lobule regions known to be implicated in praxis; as well the middle frontal gyrus that has been implicated in both praxis and attention allocation and control. Together, these findings support the hypothesis that naturalistic action impairments in people with LCVA are a consequence of apraxia as well as deficits in attention allocation and control.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"185 ","pages":"Pages 301-315"},"PeriodicalIF":3.2,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679638","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}

This rescaling implies that the brain possesses a representation of the physical size of the stimulated body part. However, it remains unclear whether long-term visual deprivation could affect tactile size constancy and body distortions. To answer this question, we asked blind and sighted individuals to estimate tactile distances between pairs of touched points delivered on the dorsum of their hands and fingers. The results showed that, regardless of visual experience, both groups of participants showed typical hand distortions, suggesting that even a lack of visual information since birth does not influence the spatial representation of tactile stimulation.

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.

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.

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).
