To this aim, two discriminative response tasks (DRTs) were employed: a feature DRT and a temporal (T-DRT). While the F-DRT required discrimination among different geometrical shapes, the T-DRT required discrimination among different stimulus durations. Specifically, this study investigated the role of premotor and prefrontal cortices, and sensory visual areas in preparatory activity preceding time-processing by electroencephalographic methods and analyzing the event-related potential (ERP). ERP components associated with motor (the BP), cognitive (the pN), and sensory readiness (the vN) were analyzed on 21 participants completing the two DRTs. The results support the involvement of all considered brain areas in temporal cognition but extend this information by indicating that these areas can be engaged during the preparation phase before the stimulus is delivered. Furthermore, the T-DRT requires strong anticipatory activity in the PFC likely serving as a moderator of upcoming motor responses. Finally, visual areas were greatly engaged in the early phase of sensory readiness of the T-DRT probably to create top-down low-level representations of imminent events to facilitate perception.</div></div>","PeriodicalId":55331,"journal":{"name":"Brain and Cognition","volume":"183 ","pages":"Article 106243"},"PeriodicalIF":2.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142787951","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}

Task-based functional connectivity revealed an interplay among specific left-brain regions – the middle temporal (MTG), inferior frontal (IFG), and supramarginal (SMG) gyri – during the processing of mechanical actions and physics principles, associating the activity of these areas with mechanical knowledge (SMG) and object-related semantic knowledge (MTG). Notably, the IFG was active during both types of processing, suggesting a critical role of this region in multi-modal information integration.

However, the underlying neural mechanisms involved in the cortical processing of proprioceptive input and its corresponding motor response are unclear. To address this issue, this study aims to investigate neuropsychological and neurophysiological performances using event-related potentials (ERP) on proprioceptive-motor tasks in young adults with pDCD.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Methods&lt;/h3&gt;&lt;div&gt;From a total of 149 young adults screened using the Bruininks-Oseretsky Test of Motor Proficiency 2nd Edition Complete Form (BOT-2), 12 individuals with pDCD were identified (mean age ± SD: 20.50 ± 1.08 years) along with 12 age- and sex-matched controls (mean age ± SD: 20.75 ± 1.05 years). Participants placed their dominant foot on a passive ankle motion apparatus that plantarflexed the ankle at a constant velocity of 22°/s for a total of 75 trials in each proprioceptive condition. With vision occluded, participants had to press the trigger button held by the dominant hand when they sensed the passive motion of the ankle (voluntary response, VR), or purely receive the movement without a voluntary response (non-voluntary response, NVR). Behavioral performances [i.e., mean movement detection time (MDT&lt;sub&gt;mean&lt;/sub&gt;), the standard deviation of the movement detection time (MDT&lt;sub&gt;SD&lt;/sub&gt;)] and ERP indices (i.e., N1, P3 amplitude, and latency) related to ankle kinesthetic stimuli were obtained to determine the proprioceptive-motor function.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;The results showed that young adults with pDCD exhibited longer MDT&lt;sub&gt;mean&lt;/sub&gt; (&lt;em&gt;p&lt;/em&gt; &lt; 0.001) and MDT&lt;sub&gt;SD&lt;/sub&gt; (&lt;em&gt;p&lt;/em&gt; = 0.002) compared to their controls.

The ERP differential measuring how much attention was allocated to the targets vs. distractors increased significantly with SES, independently of age. To explain these findings, we integrate the ear to the ground hypothesis and the socioenvironmental epigenetic stress approach. According to the ear to the ground hypothesis, frequent and prolonged environmental uncertainty and hazard induce low-SES children to learn adaptive over-vigilance, attending disproportionately to stimuli that are currently irrelevant but may quickly become relevant and thus require an immediate survival response. Socioenvironmental epigenetic stress refers to the bidirectional interaction between a stress-inducing environment and the impact and expression of transgenerational gene selections in low-SES contexts. Because low-SES individuals are historically under and misrepresented in research, the proposed framework contributes to increase our understanding of how socioeconomic and environmental conditions may affect neurocognitive development.
