This article presents the concept of the neurotechnology shift , understood as a technoscientific, cognitive, and sociocultural transformation through which neurotechnologies progressively expand into daily life, turning the brain itself into a shared interface between biological cognition and digital systems. This condition may eventually give rise to neurotechnological natives , a concept that is introduced here as a heuristic hypothesis intended to guide interdisciplinary research. Rather than predicting the emergence of a homogeneous generation shaped by neurotechnologies, the concept functions as an analytical tool to structure inquiry into the implications of brain–technology interaction in everyday contexts. To this end, the article outlines a research agenda organized across three dimensions of the neurotechnology shift: technoscientific infrastructures enabling scalable brain–technology interaction and neurodata ecosystems; cognitive implications related to neural plasticity, identity, impulse control, and language processes; and sociocultural transformations concerning governance, inequality and access, and collective imaginaries. Understanding the dynamics and bidirectional interactions across these three dimensions is essential for anticipating the ethical, legal, and societal implications of the emerging brain‐as‐interface era.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"27 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Duchenne muscular dystrophy (DMD) is characterized by aberrant AMPK activation and disrupted metabolic signaling. This study investigates the expression and regulation of the LKB1–STRADα–MO25 heterotrimeric complex, the primary upstream activator of AMPK, in DMD models. We analyzed muscles from dystrophic mice (BL10 mdx and D2 mdx ) and patient‐derived cells and found significant downregulation of the LKB1 complex across all disease stages in the DMD models, a defect not observed in an amyotrophic lateral sclerosis model. Treatment with the broad‐spectrum HDAC inhibitor vorinostat effectively restored LKB1 expression at both transcript and protein levels in D2 mdx mice. This restoration was mechanistically linked to downregulation of miR‐451, miR‐195, and miR‐17, which function as post‐transcriptional repressors of LKB1. Conversely, the selective HDAC1/2 inhibitor Rodin‐A increased Lkb1 mRNA but failed to rescue protein levels or alter miRNA expression. Our data identify the axis LKB1–STRADα–MO25 as a critical regulatory node that is disrupted in DMD, but remains responsive to epigenetic modulation. These findings suggest that restoring LKB1 activity via HDAC inhibition or miRNA targeting may represent a therapeutic avenue to address dystrophic muscle dysfunction.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"31 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148767450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prior work suggested that bi‐hemispheric transcranial direct current stimulation (tDCS) paired with bimanual mirror‐movement training may transiently improve fine motor control in affected pianists. This case‐control pilot study tested whether extending this approach to three consecutive days would produce detectable and sustained benefit. Ten professional pianists with unilateral musician's dystonia and 10 matched healthy pianists received 30 min of bi‐hemispheric tDCS over sensorimotor cortices while performing bimanual mirrored finger exercises on three consecutive days, with follow‐up assessment 10 days later. After exclusions, analyses included eight patients and eight controls for Musical Instrument Digital Interface‐based motor outcomes and six patients and eight controls for video ratings. As anticipated, dystonia patients showed poorer temporal motor control and lower subjective performance ratings than controls. However, the protocol did not produce significant group‐level improvement in objective motor performance, expert‐rated movement impairment or regularity, or subjective performance, nor was benefit retained at 10 days. Video ratings of movement impairment showed acceptable reliability, whereas regularity ratings did not. These findings do not support detectable efficacy of this consecutive‐day protocol under the present conditions and highlight the need for larger randomized, sham‐controlled studies.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148767481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these challenges, this article presents MPC‐DETR with improved matching (DEIM), a real‐time gear defect detection model that achieves an optimal balance between accuracy and efficiency through multi‐order feature aggregation and dual‐domain optimization. The architecture employs a multi‐order gated aggregation backbone to capture minute defects within complex gear textures while maintaining computational efficiency. Subsequently, a depthwise frequency‐spatial convolution module decouples defect signals from background noise via spatial–frequency collaborative processing, capitalizing on the distinct spectral characteristics inherent to industrial interference. Building upon these refined features, an efficient multi‐scale fusion module leverages shared large‐kernel convolutions with dynamic kernel generation, enabling precise localization across heterogeneous defect scales. Extensive evaluations on a self‐constructed GEER‐DET dataset demonstrate that MPC‐DEIM attains 95.2% mean average precision (mAP)@0.5, surpassing the DEIM baseline by 5.1% while reducing computational costs by 56.6%, and comprehensively outperforming state‐of‐the‐art detection transformer (DETR)‐series and you‐only‐look‐once (YOLO)‐series algorithms. Validation on the public GSD dataset achieves 98.8% mAP@0.5 with a 5.5 percentage point improvement. Additional cross‐dataset evaluations on NEU‐DET, PCB‐DET, and MS COCO further confirm broad cross‐industry applicability.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"66 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148767480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how long‐term monocultural experience shapes this process remains unexplored. Using vMMR, a neural index of prediction‐error signaling, we found that predominantly monocultural Mainland Chinese exhibited a significant negative vMMR specifically to nondominant cultural deviants, while showing null responses to dominant cultural deviants. For Western participants, our primary analysis revealed no statistically significant vMMRs to both nondominant and dominant cultural deviants. Furthermore, exploratory regression analyses indicated that higher interdependent self‐construal predicted a more positive vMMR to nondominant cultural deviants across both groups, suggesting a potential general role for this social‐cognitive trait in modulating preattentive salience. No significant modulation effects were found for independent self‐construal.

This multicenter retrospective study developed an automated, multi‐sequence MRI‐based diagnostic model for early ONFH using data from 342 ONFH‐affected femoral heads (FHs) from 282 patients and 265 healthy FHs from 233 healthy individuals obtained from two geographically distinct institutions. The dataset comprised three MRI sequences (T1WI, FS‐T2WI, and Cor STIR) and 7844 annotated FH instances labeled as normal or abnormal. A You Only Look Once (YOLO) segmentation model was trained on both single‐sequence and multi‐sequence datasets, and a global attention mechanism (GAM) was integrated to enhance diagnostic performance, yielding the GAM‐YOLO model. Model performance was compared with that of radiology residents using Fisher's exact test. The multi‐sequence YOLO model achieved superior diagnostic accuracy (sensitivity 93.19%, specificity 94.65%, accuracy 94.04%) compared to single‐sequence models. Incorporation of GAM further improved performance (sensitivity 97.00%, specificity 97.52%, accuracy 97.30%; p < 0.05).

While rates of comorbidity are high, evidence has suggested there are important distinctions between neurodevelopmental phenotypes. To understand these distinctions, we evaluated whether proposed neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE) criteria in the appendix of the Diagnostic and Statistical Manual for Mental Disorders (Fifth Edition) can differentiate FASD from ADHD. We conducted systematic searches across three databases (Medline, PsycINFO, PubMed) to identify studies comparing behavioral and cognitive functioning between FASD, ADHD, and healthy controls (HCs). Outcomes indicated FASD individuals have greater magnitude neurodevelopmental deficits than ADHD; however, no differences were found regarding the pattern of deficit because of methodological limitations, such as low I2. Moreover, outcomes supported adaptive and neurocognitive (executive functioning) criteria but did not support self-regulation criteria. These findings collectively underscore a need for clinicians to consider the magnitude of deficits presented to facilitate accurate recognition of PAE. Further research characterizing ND-PAE criteria and differences in the magnitude of deficits between disorders may ultimately support more accurate differential diagnosis.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"1562 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/nyas.70343","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148767483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these dynamics are perceived quite differently: music as rhythmic, and speech as quasi‐rhythmic. Here, we aim to identify whether this distinction between rhythm and quasi‐rhythm is sourced from the raw acoustic waveform by analyzing the modulation spectrum of the acoustic envelope. We analyzed several large corpora on three scales: the coarsest scale containing recordings of each corpus, the intermediate scale of individual speakers/songs, and the finest scale of individual sentences or short musical segments. We confirm previous findings that speech and music modulation spectra differ in their center frequency, which reflects how quickly the sound envelope fluctuates, but find that the modulation bandwidth, which captures how periodic the speech/music envelope was, is comparable for music and speech. Furthermore, the bandwidth is largely preserved across the three scales, indicating that the corpus‐level temporal irregularity is dominated by the irregularity within a few seconds of speech/music recordings. These results demonstrate that the perceived rhythmicity of music may not directly reflect the temporal periodicity present in its acoustic structure.","PeriodicalId":8250,"journal":{"name":"Annals of the New York Academy of Sciences","volume":"36 1","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148767484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
