Despite its extensive use, the central nervous system (CNS) effects of arecoline remain inadequately understood. This study aims to investigate the central actions of arecoline through a comprehensive, multi-dimensional approach that integrates behavioral assays, neuroimaging techniques, calcium signaling analysis, and transcriptomic profiling. Our findings demonstrate dose-dependent addictive properties of arecoline, alongside distinct behavioral alterations that highlight its potential for addiction. Neuroimaging and calcium signaling data revealed region-specific alterations in neural activity, particularly in areas associated with learning, memory, and reward processing. Furthermore, transcriptomic analysis identified significant changes in gene expression, particularly in pathways related to synaptic plasticity, calcium signaling, and metal ion transport. These results provide valuable insights into the addictive potential of arecoline and its underlying neurobiological mechanisms, offering crucial information for understanding its broader impact on CNS function. The study's findings hold significant implications for informing public health strategies aimed at addressing arecoline misuse and its potential role in addiction-related disorders.</p>","PeriodicalId":56016,"journal":{"name":"Frontiers in Integrative Neuroscience","volume":"19 ","pages":"1545260"},"PeriodicalIF":2.6,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12014716/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144013639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we employ a phenomenon of greater ERP amplitudes in PO4/8 electrodes associated with insightful problem solving. In this study, 114 high school students (aged 16-18) with varying degrees of general giftedness and mathematical expertise were asked to solve mathematical problem of three distinct type: (1) function problems, whose solutions are memory-based; (2) area problems that necessitate strategic thinking; and (3) insight problems, that necessitate insight for their resolution. The problem solving process was accompanied by ERP recording. We demonstrate that variations in accuracy of solutions and reaction time for correct responses between tasks are influenced by students' general giftedness and mathematical expertise.

These methods are based on leveraging neuroplasticity through the utilization of movement, not as \"exercise\" or externally imposed motor sequences, but as a means for effective, <i>two-way felt communication</i> with the recipient and their brain. Through <i>connecting with the recipient, starting where they are-motorically, emotionally, and cognitively</i>, we follow their <i>unique responses, moment-by-moment</i>, creating a dance-like dyadic process of self-discovery that mimics the spontaneous, organic way typically developing children play, learn, and grow. Practitioners in these methods, by joining and creating mutual connection with the recipient, help turn the subjective experience of the recipient into a reliable means of attaining spontaneous, mutually generated emergent learning in the recipient. In this process the autonomy of the recipient is respected and enhanced. Our work will be described through direct applications to autism seen as a neuro-motor-sensing disorder where those challenges can be transcended through the dyadic dance embodied in our techniques. Since 87% of children with autism spectrum disorder have significant movement challenges, we propose that movement, as a means for effective two-way communication with the child and their brain, needs to play a central role in autism intervention. In this article we outline how our interventions take place through case studies, vignettes and discussion, separately for each of the two methods. This article will also include recommendations for conducting investigations that characterize some of the basic components of these two methods, utilizing experimental designs and recently developed technologies and biometrics that generate unique individual profiles of both the receiver and the provider of the intervention, and of the interbrain synchrony, correlate them with changes in movement organization, cognitive functioning and coherence, and track changes in the signal-to-noise ratio. These methods should enable refinement and scalability of tracking and assessing the mechanisms and effectiveness of the interventions.</p>","PeriodicalId":56016,"journal":{"name":"Frontiers in Integrative Neuroscience","volume":"18 ","pages":"1489345"},"PeriodicalIF":2.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12031662/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144057490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By using data acquired on non-human primates as a reference, important progress in knowledge of the human brain and its functions has been achieved. The translational impact allowed by this scientific effort must be recognized in the implementation of the current surgical techniques particularly in support of the neurosurgical approach to brain tumors. In the surgical treatment of brain tumors, the ability to maximally extend the resection allows an improvement in overall survival, progression-free survival, and quality of life of patients. The main goal, and, at the same time, the main challenge, of oncological neurological surgery is to avoid permanent neurological deficit while reaching maximal resection, particularly when the tumor infiltrates the neural network subserving motor functions. Brain mapping techniques were developed using neurophysiological probes to identify the areas and tracts subserving sensorimotor function, ensuring their preservation during the resection. During the last 20 years, starting from the classical \"Penfield\" technique, brain mapping has been progressively implemented. Among the major advancements was the introduction of high-frequency direct electrical stimulation. Its refinement, along with the complementary use of low-frequency stimulation, allowed a further refinement of stimulation protocols. In this narrative review, we propose an analysis of the process through which the knowledge acquired through experiments on non-human primates influenced and changed the current approach to neurosurgical procedures. We then describe the main brain mapping techniques used in the resection of tumors located within sensorimotor circuits.

First we define the primitives of movement in relational terms, as in comparative anatomy, yielding homological primitives. Then we define modules, generative rules and the architectural plan of behavior in terms of these primitives. In this way we expose the homology of behaviors, and establish a rigorous trans-phyletic comparative discipline of the morphogenesis of movement-based behavior. In morphogenesis, behavior builds up and narrows incessantly according to strict geometric rules. The same rules apply in moment-to-moment behavior, in ontogenesis, and partly also in phylogenesis. We demonstrate these rules in development, in neurological recovery, with drugs (dopamine-stimulated striatal modulation), in stressful situations, in locomotor behavior, and partly also in human pathology. The buildup of movement culminates in free, undistracted, exuberant behavior. It is observed in play, in superior animals during agonistic interactions, and in humans in higher states of functioning.
