In the cortex, neurons that respond to specific orientations are organized into orientation columns. This raises the question: Are the orientation signals in the iso-orientation columns associated with cardinal orientations the same as those in the iso-orientation columns associated with oblique orientations, and is this signal influenced by experience? To explore this, iso-orientation columns in visual area 18 were examined using optical imaging techniques. Kittens were raised under either standard or modified conditions, including total darkness or rhythmic light stimulation through one or both eyes, which could potentially disrupt the orientation tuning of visual neurons. A signal profile around the pinwheel center was calculated to assess the distribution of the orientation signal within the hypercolumn. This profile exhibits a sinusoidal pattern with identifiable minima and maxima. To emphasize that these amplitude variations are localized within a specific circle rather than throughout the entire optical map, we used the terms “local minima” and “local maxima.” The number of local maxima in areas corresponding to oblique orientations was similar to those in regions associated with vertical orientations. The highest number of local maxima was found in horizontal iso-orientation columns, indicating a “horizontal bias.” This finding may be related to the postnatal development of sensory–sensory and sensory–motor integrations involving the visual system.

In this paper, we propose a deep learning denoising model based on long short-term memory (LSTM)-autoencoder (viz., LSTM-AE) to reduce motion artifacts. By training a neural network to reconstruct hemodynamic response coupled with neuronal activity, LSTM-AE achieves positive denoising results on both our synthesized noisy simulated dataset and the real dataset. The LSTM-AE processes the raw fNIRS in three phases: (1) Morphological feature extraction of the raw fNIRS is conducted through the encoder module. (2) The LSTM module captures temporal correlations between individual samples to enhance features. (3) The decoder module recovers and reconstructs the morphological feature information of fNIRS from the latent space. Finally, clean reconstructed fNIRS is generated at the output layer. We compare our proposed method with existing calibration algorithms for hemodynamic response estimation using the following metrics: mean square error (MSE), Pearson's correlation (<i>R</i><sup>2</sup>), signal-to-noise ratio (SNR), and percent deviation ratio (PDR). The proposed LSTM-AE method outperforms conventional methods, demonstrating an improvement in all these metrics. Additionally, the proposed LSTM-AE method shows statistically significant differences from other motion artifact algorithms in terms of effectiveness (<i>p</i> < 0.01, significance level α = 0.05).

This study investigates the effect of nonspecific visual stimuli with varying perceptual–cognitive constraints on jump performance, including countermovement jump height, reactive strength index modified, action time, and reaction time. A total of 299 soccer players were randomly assigned to four groups to assess the impact of different perceptual–cognitive tasks on countermovement jump performance. The results showed a significant reduction in jump height in all groups, with the most pronounced effect in the divided/attention simple reaction time task group (Δ height = −4.74 cm; <i>p</i> < 0.001). Action time was significantly shorter in all experimental jumps compared with controls (<i>p</i> < 0.001), and the reactive strength index modified increased across perceptual–cognitive tasks (<i>p</i> < 0.001) except in the divided/attention simple reaction time (<i>p</i> = 0.593). Reaction time increased in all groups, with the highest in the complex elective reaction time task (487.32 ± 153.75 ms; <i>p</i> < 0.001).

Despite being a widespread phenomenon across cultures, the nature and neural underpinnings of beat perception remain largely unknown. In the last decade, there has been a growing interest in developing methods to probe these processes, particularly to measure the extent to which beat-related information is contained in behavioral and neural responses. Here, we propose a theoretical framework and practical implementation of an analytic approach to capture beat-related periodicity in empirical signals using frequency-tagging. We highlight its sensitivity in measuring the extent to which the periodicity of a perceived beat is represented in a range of continuous time-varying signals with minimal assumptions. We also discuss a limitation of this approach with respect to its specificity when restricted to measuring beat-related periodicity only from the magnitude spectrum of a signal and introduce a novel extension of the approach based on autocorrelation to overcome this issue. We test the new autocorrelation-based method using simulated signals and by re-analyzing previously published data and show how it can be used to process measurements of brain activity as captured with surface EEG in adults and infants in response to rhythmic inputs. Taken together, the theoretical framework and related methodological advances confirm and elaborate the frequency-tagging approach as a promising window into the processes underlying beat perception and, more generally, temporally coordinated behaviors.</p>","PeriodicalId":11993,"journal":{"name":"European Journal of Neuroscience","volume":"61 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11760665/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143032891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we ask whether predictable distractors are able to reduce uncertainty in updating the internal predictive model. We show that utilising a predictable distractor identity is not fully automatic but in part depends on available resources. In an auditory spatial n-back task, listeners (<i>n</i> = 33) attended to spoken numbers presented to one ear and detected repeating items. Distracting numbers presented to the other ear either followed a predictable (i.e., repetitive) sequence or were unpredictable. We used electroencephalography (EEG) to uncover neural responses to predictable versus unpredictable auditory distractors, as well as their dependence on perceptual and cognitive load. Neurally, pairs of targets and unpredictable distractors induced a sign-reversed lateralisation of pre-stimulus alpha oscillations (~10 Hz) and larger amplitude of the stimulus-evoked P2 event-related potential component. Under low versus high memory load, distractor predictability increased the magnitude of the frontal negativity component. Behaviourally, predictable distractors under low task demands (i.e., good signal-to-noise ratio and low memory load) made participants adopt a less biased response strategy. We conclude that predictable distractors decrease uncertainty and reduce the need for updating the internal predictive model. In turn, unpredictable distractors might mislead proactive spatial attention orientation, elicit larger neural responses and put higher demand on memory.</p>","PeriodicalId":11993,"journal":{"name":"European Journal of Neuroscience","volume":"61 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11760630/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143032893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their importance, the neural mechanisms underlying word problem solving, especially in children, remain poorly understood. Here, we examine children's cognitive and brain response profiles for arithmetic word problems (AWPs), which involve one-step mathematical operations, and compare them with nonarithmetic word problems (NWPs), structured as parallel narratives without numerical operations. Behavioural results suggested that AWP performance was associated with both reading comprehension and arithmetic fluency, whereas NWP performance correlated only with reading comprehension. Neuroimaging results revealed distinct neural substrates: AWP solving primarily activated the anterior insula, middle frontal gyrus and intraparietal sulcus, whereas NWP solving engaged in the inferior frontal gyrus, middle temporal gyrus and angular gyrus. Critically, we observed a developmental shift: Children showed heightened prefrontal activation during AWP solving, contrasting with increased posterior parietal engagement in adults. Moreover, although adults demonstrated brain–behaviour associations, with slower AWP solving linked to stronger parietal activation, this relationship was absent in children. Taken together, these findings suggest that AWP solving recruits specialized arithmetic brain circuits that undergo a frontal-to-parietal trajectory. Our study thus provides a neurological basis for AWP solving in children, emphasizing the crucial role of the fronto-insular-parietal network.

The mechanism behind migraine chronification is poorly known and difficult to explore as CM has the same spectrum of pathogenesis as EM and the EM-CM transition is bidirectional. Central sensitization (CS) is a key phenomenon in migraine: its mechanisms include disturbed neural plasticity, which is the ability of the nervous system to adapt to endo- and exogenous changes. Cutaneous allodynia, a maker of central sensitization, may be an easy-to-determine marker of the EM-CM transition. Pituitary adenylate cyclase-activating peptide, a pro-inflammatory, vasodilatory and pain-producing neuropeptide, which has been proposed as an alternative to CGRP target in migraine, was shown to improve CS by regulating synaptic plasticity in the trigeminal nucleus caudalis in CM rats. Oxytocin and its receptor were found to influence CS through modulating synaptic plasticity in CM mice. Similar results were obtained for ephrin type-B receptor and its ligands. These and other studies suggest that neural plasticity may be important in CM pathogenesis. Still, its involvement in migraine chronification requires further studies which should include patients/animals with EM and CM. In this narrative/hypothesis paper, we review the current literature on the molecular mechanisms of CM pathogenesis and try to link them with neural plasticity and central sensitization to support the hypothesis that it is a key element in migraine chronification.</p>\u0000 </div>","PeriodicalId":11993,"journal":{"name":"European Journal of Neuroscience","volume":"61 2","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143032892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
