FUS neuromodulation in PD vs healthy mice shows disease-state matters: in unilateral PD, FUS inhibits GPe calcium for ~3 min with behavioral readout; peer-reviewed JNE, wearable FUS + fiber photometry. Direct relevance to non-invasive neuromodulation and clinical translation. tier-1
RSS summary
Objective. Focused ultrasound (FUS) neuromodulation holds strong potential for treating neurological disorders, but most preclinical studies have been performed in healthy animal models. How disease states influence the FUS neuromodulation effects remains poorly understood, limiting clinical translation. Approach. We used Parkinson’s disease (PD) as a model to compare the calcium and behavioral responses to FUS neuromodulation in healthy and diseased mice. The PD mouse model was the unilateral dopamine depletion model, induced by injecting 6-hydroxydopamine into the left middle forebrain bundle. FUS was targeted at the left external globus pallidus (GPe) in freely moving mice using a wearable device. Calcium activity in the GPe was monitored via fiber photometry, and motor behavior was assessed using video tracking. Main results. In unilateral PD mice, FUS significantly inhibited GPe calcium activity, and this inhibition lasted for ∼3 min after stimulation. This inhibition was accompan…

RSS summary
arXiv:2602.20932v1 Announce Type: cross Abstract: An electroencephalogram (EEG) records the spatially averaged electrical activity of neurons in the brain, measured from the human scalp. Prior studies have explored EEG-based classification of objects or concepts, often for passive viewing of briefly presented image or video stimuli, with limited classes. Because EEG exhibits a low signal-to-noise ratio, recognizing fine-grained representations across a large number of classes remains challenging; however, abstract-level object representations may exist. In this work, we investigate whether EEG captures object representations across multiple hierarchical levels, and propose episodic analysis, in which a Machine Learning (ML) model is evaluated across various, yet related, classification tasks (episodes). Unlike prior episodic EEG studies that rely on fixed or randomly sampled classes of equal cardinality, we adopt hierarchy-aware episode sampling using WordNet to generate episodes with …

RSS summary
arXiv:2602.17557v2 Announce Type: replace Abstract: Alzheimer’s disease (AD) and Lewy body dementia (LBD) present overlapping clinical features yet require distinct diagnostic strategies. While neuroimaging-based brain network analysis is promising, atlas-based representations may obscure individualized anatomy. Gyral folding-based networks using three-hinge gyri provide a biologically grounded alternative, but inter-individual variability in cortical folding results in inconsistent landmark correspondence and highly irregular network sizes, violating the fixed-topology and node-alignment assumptions of most existing graph learning methods, particularly in clinical datasets where pathological changes further amplify anatomical heterogeneity. We therefore propose a probability-invariant random-walk-based framework that classifies individualized gyral folding networks without explicit node alignment. Cortical similarity networks are built from local morphometric features and represented …

RSS summary
Visual false memory refers to our tendency to falsely recognize novel stimuli that are visually similar to seen stimuli. Visual false memory also occurs when stimuli are meaningful, suggesting that semantic information interferes with the encoding of visual details. However, the neural mechanisms of this semantic interference effect are largely unknown. In the present fMRI study, participants were scanned while encoding visually similar fonts presented with words (word-fonts) or pseudowords (pseudoword-fonts), and later, when recognizing old, new similar (lures), and new dissimilar (novel) fonts displayed in the same meaningless letter string. We performed (1) representational similarity analysis (RSA) at encoding to identify visual, visuosemantic, and semantic representations associated with subsequent visual true and false font recognition, (2) encoding-retrieval similarity (ERS) analysis to assess their reinstatement during retrieval, and (3) mediational analyses to examine hippocam…

arXiv:2510.22129v3 Announce Type: replace-cross Abstract: Understanding affect is central to anticipating human behavior, yet current egocentric vision benchmarks largely ignore the person’s emotional states that shape their decisions and actions. Existing tasks in egocentric perception focus on physical activities, hand-object interactions, and attention modeling - assuming neutral affect and uniform personality. This limits the ability of vision systems to capture key internal drivers of behavior. In this paper, we present egoEMOTION, the first dataset that couples egocentric visual and physiological signals with dense self-reports of emotion and personality across controlled and real-world scenarios.

RSS summary
Steady-state visually evoked potentials (SSVEP), owing to their high signal-to-noise ratio and low training cost, are widely regarded as an effective approach for constructing visually driven brain-computer interfaces (BCI), particularly in neurorehabilitation applications. However, the accommodation-vergence conflict (VAC) commonly present in mixed reality (MR) and virtual reality (VR) head-mounted displays may attenuate neural responses in the visual cortex, thereby compromising the long-term usability of such systems. This study aims to systematically evaluate the effects of MR and VR environments under different virtual depth conditions on SSVEP signal quality, classification performance, and visual comfort, providing parameter guidelines for the design of immersive visual BCIs in rehabilitation contexts.

Uses iEEG and RDMs to evaluate an RL model of face perception; bridges neural decoding and computational neuroscience. Takeaways: RL matches supervised/unsupervised for neural fit; iEEG validates model. Preprint. Tier-1.
RSS summary
Deep neural networks have shown high accuracy in modeling neural responses in the visual system, but most models rely on supervised learning, which requires training on ground-truth labels that are typically unavailable in real-world settings. While unsupervised models can address this limitation, they miss another key aspect: visual representations are shaped by feedback from the environment. We introduce a reinforcement learning (RL) model of face perception that incorporates both input stimuli and feedback from the environment. Inspired by human interactions, we train the model to approach faces yielding positive interactions and avoid faces yielding negative interactions. Using intracortical electroencephalography (iEEG) data and Representational Dissimilarity Matrices (RDMs), we evaluate the model’s ability to account for neural responses. Our RL model performs at the same level as supervised and unsupervised models, capturing neural responses to complex visual stimuli. The findin…

EEG alpha reactivity as biomarker for aging and dementia (AD vs LBD); methodology and cholinergic mechanisms. Supports EEG-based biomarkers and clinical neurophysiology, not BCI control.
RSS summary
Alpha reactivity—the attenuation of the alpha rhythms upon eye-opening—is a well-known phenomenon in electroencephalography (EEG). Altered alpha reactivity has increasingly been recognized as a potential biomarker for cognitive aging and various types of dementia. This mini-review synthesizes the existing literature on EEG alpha reactivity in older adults, highlighting its clinical implications and neurobiological underpinnings. Methodological issues in quantifying alpha reactivity are first addressed, including the choice of reactivity index, frequency bands, and spatial analysis methods. The review then summarizes evidence that alpha reactivity declines with healthy aging and is further reduced in dementia, especially Alzheimer’s disease (AD) and Lewy body dementia (LBD). Importantly, distinct patterns of reduced alpha reactivity may aid in differential diagnosis. It has been reported that AD is often characterized by reduced alpha rhythm during eyes-closed rest, whereas LBD typicall…

Editorial on naturalistic neuroscience and ethology: behavior and ecology matter beyond environment. Informs experimental design for neural decoding and future BCI studies.
RSS summary
Nature Neuroscience, Published online: 27 February 2026; doi:10.1038/s41593-026-02225-zAs neuroscience increasingly recognizes that understanding the brain requires studying natural behavior, it has begun to adopt more naturalistic experimental environments as a means to that end — an important and welcome shift. Yet environmental realism alone does not guarantee that natural behavior is being studied and, in some cases, can create the illusion of ecological relevance or even promote unnatural behavior if the behavioral context is poorly aligned with a species’ ecology. Keeping sight of our central goal — understanding how brains support the actions animals evolved to perform — requires an ethological focus not only on where experiments occur, but on what animals are actually doing and whether the environment affords those behaviors.
Dendritic Computation and the Fine Structure of Receptive Fields: A Model of V1 Neurons
bioRxiv Neuroscience Score: 0.52 Published: 2026-02-27T00:00:00+00:00
Tags: computational neuroscience, methods, tier-2
Computational model of V1 receptive fields from dendritic integration; no recording or BCI. Relevant to computational neuroscience and future interpretability of cortical signals. Preprint, tier-2.
RSS summary
Dendrites are now recognized as nonlinear integrative compartments that can implement complex computations within single neurons, yet their specific contribution to cortical response diversity remains incompletely understood. In primary visual cortex (V1), neurons exhibit a broad range of response properties, including simple, complex, and end-stopped selectivity, but the mechanisms by which such diverse receptive field structures arise within a largely homogeneous population of pyramidal cells are still debated. This work presents a computational model in which these response classes emerge from dendritic integration of spatially organized excitatory and inhibitory inputs. In the model, synaptic inputs are distributed across dendritic branches according to their orientation preference and location within an underlying orientation map, and dendritic nonlinearities transform these inputs into somatic responses. By varying the relative distributions of excitatory and inhibitory inputs al…

Neurorehabilitation needs a qualitative perspective: a case exemplar from stroke recovery and rehabilitation

Argues for qualitative methods alongside quantitative neurorehabilitation and mentions novel neurotechnologies; stroke/plasticity context. Tangential to BCI device or decoding; useful as translation/context. Tier-2.
RSS summary
Neurorehabilitation is a medical process using neuroplasticity to help people recover from nervous system damage (like stroke, injury or disease) by improving function, independence, and quality of life through therapies (physio, occupational, speech) to retrain the brain and learn new ways to perform daily tasks, addressing physical, cognitive, and emotional needs. This process is shaped by the dynamic interaction of the person, the environment, and the task. Quantitative methods rooted in the science of experience-dependent plasticity, and rigorous clinical trial designs have produced significant advances, including the development of novel neurotechnologies. However, the comprehensive translation of these advances into meaningful outcomes for people living with a neurological condition requires a broader perspective. Central to this perspective is the recognition that the recovery process, includes motor/physical, sensory/perceptual, cognitive, affective, and psychosocial dimensions…
