Feedback-driven event-related potentials in conditional discrimination: insights from a matching-to-sample study
Frontiers in Human Neuroscience Score: 0.82 Published: 2026-02-20T00:00:00+00:00
Tags: EEG, ERP, methods, electrophysiology
Uses 64-channel EEG at 1024 Hz and event-related potentials (ERPs) during matching-to-sample; direct electrophysiology and neural time-series methods.
RSS summary
This study examined differences in event-related potentials (ERP) associated with the presentation of programmed consequences during conditional discrimination training in a matching-to-sample (MTS) paradigm. Electroencephalography (EEG) data were continuously recorded from n = 11 participants using a 64-channel wet-electrode system at a sampling frequency of 1,024 Hz. Three-phase MTS training and testing were customized using PsychoPy and featured 12 arbitrarily related abstract stimuli explici…
Temporal Coding rather than Circuit Wiring allows Hippocampal CA3 Neurons to Dynamically Distinguish Different Cortical Inputs

Dual-color optogenetic circuit mapping of MEC/LEC inputs to hippocampus and temporal coding; circuit-level electrophysiology and computational integration.
RSS summary
Memory relies on associating and indexing multimodal information. How does this occur within single neurons? The hippocampus integrates multisensory information from medial (MEC) and lateral (LEC) entorhinal cortices to form environmental representations1-6, yet their synaptic dynamics, circuit organization, and integrative functions remain elusive. Contrary to canonical models emphasizing anatomical and functional segregation, our dual-color optogenetic7 circuit mapping revealed that both MEC a…
Discovering macroscale functional organization on the structure of brain-like recurrent neural networks
bioRxiv Neuroscience Score: 0.75 Published: 2026-02-20T00:00:00+00:00
Tags: computational, methods, RNN, structure-function
Links structure to function in brain-like RNNs with parcellations and modules; computational neuroscience and interpretable brain models.
RSS summary
Understanding function from structure is a central topic in both neurobiology and artificial intelligence. In the human brain, macroscale functional organization, including functional parcellations, modules, and hierarchies, has been systematically linked to anatomical structure, providing an interpretable and clinically meaningful framework for linking structure to function. In contrast, although artificial neural networks are widely used as models of cognition, prior studies have not incorpora…
From Mary Shelley to Netflix: a Pan-European perspective on public communication of neuroscience and neurotechnology
Frontiers in Neuroscience Score: 0.72 Published: 2026-02-20T00:00:00+00:00
Tags: neurotechnology, communication, policy
Explicitly addresses public communication of neuroscience and neurotechnology; relevant for neurotechnology analyst context.
RSS summary
Scientific knowledge of the human brain has captivated the public’s attention and sparked their imagination for centuries. Comprehending the inner workings of the mind and the underlying molecular and physiological aspects of the central nervous system has long been the defining theme of contemporary Western scientific culture. Even as the focus has arguably shifted towards genomics in the early 21st century, the brain continues to hold the spotlight in science communication, perhaps bolstered b…
Conditioned Graph Reconstruction of Brain Functional Network Connectivity Reveals Interpretable Latent Axes of Sex and Fluid Intelligence
bioRxiv Neuroscience Score: 0.68 Published: 2026-02-20T00:00:00+00:00
Tags: methods, functional connectivity, computational
Generative framework for brain functional connectivity and network metrics with demographic/cognitive variables; methods for connectivity and interpretable encoding.
RSS summary
In studying the brain’s functional connectivity and its associations with clinically observed assessments, novel learning frameworks modeling its network properties in conjunction with assessment variables are crucial to uncover variable-specific patterns via meaningful encoding and reconstruction. We present a generative framework for modeling human brain functional connectivity features while retaining key network metrics and differences associated with demographic and cognitive variables. A c…
The parafascicular nucleus of the thalamus orchestrates coordinated skeletomotor, autonomic, and aversive state transitions
bioRxiv Neuroscience Score: 0.65 Published: 2026-02-20T00:00:00+00:00
Tags: optogenetics, circuits, methods
Optogenetics in mice with high-resolution continuous measures of skeletomotor and autonomic outputs; circuit-level neural manipulation.
RSS summary
The parafascicular nucleus (Pf), part of the intralaminar thalamic nuclei, has been implicated in diverse functions such as attention, nociception, and behavioral flexibility, yet its precise contributions to behavior remain poorly defined. In this study, we used optogenetics in male and female mice to study the role of Pf projection neurons using high-resolution and continuous measures to quantify both skeletomotor and autonomic behavioral outputs as well as motivational valence. We showed that…
A quantitative census of millions of postsynaptic structures in a large electron microscopy volume of mouse visual cortex
bioRxiv Neuroscience Score: 0.78 Published: 2026-02-20T00:00:00+00:00
Tags: methods, connectomics, EM, circuits
Dense EM connectomics and subcellular synaptic targeting methods; direct relevance to neural circuit and methods for large-scale neuroanatomy.
RSS summary
Neurons display a remarkable sub-cellular specificity in their synaptic targeting, which varies by cell type—for example, excitatory neurons prefer to target the spines of other excitatory cells. Modern dense neuroanatomy data, such as large volumetric electron microscopy connectomes, enable the study of this sub-cellular specificity and its context in a circuit at unprecedented scale and resolution. However, this scale has also made it challenging to create accurate and efficient methods for c…
Cholinergic—dopaminergic interplay underlies prediction error broadcasting
bioRxiv Neuroscience Score: 0.72 Published: 2026-02-20T00:00:00+00:00
Tags: computational, neuromodulation, reinforcement-learning
Neuromodulatory systems and coordinated encoding of prediction errors; core computational neuroscience and reinforcement learning.
RSS summary
Neuromodulatory systems, notably basal forebrain cholinergic and midbrain dopaminergic pathways, critically influence reinforcement learning (Schultz et al., 1997; Doya, 2002; Yu and Dayan, 2005). However, whether and how they cooperate or compete to jointly control associative learning functions remains unresolved. Here we demonstrate that basal forebrain cholinergic and midbrain dopaminergic projection systems form a coordinated and cross-regulating architecture for encoding prediction errors.…
Neural circuits regulating social dominance implement a strategy predicted by evolutionary game theory
bioRxiv Neuroscience Score: 0.65 Published: 2026-02-21T00:00:00+00:00
Tags: neural circuits, Drosophila, computational, behavior
Identifies neural circuit for decision to flee during fighting in Drosophila; circuit-level mechanisms and evolutionary game theory align with systems/computational neuroscience.
RSS summary
Social conflict is a fundamental challenge for all animals and determines access to critical resources like mates and food. Evolutionary game theory predicts that natural selection should yield competitive strategies that balance the benefits and costs of social conflict. However, whether such strategies are embedded within the neural circuits that regulate aggression remains unclear. Here, we identify a neural circuit regulating the decision to flee during fighting in male Drosophila and show t…
