EyeBrain: Left and Right Brain Lateralization Activity Classification Through Pupil Diameter and Fixation Duration
Ko Watanabe, Pooja Pol, Nicolas Gro{\ss}mann, Shoya Ishimaru, Andreas Dengel

Abstract: The relationship between brain lateralization and cognitive functions is well-documented. The left hemisphere primarily handles tasks such as language and arithmetic, while the right hemisphere is involved in creative activities like drawing and music perception. Eye-tracking technology has shown the potential to reveal cognitive states by measuring ocular metrics such as pupil diameter and fixation duration. However, the ability to distinguish lateralized brain activity using these ocular metrics remains underexplored. Here, we demonstrate that pupil diameter and fixation duration can effectively classify left and right brain hemisphere activities. We obtained a considerably high classification performance, with an F1 score of 0.894. The results suggest that ocular metrics are robust indicators of lateralized brain activity and can be applied in cognitive monitoring and neurorehabilitation. Our future work expands on this by integrating these methods into real-time applications EyeBrain, potentially broadening their use across various cognitive and neurological domains.

Triple Configuration of Brain Networks Based on Recurrent Neural Networks: The Synergistic Effects of Exogenous Stimuli, Task Demands, and Spontaneous Activity

Abstract: The foundation of cognitive flexibility and higher-order intelligence lies in the functional structure and activity of brain networks, which can be dynamically configured by both external environments and internal states. However, decoding these dynamics from high-dimensional neural data remains a challenge. In this study, we propose a computational framework using Recurrent Neural Networks (RNNs) with neural dynamic constraints to model source-localized resting-state EEG data from $114$ participants. We aim to clarify the "triple brain network configurations" driven by exogenous and endogenous factors, including external stimuli, information processing tasks, and spontaneous activities. Our model identifies the parietal network as a critical hub supporting these multiple configuration patterns. Furthermore, we reveal that the anterior and posterior parietal regions exhibit distinct functional specializations under different stimulus modalities. By formalizing a triple configuration framework, this work separates latent factors of brain dynamics and underscores the computational significance of parietal regions in orchestrating higher-order intelligence.

Abstract: Non-invasive electrophysiology lacks methods that accurately reconstruct whole-brain spatiotemporal dynamics while incorporating individual cortical geometry, leaving current electroencephalography and magnetoencephalography source imaging limited by simplistic or biologically implausible priors. Here, we show that embedding participant-specific Geometric Basis Functions (GBFs), eigenmodes derived from each individual's cortical surface, provides a powerful anatomic constraint that resolves the inverse problem and improves reconstruction fidelity. The method reconstructs neural sources as linear combinations of geometric basis functions, thereby aligning source estimates with the geometric organization of neural dynamics. We validate GBF across the Meta-Source Benchmark, task-evoked data, resting-state networks, intracranial stimulation, and epilepsy data. The results demonstrate that GBF yields high localization accuracy and captures fast spatiotemporal dynamics consistent with anatomical pathways. These findings suggest that both spontaneous and evoked whole-brain activity can be described by hundreds of geometric modes, providing a compact yet accurate representation of neural sources. By linking cortical geometry to electrophysiological dynamics, GBF offers a versatile source imaging tool for both scientific and clinical applications.

It can simulate complete complex interactions. And it can do all that in the privacy of your own head, with no extra energy cost. And it can give you a deeper understanding of yourself.
You don't need chatbots for that. You don't need to lean on their nazi owners. You don't need to pay for them, you don't need to share the intimate details of your life, you don't need to burn the planet in the process.

Tiny plastic particles may be quietly threatening brain health.

Scientists estimate adults may consume about 250 grams of these particles each year, and some can accumulate in organs including the brain.

Abstract: Large-scale neuroscience is generating rich datasets across animals, brain areas and behavioral contexts, yet our modeling efforts remains fragmented across isolated experiments. We argue that understanding behavior requires integrative neurocybernetic models: understandable dynamical models that capture the closed-loop coupling of brain, body and environment, treat the brain as a controller pursuing latent objectives, represent structured variation across scales, and scale to heterogeneous datasets. Such models shift the goal from predicting neural recordings in isolation to inferring the organizing principles that govern neural and behavioral dynamics. We outline a practical route toward this goal by combining nonlinear state-space models and meta-dynamical extensions with scalable inference, knowledge distillation, mixed open- and closed-loop training, and connectomics-informed architectures. By pooling complementary constraints from recordings, behavior, perturbations and anatomy, integrative neurocybernetic models can provide statistical amplification, few-shot generalization, and mechanistic insight into shared dynamical structure, individual variation, and the control objectives that govern behavior. This agenda offers a model-centric path from fragmented data to a mechanistic science of how brains produce behavior.

One of those things about claims of “AGI” is that to really build a human-like intelligence we’d have to simulate a human brain as whole because 1. it’s the only thing we know that produces human intelligence and 2. no one knows how it actually works.
Because of (2) it’s irrelevant what anyone says about LLMs or any other technology (with the exception of simulating a whole brain)—you can’t know if a technology is intelligent like a human because we don’t know what that means or how that works.
Fun thing, it turns out it’s impossible to simulate a whole brain with the resolution required (basically quantum physics level), and you’d have to emulate a chemical and physical environment for the brain as well (it will also need a body etc.).
You’d also have to simulate other humans with brains from which the brain can learn; but to simulate those you’d have simulate evolving humans from single-cell organisms first etc etc ad infinitum

Playing Terra Nil right now, and it's funny because from the promo stuff I thought I wouldn't like it much, yet I'm enjoying myself a lot. There's definitely a game design lesson to be leaned here.
I was absolutely correct in my assessment that the game feels like it's actively trying to make suspension of disbelief as hard as possible with its completely ridiculous mechanics that make absolutely zero sense. "That's... Not how that works at all!" Is basically playing on repeat in my brain.
Furthermore, the entire technosolutionist tenor of the game rubs me very much the wrong way. This compounds with the physics- and biology-defying (or perhaps -spiting) fictional layer in cases like the convenient magical radiation-absorbing buildings so that you can reverse radiation contamination with a few simple clicks to be extremely bad politics actually...
But... The mechanics do work together quite well to make interesting puzzles with good gameplay that includes satisfying variety and challenges. The art is wonderful, and the music and audio design are spot on. The the result of each level is immensely satisfying, and the pacing is excellent.
I guess the lesson I'm taking away from this is that really solid fundamentals can triumph over an absolute cacophony of ludonarrative dissonance. That doesn't mean that in every decision between ludonarrative harmony (or just straight up believability) and neat mechanics you should compromise towards mechanics, but it reinforces the idea that if you make the mechanics enjoyable in the abstract, players (or at least, players like me) will be willing to compromise a *lot* on whether it actually makes any sense for things to work that way.
I'm still bothered by the "use technology to fix everything" politics, which prevents this game from being one I'll enthusiastically recommend, but despite myself I am having a lot of fun with it.

Abstract: Functional connectivity varies across individuals due to genetic and environmental factors, yet classical twin models typically confound non-shared environment with measurement error and are largely limited to resting-state analyses. We hypothesized that: i) explicitly modeling measurement error from repeated fMRI sessions enables more accurate application of classical twin models (ACE/ADE) to functional connectivity; ii) model applicability depends on scan-length and parcellation granularity; iii) genetic and environmental effects on functional connectomes show differentiated functional modules across conditions. We extended ACE/ADE models to include a repeated-scan derived error term by analyzing monozygotic and dizygotic twins from the Young-Adult Human Connectome Project dataset. Genetic and environment variance components were estimated for all functional couplings across resting-state and task conditions, integrated across conditions using a minimum-error criterion, and analyzed using multilayer community detection across resolution scales. Functional couplings segregated into distinct categories characterized by shared environmental, additive, dominant, or epistatic influences, with a substantial fraction not meeting twin-model assumptions. Integrating across conditions revealed hierarchical community structure in genetic and environmental components observed across community resolution scales. Incorporating measurement error into twin models improves interpretability and applicability at the functional connectome level, revealing that genetic and environmental influences are structured into coherent, multiscale brain networks.
