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
https://arxiv.org/abs/2604.23562 https://arxiv.org/pdf/2604.23562 https://arxiv.org/html/2604.23562
arXiv:2604.23562v1 Announce Type: new
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.

I had a weird dream where I was talking to someone at some kind of ceremony, I think a funeral, where I had timidly painted my face with clay as part of some ritual. This person was talking about how far society has come while our brains have not caught up.
Imagine if your ancient cave dwelling ancestors were dropped into this world of cars, office hours, budgets, climate change, and AI. They would be absolutely freaking out and struggling to understand things all the time... Just like you are now.
Society teaches us to suppress these emotions. You're supposed to be OK with giant metal boxes flying around you in rumbling stampedes, but you feel it in unexplained anxiety. You're supposed to just fit your life into tight little bounds that ignore weather and season, but you feel it in more unexplained anxiety and depression. We are all part of something so big and complicated we can't make sense of it, we cannot possibly comprehend it all, it is simply too much to fully grasp the implications of our individual actions within global capitalism. Should we be surprised by our urge to simply destroy it, by the anger and desire to simply "smash" something far more complex than can be met with simple violence?
Some part of my brain was trying to remind me to be compassionate to myself. Perhaps that reminder can be useful to you as well.

Triple Configuration of Brain Networks Based on Recurrent Neural Networks: The Synergistic Effects of Exogenous Stimuli, Task Demands, and Spontaneous Activity
Binghao Yang, Guangzong Chen
https://arxiv.org/abs/2604.23525 https://arxiv.org/pdf/2604.23525 https://arxiv.org/html/2604.23525
arXiv:2604.23525v1 Announce Type: new
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.

arXiv:2604.25592v1 Announce Type: new
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.
