In this paper, we reframe EEG explainability as a cross-modal generation task, shifting the paradigm from feature attribution to behavioral visualization. We introduce Facial Emoji Proxy Modeling, a novel framework that translates high-dimensional EEG signals into identity-anonymized facial emojis. Guided by the neuroscientific inspiration of neural-facial association, this approach grounds neural representations in the manifold of observable facial dynamics. Technically, our framework integrates FMENet, a specialized backbone modeling expression-relevant spatial synergies, and the Facial Emoji Learning Branch (FELB), which treats emoji reconstruction as a structured semantic regularizer. Extensive experiments on EAVand MMER benchmarks demonstrate that our method achieves state-of-the-art accuracy among EEG-only models. Crucially, it generates semantically faithful facial animations that provide a transparent, privacy-preserving window into the brain’s emotional evolution, effectively allowing users to “see the emotion” directly from neural signals.

While deep learning has pushed classification accuracy to impressive levels(Zhong et al., 2022 ; Altaheriet al., 2023 ; Lawhern et al., 2018 ; Ding et al., 2022 ; Eldeleet al., 2024), a profound dichotomy persists between model performance and human interpretability. In essence, prevailing models behave as inscrutable “black boxes”, mapping noisy, high-dimensional EEG sequences to discrete labels without offering an intelligible trace of how the emotional experience unfolds in the neural signal. This opacity fundamentally limits their deployment in high-stakes domains, such as clinical neurofeedback and trustworthy BCI, where verifiable understanding is as critical as prediction.  \nThe quest for interpretability has traditionally followed two paths. Post-hoc attribution methods (e.g., Grad-CAM) analyze trained models to highlight influential EEG channels or time points (Miao et al., 2025 ; Bouazizi & Ltifi, 2025 ; Vakala Rani et al., 2025) . However, these saliency maps remain abstract, pointing to where the model attends rather than explaining what it perceives. Alternatively, built-inneuroscientific constraints incorporate priors like spectral dynamics into network design (Zhang et al., 2021 ; Ning et al., 2023 ; Liu et al., 2024) . Yet, their explanations remain couched in domain-specific jargon (e.g.,“alpha-band power in frontal electrodes”), failing to bridge the “last mile” to externally observable behavioral semantics.  \nThe core bottleneck lies in the absence of a semantic bridge capable of translating internal neural dynamics into a intuitively understandable vocabulary. To address this, we propose a paradigm shift: moving from the question of“which features matter?”
