This paper improves the Huth encoding pipeline for fMRI decoding and introduces fMRIFlamingo, a direct fMRI-to-text framework using Llama 3.2, but finds that decoding success is driven by the language prior rather than neural input.
This paper introduces a multi-feature fusion framework for semantic reconstruction from non-invasive brain recordings, combining static lexical (Word2Vec) and dynamic contextual (GPT) representations via cross-attention, achieving state-of-the-art performance in brain-to-text decoding.
Brain2Qwerty is a non-invasive brain-computer interface that decodes brain waves into text, enabling communication without surgery.
NeuroSonic introduces a conditional flow-matching framework for reconstructing continuous speech from EEG signals, addressing the structural mismatch between neural and acoustic data by learning a deterministic probability-flow velocity field. It achieves up to 26.3% improvement in perceptual quality over existing GAN, diffusion, and mean-flow baselines on cross-subject benchmarks.
This paper applies TopK Sparse Autoencoders to three EEG foundation models (SleepFM, REVE, LaBraM) to extract interpretable feature dictionaries and introduces a framework for concept steering, revealing representational failures and clinical entanglements.
Researchers propose Brain-CLIPLM, a two-stage EEG-to-text decoding framework using contrastive learning for semantic anchor extraction and a retrieval-grounded LLM with Chain-of-Thought reasoning, achieving 67.55% top-5 sentence retrieval accuracy and suggesting EEG-to-text decoding should focus on recovering compressed semantic content rather than full sentence reconstruction.
