arXiv:2604.16370v2 Announce Type: replace Abstract: Decoding natural language from non-invasive electroencephalography (EEG) remains constrained by low signal-to-noise ratio and limited information bandwidth. This raises a central question: can sentence-level language be reliably recovered from such signals? Under realistic information constraints, this direct-recovery assumption may be too strong. We introduce a semantic compression hypothesis: non-invasive EEG may preserve recoverable semantic anchors rather than the full lexical--syntactic form of a sentence. From this perspective, direct s
Advances in AI, particularly large language models and neural decoding techniques, are enabling new breakthroughs in interpreting complex biological signals like EEG for language. This specific paper introduces a novel hypothesis for how to approach this decoding under current technological constraints.
This research suggests a more plausible pathway for decoding language directly from brain signals, focusing on semantic anchors rather than full linguistic reconstruction, which could accelerate brain-computer interface development. It significantly impacts the understanding of how language is represented and extracted from the brain non-invasively.
The focus in EEG-to-text decoding shifts from attempting direct lexical-syntactic reconstruction to a more achievable goal of semantic compression and recovery. This redefines the technical approach and expectations for non-invasive brain-computer interfaces (BCIs).
