Summary

• What is new: Introduces UMBRAE, a unified approach for brain signal decoding, aligning instance-level conceptual and spatial details, and a cross-subject training strategy.
• Why this is important: Existing research struggles with retrieving accurate spatial information from brain signals and relies on subject-specific models.
• What the research proposes: UMBRAE utilizes a universal brain encoder for multimodal-brain alignment and a cross-subject training strategy to improve spatial detail recovery and adapt to new subjects with minimal data.
• Results: UMBRAE achieves superior performance on both new and established tasks, demonstrating its effectiveness in decoding brain signals.
