BrainJanus: A Unified Model for Understanding and Generation across Brain, Vision, and Language

arXiv:2606.30319v1 Announce Type: cross Abstract: Modeling the bidirectional correspondence between external sensory stimuli and internal neural activity has emerged as a critical frontier in neuroscience. However, existing approaches predominantly treat brain encoding and decoding as isolated tasks, relying heavily on unimodal alignment and external priors while overlooking the brain's intrinsic nature as a multimodal integration system. To address these limitations, we propose BrainJanus, the first unified brain model that integrates brain, vision, and language within a single framework. Spe

Why this matters
Why now

Advances in multimodal AI and neuroscience are converging, enabling more sophisticated models to bridge the gap between brain activity and external stimuli.

Why it’s important

This development represents a significant step towards understanding complex brain functions and could accelerate progress in AI and human-computer interaction, impacting various industries.

What changes

The unified approach of BrainJanus moves beyond isolated encoding and decoding, suggesting a more integrated understanding of brain-computer interfaces and AI architectures.
