# Brainμ: unified neuroscience foundation model decodes EEG, calcium imaging, neural probes

> Chinese research institute BAAI has released Brainmu 1.0, which it describes as the first foundation model to unify very different kinds of brain signals, EEG readings, calcium imaging and direct neural-probe recordings, inside a single encoding framework. Historically each of these modalities has been analyzed with its own specialized tools, which makes it hard to compare findings or build on them. Brainmu's aim is to treat them as one shared language. The model already underpins recent neuroscience work, including a Science study from June 2026 showing that memory reactivation can regulate sleep in both directions, with positive memories improving sleep quality and negative ones deepening fragmentation. The team frames that as a step toward treatments for depression and anxiety-related sleep disorders. The broader significance is methodological. Foundation models have reshaped language and vision by learning general representations from messy data, and applying the same recipe to neuroscience could let researchers pool decades of incompatible recordings into something a model can actually learn from.
