Coarse-to-fine Hierarchical Architecture with Sequential Mamba for Brain Reconstruction
CHASMBrain uses dual-stream Mamba in a coarse-to-fine hierarchy to predict fMRI from images, reporting 0.429 Pearson correlation and 0.261 MSE on NSD with causal evidence that patch and CLS streams specialize to early versus higher visual cortex.
