This paper introduces SLIM-Brain, a novel foundation model for fMRI analysis designed to address the data and training inefficiency challenges of existing methods. It achieves state-of-the-art performance on various benchmarks while significantly reducing computational requirements and memory usage compared to traditional voxel-level approaches. The two-stage adaptive design, incorporating a temporal extractor and a 4D hierarchical encoder, is key to its efficiency.
