M4Raw Brain v1.6
M4Raw Brain is a multi-contrast, multi-repetition, four-channel k-space
dataset acquired on a 0.3-T whole-body MRI system. The release contains T1w,
T2w, FLAIR, and GRE brain acquisitions from healthy volunteers, including
explicit motion subsets and an expanded repeated-acquisition test cohort.
Companion dataset: M4Raw-Abdomen
is a separate low-field abdominal MRI k-space and segmentation dataset and
will be made public soon. Until then, the linked private… See the full description on the dataset page: https://huggingface.co/datasets/mylyu/M4Raw_brain.brain-lm-alignment-ds001894

CDL DevAI results — brain × interpretability × localisation, per model per checkpoint
Developmental analysis of 10 language-model families against the ds003604 auditory
language fMRI dataset. For every training checkpoint of every model we measured three
things and here report them side by side:
