This paper introduces Augmented Sparse Encoding Models to interpret brain responses to language using sparse features from language models, validated on high-field 7T fMRI data. It recovers known neural tuning properties and discovers a new voxel population tuned to people-related content.

Neuronal proteins from the brain drain to the dura, skull, and nose, whereas injected CSF-tracer accumulates in neck lymph nodes. The study highlights that the act of injection may perturb the system under investigation.
