It remains largely unclear why its electrical or magnetic stimulation can alleviate therapy-resistant chronic pain—albeit unreliably.

by Stony Brook University Whole-cell recordings of excitatory neurons in forelimb M1 were localized to L2/3 and L5. A, Schematic showing the anterior–posterior span of recorded slices, restricted to the forelimb area of M1. B, Recorded neurons were visualized with streptavidin labeling of biocytin and confirmed as excitatory by negative immunoreactivity for GAD67. GAD67 and merged...
