Spatially Masked Regression Reveals Local and Distributed Predictability in Electrophysiological Recordings
Researchers have developed a new framework called Spatially Masked Regression (SMR) to analyze neural recordings. SMR quantifies how much of an electrode's signal reflects local activity versus distributed network activity. By progressively masking nearby electrodes, the method reveals that individual channels contain both local and broader distributed information, with significant predictability remaining even when immediate neighbors are excluded.
