Mixed Signals: On Separating Brain Signal from Noise

Research output: Contribution to journalShort survey

14 Scopus citations


Accurate description of human brain function requires the separation of true neural signal from noise. Recent work examining spatial and temporal properties of whole-brain fMRI signals demonstrates how artifacts from a variety of sources can persist after rigorous processing, and highlights the lack of consensus on how to address this challenge.
