Reliability of fNIRS for noninvasive monitoring of brain function and emotion in sheep

Abstract The aim of this work was to critically assess if functional near infrared spectroscopy (fNIRS) can be profitably used as a tool for noninvasive recording of brain functions and emotions in sheep. We considered an experimental design including advances in instrumentation (customized wireless...
