From: Neurovascular coupling: in vivo optical techniques for functional brain imaging
An overview of the complete neurovascular model which assumes that the optical signals directly correspond to changes in the CMRO 2 . Normally neural activity is accompanying by changes in the local oxygenation. The relationship between neural activity, oxygen metabolism, and hemodynamic can be studied by variable imaging techniques (including VSDi, LSCI, fPAM, TPLSM and fNIR) in combination with local field potential recordings.
