摘要

In this article, spectral domain optical coherence tomography is used to measure the hemodynamic response induced by optogenetic stimulation in the somatosensory cortex of transgenic mice. By analyzing the 3-D angiograms and Doppler measurements produced by coherence tomography, we observed significant increase in blood flow as a result of increased vessel diameter and blood velocity following optical stimulation of cortical neurons. Such distinct responses were not observed in control experiments where the brain of wild-type mice were exposed to the same light pulses.
