Near Infrared Spectroscopy alike Magnetic Resonance Imaging: Complementary Data in Rat Brain after Cocaine Treatment

Magnetic Resonance Imaging (MRI) and Near Infrared Spectroscopy (NIRS) are two major in vivo non invasive methodologies more and more applied in research. The first more than the second is largely used also in clinical domain. Both techniques are more or less related to the effectiveness of oxygen levels and/or functionality in blood and this can be exploited to monitor the influence of various factors and conditions upon the living tissue, in particular the brain.
