Multi-Channel, Light Reflectance Spectroscopy for Fast Detection of Hemodynamic Changes on the Spinal Cord and the Brain Induced by Electrical Stimulations in Rats

Multi-channel, light reflectance spectroscopy with thin needle probes is developed for fast detection of neuro-hemodynamic changes induced by electrical stimulations in rats, revealing hemo-neuro pathways and information processing between the spinal cord and the brain.
