ABSTRACT
Optical Brain Imaging is basically an imaging technique which uses light for understanding structures of our brain for various medical applications. Optical brain imaging methods within the last few years have showed tremendous revolutionary development. The current review is mainly focused on principles of novel brain imaging techniques. The methods included in this review are Intrinsic optical imaging, Diffuse Optical Tomography, Photoacoustic Microscopy, Diffuse Optical Tomography, Terahertz radiation, Near infrared microscopy, Voltage-sensitive dyes imaging, Ca2+ and other ion sensitive dye Imaging, Auto fluorescence and Metabolic related optical imaging and Optical coherence tomography. Some of these methods find their applications in clinical research and others in experimental neuroscience.
