This paper will review the newest results and directions for the usage of optical coherence tomography as an imaging tool for brain studies, focusing mostly on a rodent model. Together with state of the art in the field, based on some of the most recent work, this paper will include a brief look on some results obtained by our group. Brain injuries and stroke data obtained by optical coherence tomography analyzing will be presented as a possibility of detection and evaluation for affected tissue, using this imaging system.
