Definition
The rostral migratory stream (RMS) is a pathway along which developing neurons travel from the subventricular zone (SVZ) of the brain to the olfactory bulb. This a relatively long trip (several milimeters) for a cell measuring only 10-30 μm long. Once these cells reach the olfactory bulb they develop into interneurons. This pathway was originally found in rat brains but it has recently been discovered to exist in much larger brains including those of primates.
