Figure 19.4 Migration of neuronal precursors in the rostral migratory stream (RMS).
Brain slices from the forebrain, including the olfactory bulb, from a postnatal day 9 mouse
were labelled with small DiI crystals and migration was visualized by time-lapse
microscopy. Images are shown depicting unidirectional migration of neural precursors
from the anterior part of the subventricular zone (right side of panel) to the centre of the
olfactory bulb (left side of panel). The arrows indicate a single, long, leading process. Scale
