20-P005 Study of the development of the interpeduncular nucleus evidences multiple origins in the rostral hindbrain

ume changes were influencing cell movement. We also observed that the shape of the explant influenced the direction of cell migration. We propose that increased cell volume provides the driving impetus for the start of cell migration. The enlarged cells produce points of dislocations, which are determined by the physical constraints of the tissue, and that foreshadow and dictate the direction of cell movement.
