It has previously been assumed that once the lateral motor columns are set aside as a definitive region of the spinal cord in Rana p i p i e n s larvae (about stage V of Taylor and Kollros, '46), no further movement of cells into the column occurs. Since the cells of the lateral motor column (LMC) a
Counts of differentiating motor cells over the length of the brachial lateral motor column (LMC) indicate that a large decrease in cell number takes place during the larval period. During the same period an increase in nuclear size of the motor cells occurs with a maximum size attained just followin
## Abstract Neuronal turnover has been demonstrated during the period of differentiation and maturation of motor neurons in the developing lateral motor columns of __Rana pipiens__ larvae. As determined by thymidineβ^3^H labeling, cells continued to migrate into the lateral motor column (LMC) while
