Contralateral motoneuron dendritic changes induced by transection of frog spinal nerves.
Changes in dendritic morphology were investigated following lesions of frog spinal nerves. Dendrite length, surface area, and volume, as well as measures of expansion and retraction were examined with the aid of a computer microscope system. We found that dendrites contralateral to the side of transection underwent a distal shift in their branching pattern without changing in total length or total number of branches.
