Decrease in the number of facial motor neurons after axotomy in trkB (−/−) mice. A–F,Cresyl violet-stained sections show the reduction in the size of the axotomized facial motor nucleus (B) but the normal appearance of the surviving motor neurons (E) in P10trkB (−/−) mice. A, C, D, Wild-type mice. B, E, F, trkB (−/−) mice. G, H,Acetylcholinesterase activity in P7 wild-type (G) andtrkB (−/−) (H) mice. Similar activity was observed in the trkB (−/−) mutant mice when compared with wild-type mice. Magnification: A, B, G, H, 2.5×; C–F, 100×.
