Branchiomotor activities in mouse embryo.

Abstract excerpt

Using a novel isolated hindbrain in vitro preparation, we demonstrate that, in the mouse, branchiomotor activities from trigeminal, facial, glossopharyngeal and vagal nerves start during segmentation, a crucial and conserved period of hindbrain embryogenesis. At embryonic day (E) 10.5, branchiomotor nerves are independently active in bursts, become coactive at a low frequency (about 0.5 min-1) at E12.5, before...
