机译：Pathfinding of peripheral neurons in the central nervous system of an embryonic grasshopper (Chorthippus biguttulus)
The peripheral leg nerves of grasshoppers are initially formed by a set of pioneer neurons and guidepost cells. These cells are used as guiding structures for later-arising axons of sensory neurons. The development of the central projections of the pioneer cells, the guidepost cells and some sensory cells is shown with Lucifer Yellow injection or with DiI application. The axons of the pioneer cells Ti1 enter the central nervous system at 38 of embryonic development. They turn anteriorly close to the midline and ascend with no major branching to the brain. The axons of the guidepost cells Fe1 and Tr1 follow the same path but do not ascend to the brain. Sensory axons of the subgenual organ and the femoral organ probably do not follow the central path pioneered by the former neurons. They end ipsilaterally in the respective thoracic neuromere, as is found in the adult.
