Research Abstract |
The neural mechanism to detect locations of odors on antennae was investigated in American cockroaches. In sex pheromone-receptive glomeruli of males, topographic segregation of olfactory afferents based on their peripheral soma locations in the antenna is progressively more prominent towards later larval stages. Intracellular recording and stainings revealed that several pheromone-sensitive projection neurons had local receptive fields along the antenna. In contrast, the neural substrate to detect pheromone locations was poorly developed in the pheromone emitter, females.
