Representation of the body surface in the gracile, cuneate, and spinal trigeminal nuclei of the little red flying fox (Pteropus scapulatus).
The body surface representation in the gracile, cuneate, and spinal trigeminal nuclei of the little red flying fox (Pteropus scapulatus) was examined. As in other species, it was found that any single cross-section through all three nuclei contains a representation of most, or all, of the body surface. In the little red flying fox, however, this representation is arranged as a series of dorsolateral to ventromedially oriented bands, within which there are no apparent topographies. These bands are arranged in such a way that the spatial relationships between body regions in the representation do not reflect those at the periphery.
