Structural organization of male-specific visual neurons in calliphorid optic lobes

摘要: The superiority of male flies over female in locating and intercepting small rapidly moving targets has been ascribed to differences their visual systems. In males, this sexual dimorphism is externally expressed by an area high acuity called the acute zone. Selective cobalt uptake reveals 12 types male-specific interneurons lobula, axons which terminate neuropil supplying premotor descending neurons neck flight motor circuits. dendritic fields individual can be extrapolated out into space demonstrate that each assigned a discrete panorama. 10 subtend areas retina associated with functional significance discussed respect putative receptive field model circuit for target location flies.
