Abstract:

Recordings of several directionally selective motion detectors were made in the optic lobe. Object wavelength and velocity relationships were determined and compared with optomotor response and it was concluded these neurons were part of the neural system underlying flight control. Spectral sensitivity measurements were then made on these units to determine how the system is organized to distinguish color. It was found that these units receive information from all described photopigments but do not distinguish color. Hence, the color channel and movement channel are separate which is surprising in the context of economy of neuron and in knowledge of neuroanatomy. Two papers have been published as a result of this research.
