A glassmicroelectrode was inserted in to the neurons responding to movements of a spot in the lobula or lobula plate of the optic lobe of oriental fruit fly, Bactrocera dorsalis Hendel. Intracelluler recordings to moving spot were classified into two types: non-directional and directional types. Directional type was divided into the one directional and the two directional. For the non-directional and directional intemeurons were widely founded in the region of the lobula, it was assumed that the processing of the visual direction was conducted in the region of the medulla to the lobula, and that the neural integration is performed in the central part of the optic lobes, the lobula and the central pathway to the central brain.
