Abstract: The tectofugal pathway is one of mainly visual pathways, it is composed of retine, tecta, necleus rotundus and ectost riatum. Among these structures exist topographic projections. Neurons, in the pathways, have dif ferent characteristics of receptive fields and reponse models to different stimulation. These structures may be more concerned with the analysis of directionality, orientation and velocity of moving objects, and the processing of colors, contours, figure/grpimd segregation, visually guided orientation, prey-catching and avoidance responses etc. The tectofugal pathway seems remarkably well-adapted to process specific visual information about object motion while ignoring most classes of self-induced visual motion.

Key words: avian, the tectofugal pathway, structures, functions
