This chapter examines some neural processes that a scene image undergoes as it moves through the visual system. It focuses on two opposite yet highly interactive neural systems, the frontoparietal network and the ventral visual stream. Visual recognition mechanisms in the ventral stream lean toward certain objects in visual scenes because they occupy a space that has already been allotted for a high priority by the lateral intraparietal area and the frontal eye fields. While the ventral visual system processes and determines the objects in that environment, the frontoparietal network allocates and points visual attention to important features of the environment.This division of labor by the two systems is supported by the view that spatial selection and target identification are separable parts of finding objects in visual scenes.

Keywords:   visual recognition, frontoparietal network, ventral visual stream, neural systems, target identification
