Emerging perception: Tracking the process of visual object recognition

    My studies using gaze behavior and V1 activity showed that, as part of the object recognition process, object features are prioritized over other parts of a scene. Such prioritization can be deduced from changes in eye movement behavior, as well as from the selective enhancement and suppression of V1 activity during the transition from initial viewing to the recognition of an object. Moreover, I found that changes in perception are accompanied by activity in cortical attention circuits, and that early and later sensory areas modulate their exchange of information during object recognition. From this, I conclude that visual object recognition does not occur at once and in a single cortical area, but is a constructive and distributed cortical process.
