Even at the stage of the retina, a division arises between the dorsal and the ventral stream. The dorsal stream is responsible for movements in relations to objects, and is unconscious. The ventral stream has specialised modules for different aspects of vision. This processing happens at a still unconscious stage, with consciousness only found at the end of the process. Consciousness-related stimuli pick up strength as they progress through the cortex. After 200-300 ms unconscious processing fades, but consciousness-related signals move towards the front of the brain.
