- Some information from the primary visual cortex stretches' dorsally toward the parietal lobe
- This stream is speculated to assist in the analysis of visual motion and the visual control of action

Dorsal Stream

- Some information from the primary cortex extends ventrally towards the temporal lobe
- This is called the ventral stream
- Consists of several brain regions, thought to be involved in the perception of the visual world and the recognition of objects

Ventral Stream

University of Colorado at Boulder

- The visual cortex has many regions that process visual information
- Most visual information passes through the primary visual cortex, or area V1 or Brodmann area 17
- There are many other areas of the visual cortex that have important roles in vision

Neuroscience: Exploring the Brain

The primary visual cortex (V1) has a highly structured organization, which was largely uncovered by the research of David Hubel and Torsten Wiesel. It represents four main dimensions of visual stimuli:
- Location in the visual field
- Ocular dominance
- Orientation
- Color

Organization of primary visual cortex

- Some retinal ganglion cells are most responsive to movement in a specific direction.
- Neurons in V5 receive these signals that are crucial for movement perception.
- These neurons are near the regions that control eye movements.
