This anatomical feature ensures that the left visual field of both eyes is processed by the right hemisphere of the brain, and vice versa. The dorsal stream, or the "where pathway," focuses on spatial awareness and the localization of objects in space.

The Role of the Retina The retina is not merely a passive screen; it is a dynamic neurosensory tissue that performs the critical conversion of light into neural code. The ventral stream, often termed the "what pathway," is involved in object recognition and identification.
The iris adjusts the size of the pupil to regulate the amount of light, protecting the sensitive inner structures. Here, the brain analyzes basic components such as orientation, spatial frequency, and color.

Instead, they first pass through a complex network of interneurons within the retina itself. The vision process is a sophisticated sequence of events that transforms light into the rich, three-dimensional perception of our surroundings.
