The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
The visual pathway consists of structures that carry visual information from the retina to the brain.Lesions in that pathway cause a variety of visual field defects. In the visual system of human eye, the visual information processed by retinal photoreceptor cells travel in the following way:
The tectopulvinar pathway is a fast-acting pathway that provides the viewer with information on the absolute spatial information of objects. The pathway plays a large role in directing visual spatial attention and is particularly responsive to novel stimuli that appear or move in peripheral vision; however, because it receives mostly magnocellular visual input, the tectopulvinar pathway is not ...
Diagram of lateralized visual pathways of the human brain. The Divided Visual Field Paradigm is an experimental technique that involves measuring task performance when visual stimuli are presented on the left or right visual hemifields. If a visual stimulus appears in the left visual field (LVF), the visual information is initially projected to ...
Visual representation of the parvocellular and magnocellular pathways. From the LGN, the M pathway continues by sending information to the interblob regions of the 4Cα layer of the V1 region of the visual cortex, also called the "striate cortex". [6] Other cells in the striate are more influenced from signaling from P cells and yet others from ...
The pathway helps to connect parts of the brain or nervous system that are distant, and are typically known and seen as white matter. In the vision pathway, visual information leaves the eye with the help of the optic nerve. Axons partially cross in the middle of the optic chiasm.
There is a traditional view that visual processing follows a feedforward system where there is a one-way process by which light is sent from the retina to higher cortical areas, however, there is increasing evidence that visual pathways operate bidirectionally, with both feedforward and feedback mechanisms in place that transmit information to ...
