There is no visual pathway to (or from) the hands. This idea says objects near the hands are immediate candidates for action. It doesn't mention in any way that there is a visual pathway from the hands to the eyes.
Just means that you are more likely to use something nearby your hands (in sight) than some that are not (in sight).
This has "led us to hypothesize that vision near the hands would be biased toward the action-oriented magnocellular visual pathway that supports processing with high temporal resolution but low spatial resolution". ~From a published scientific article.

How is the visual pathway from the eyes different from the ears or hands?
each eye is not primarily connected to one hemisphere only instead, each visual half field is projected to the opposite hemisphere so, if an image is seen in the right visual field it would be seen in the left hemisphere and if an image is seen in the left visual field it would be seen in the right hemisphere
What is the anterior visual pathway?
The anterior visual pathway refers to the pathway that visual information takes from the eyes to the visual cortex in the brain. It includes the optic nerves, optic chiasm, optic tracts, and lateral geniculate nucleus. This pathway is responsible for transmitting visual signals from the retina to the brain for processing and interpretation.
Where does the second pathway of visual information go before it goes to the cortex?
The second pathway of visual information, known as the "where" pathway or the dorsal stream, primarily projects from the primary visual cortex (V1) to the parietal lobe. This pathway processes spatial awareness and motion, helping to determine the location and movement of objects in the visual field. Before reaching the cortex, visual information travels from the retina to the lateral geniculate nucleus (LGN) of the thalamus and then to V1.

What is the pathway of conscious visual sensation?
The pathway of conscious visual sensation begins when light enters the eye and is focused onto the retina, where photoreceptors (rods and cones) convert the light into electrical signals. These signals are then transmitted via the optic nerve to the lateral geniculate nucleus (LGN) in the thalamus. From the LGN, the information is relayed to the primary visual cortex (V1) in the occipital lobe, where conscious visual perception occurs, allowing us to interpret and understand visual stimuli. This pathway is crucial for processing aspects such as color, motion, and depth.

The optic radiations project to the?
The optic radiations project to the visual cortex in the occipital lobe of the brain. They carry visual information from the lateral geniculate nucleus of the thalamus to the primary visual cortex. This pathway is important for processing and interpreting visual stimuli.
What is the neural pathway for the eye?
The neural pathway for vision starts with photoreceptors in the retina that send signals through the optic nerve to the brain's visual cortex via the lateral geniculate nucleus of the thalamus. The visual cortex then processes and interprets these signals to create the sensation of vision.
What is the orgin of scotoma?
Scotoma originates from the Greek word skotoma, meaning "dizziness" or "giddiness." In medicine, it refers to a visual field defect caused by damage to the visual pathway or retina.
What is the first way station in the visual pathway from the eye?
The first way station in the visual pathway from the eye is the retina. Light enters the eye and is focused onto the retina, where photoreceptor cells convert the light into electrical signals that are then transmitted to the brain via the optic nerve.
Cortical blindness plus lesion in visual pathway?
Cortical blindness refers to the loss of vision due to damage in the visual cortex of the brain, despite intact eyes and optic nerves. When there is also a lesion in the visual pathway, such as in the optic nerve or optic tract, this can further impair visual processing and lead to additional visual deficits. The combination of these conditions may result in a more complex clinical picture, where the individual may experience varying degrees of visual impairment, depending on the extent and location of the lesions. Assessment and rehabilitation can be challenging, as the underlying causes of visual loss are multifaceted.
