In monkeys and humans, the cortical regions that make up the object recognition pathway are directly adjacent to the primary visual cortex (V1) in the occipital lobe and gradually extend into the more anterior and ventral portions of the temporal lobe.
Where is the ventral tract located?
The ventral flow originates in the primary visual cortex and extends along the ventral surface into the temporal cortex. Dorsal flow also occurs in the primary visual cortex but continues along the dorsal surface into the parietal cortex.
Which areas of the brain belong to the ventral pathway?
The ventral pathway has been described as passing through the occipitotemporal cortex to the anterior portion of the inferior temporal gyrus (TE zone)[1, 2], with a probable extension into the ventrolateral prefrontal cortex (VLPFC/FDv zone)[3] .
What is the pathway to the primary visual cortex?
The primary visual pathway includes the retina, the optic nerve, the lateral geniculate nucleus (LGN) of the thalamus, and the visual cortex of the occipital lobe. Each of these structures work in turn to transform the visual signal, resulting in our visual perception of the outside world.
What is the way of speaking?
The ventral auditory pathway is responsible for detecting sounds and is therefore referred to as the what auditory pathway. The dorsal auditory stream in humans and non-human primates is responsible for sound localization and is therefore referred to as the Wo auditory pathway.
Where are the ventral and dorsal orbits?
It describes two information processing streams from the occipital cortex, dorsal (going to the parietal cortex) and ventral (going to the temporal cortex), which show relative specialization in object recognition (what) and spatial vision (where).
Where is the which pathway located in the brain?
The ventral stream (aka the what pathway) leads to the temporal lobe, which is involved in visual and object identification and recognition.
Where is the back route?
a pathway that carries visual information from the primary visual cortex to the parietal lobe.
What is the way and where is the way?
In the currently dominant view, the various maps are organized hierarchically into two main pathways, one involved in recognition and memory (the ventral flow or was pathway) and the other involved in action programming (the flow backend or where path).
What is the pathway to the visual cortex?
The vast majority of nerve fibers from the visual tract project to the lateral geniculate nucleus (LGN) in the dorsal part of the thalamus. The LGN is the main relay on the way to the primary visual cortex. The projection from the LGN to the visual cortex is called optic radiation.
What are the main pathways of the visual cortex?
This provides information about the depth of objects. In addition to the primary visual pathways, two other major visual pathways can be distinguished: the tectal or collicular pathway and the pretectal nuclear pathway. Therefore, not all optical fibers go to the lateral geniculate body.
What is the correct order of the visual pathways?
The visual journey. The visual pathway includes the retina, optic nerves, optic chiasm, visual pathways, lateral geniculate bodies, visual rays, and visual cortex.
What is the visual pathway of the eye?
The visual pathway refers to the anatomical structures responsible for converting light energy into electrical action potentials that can be interpreted by the brain. It starts at the level of the retina and ends at the level of the primary visual cortex (with multiple intercortical pathways).
