The ventral (“what”) pathway
is usually described as processing objects, whereas the dorsal (“where”) pathway is described as processing space (although the two pathways have also been described as processing perception [“what”] vs.
What is the pathway that supports object recognition?
The ventral stream
(also known as the “what pathway”) leads to the temporal lobe, which is involved with object and visual identification and recognition.
What does the ventral pathway determine?
a pathway that carries visual information from the primary visual cortex to the temporal lobe. According to one widely-accepted hypothesis, the ventral stream (so named because of the path it takes along the ventral side of the brain)
carries information related to object form and recognition
.
What are the what and where pathways?
In the currently prevailing view, the different maps are organised hierarchically into two major pathways, one involved in recognition and memory (the
ventral stream
or ‘what’ pathway) and the other in the programming of action (the dorsal stream or ‘where’ pathway).
What is dorsal pathway?
Definition. The dorsal visual pathway is
a functional stream originating in primary visual cortex and terminating in the superior parietal lobule
that is responsible for the localization of objects in space and for action-oriented behaviors that depend on the perception of space.
How do humans recognize objects?
You remember an object
by its shape and inherent features
. … We have cells in our visual cortex that respond to simple shapes like lines and curves. As we move along the ventral stream, we get more complex cells which respond to more complex objects like faces, cars etc.
Which side of the brain controls object recognition?
Structural processing:
the lateral occipital complex
The lateral occipital complex (LOC) has been found to be particularly important for object recognition at the perceptual structural level.
What is the difference between the ventral and dorsal pathways?
The ventral stream (or “vision-for-perception” pathway) is believed to mainly subserve recognition and discrimination of visual shapes and objects, whereas the dorsal stream (or “vision-for-action” pathway) has been primarily associated with
visually guided
reaching and grasping based on the moment-to-moment analysis …
What brain areas are part of the ventral pathway?
The ventral pathway was described as coursing through the occipitotemporal cortex to
the anterior part of the inferior temporal gyrus (area TE)[1
, 2], with a likely extension into the ventrolateral prefrontal cortex (VLPFC/area FDv)[3].
Where does the ventral stream end and what type of information does it process?
Dorsal Stream which is tuned to where the object is and is the object moving. Whereas the Ventral Stream is
tuned to what is the object, what is the color of the object
, and what form it has. <br>The Dorsal Stream ends in the posterior parietal complex whereas the Ventral Stream ends at the inferior parietal complex.
What is the difference between path and pathway?
“Path” is the route that one takes to get from point A to point B. A “pathway”
must lead somewhere
, but that “somewhere” is not necessarily a physical location. Eg, a pathway to enlightenment, a pathway to mastering English.
What is the purpose of pathway?
Purpose Pathways require students to think differently about their education – instead of following a specific path determined by the institution, they are
empowered to construct their own path and identify institutions and experiences that help them move forward on it
.
What is the pathway to success?
Pathway to Success is a Johnson & Johnson (J&J) initiative, managed by FHI 360, that
builds college readiness and career opportunities for Bridge to Employment
(BTE) students and alumni.
What is the function of dorsal pathway?
a pathway that
carries visual information from the primary visual cortex to the parietal lobe
.
What happens if the dorsal pathway is damaged?
If either the dorsal or ventral stream is damaged, this leads to
dissociable behavioural deficits
. For example, patients with optic ataxia have lesions in parietal areas, which are part of the dorsal stream. They have deficits in reaching and grasping objects, but are able to visually discriminate different objects.
What does the dorsal do?
Dorsal:
Relating to the back or posterior of a structure
. As opposed to the ventral, or front, of the structure.
