What does the ventral pathway do?
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 is the ventral pathway for quizlet?
Also known as the ventral pathway, this stream of processing descends from the occipital cortex to the inferior temporal cortex and is involved in objects recognition. It is often referred to as the 'what' pathway owingtoits primary function.
What is the ventral pathway in vision?
In particular, we argue that the ventral visual pathway is a recurrent and highly interactive occipitotemporal network linking early visual areas and the anterior inferior temporal cortex along multiple routes through which visual information is processed.
Where is the ventral pathway located?
temporal cortexThe ventral stream originates in primary visual cortex and extends along the ventral surface into the temporal cortex; the dorsal stream also arises in primary visual cortex, but continues along the dorsal surface into parietal cortex.
What are some of the differences in processing in the dorsal and ventral visual pathways?
From their model, the ventral stream processes visual information for the purpose of visual perception (“vision for perception”), while the dorsal stream processes visual information for the purpose of executing movements (“vision for action”).
What are the two pathways of visual streams for visual processing in the human brain quizlet?
functionally, the dorsal stream is responsible for spatial recognition, and the ventral stream is responsible for object recognition.
What happens if the ventral visual pathway is damaged?
Ventral damage can cause: Impairments in contrast sensitivity, form and color vision, and depth perception. Impairments in object and face perception and route-finding.
Where in the brain does the ventral pathway end?
From there, the ventral pathway goes through V2 and V4 to areas of the inferior temporal lobe: PIT (posterior inferotemporal), CIT (central inferotemporal), and AIT (anterior inferotemporal).
What is the dorsal pathway responsible for?
According to one widely-accepted hypothesis, the dorsal stream (so named because of the path it takes along the dorsal side of the brain) carries information related to movement and spatial relationships between objects in the visual field. It is sometimes called the "where" pathway.
What is the ventral part of the brain?
directional term that refers to the front. When used in reference to the nervous system, ventral refers to the front when discussing the spinal cord. However, above the junction of the midbrain and diencephalon, ventral refers instead to the lower or inferior portion of the brain.
Which is the ventral side of the brain?

What type of processing is accomplished by the dorsal path?
The dorsal stream (or, "where pathway") leads to the parietal lobe, which is involved with processing the object's spatial location relative to the viewer and with speech repetition.
Where will the tracts indicated by the letter D terminate quizlet?
The spinothalamic tracts indicated by D carry somatosensory information and terminate in the thalamus.
Which of the following is not a function of the hypothalamus group of answer choices?
Answer and Explanation: (C) Postural reflexes are NOT a function of the hypothalamus.
