BRAIN PARTS | Visual Pathways | Eye or Brain? | Terminology | CNVR Program |
---|---|---|---|---|
What is the Occipital lobe?
This lobe of the brain is responsible for visual processing
|
What is Binocular visual?
The visual fields of both eyes overlap to create this visual field
|
What is the Retina?
A light-sensitive tissue lining the inner surface of the eye is considered part of the central nervous system (CNS) and is actually brain tissue
|
What is Acquired brain injury?
This is a term that can be applied to all types of brain injury that occurs after birth, and may include all traumatic brain injuries, or even injuries caused by stroke
|
Who is Katie Taylor?
CNVR Coordinator
|
What are the Neurons?
These are the "communicators" of the nervous system which is made of billions of these and each has a cell body, axon and dendrites
|
What is the Left visual?
A lesion of the right optic track causes a complete loss of vision in this hemifield
|
What is the Optic Nerve?
Also known as cranial nerve 2, this transmits visual information from the retina to the brain
|
What is Anoxia/Anoxic?
This term is used when there has been a lack of oxygen getting to the brain
|
What is 20?
How many lights are on the NVT panel?
|
What is the Frontal lobe?
This lobe is responsible for initiating actions, controlling emotions, problem solving, decision making and other executive like functions
|
What is are the Dorsal and ventral streams?
These two visual cortical areas beyond the visual cortex form two information processing streams dedicated to recognition and the spatial relationships of objects

What is Aphasia?
This term refers to difficulty understanding speech
and/or difficulty with expressing thoughts |
What is TBI- Traumatic Brain Injury?
A form of acquired brain injury, occurs when a sudden trauma causes damage to the brain
|
What is the Parietal Lobe?
This lobe is located a the top of the brain and merges into the occipital lobe. It responds to touch, heat, cold, pain and body awareness; injury can cause a loss of these sensing abilities (see image 1)
|
What are the Nasal fibers?
Of the visual pathways, these nerve fibers
cross over at the optic chiasm |
What is Visual Perception?
This process refers the brain’s ability to make sense of what the eyes see
|
What is Apraxia?
This term refers to the inability to conduct purposeful movement
|
What are Red, Green, Blue, White and Orange/Yellow?
These are the colors of of lights on the NVT panel
|
Dorso-lateral pre-frontal cortex
Basal Ganglia Cingulate gyrus Cerebellum
Name 2 interval timing structures in the Brain
|
What is the thalamus (Lateral Geniculate Nucleus)?
The optic tracts project primarily here, before reaching the primary visual cortex in the occipital lobe.
|
What is both the eye and the brain?
Is the eye or the brain is responsible for the perception of movement.
|
What is Akinesia?
This term refers to slowness and loss of movement.
|
What are Saccades?
Quick, simultaneous movements of both eyes between two or more phases of fixation in the same direction
