Lecture 12 Flashcards
Where are retinal ganglion cells present?
More present in central vision than peripheral vision, projects larger expanse in primary visual cortex, creating more clear images in the central vision
What is lateral field asymmetry?
Asymmetry moving between left and right
Describe:
Lower and upper visual field asymmetry
- Superior and Inferior hemiretina receives information from each visual field
- More retinal ganglion cells in the superior hemiretina
When typing and writing, what visual field are you working and what hemiretina does that project to?
Lower visual field
Superior hemiretina
When you lecture to an audience, what visual field and hemiretina are you using?
Upper visual field
Inferior hemiretina
True or False:
Lower visual field has better response time and is more accurate than upper visual field
True
Why to people tend to look up when they think about challenging questions?
The upper visual field has better access to cognitive ability
What is the lower visual field related to?
Various movement
Define and describe:
Broca’s Aphasia
Difficulty producing language
Also known as Non-fluent Aphasia
Define and describe:
Wernicke’s Aphasia
Difficulty understanding language
Also known as Fluent Aphasia or word salad
Describe:
Conductio Aphasia
Also known as Disconnection Syndrome
* No longer able to communicate between Wernicke’s and Broca’s region
Define:
Arcuate fasciculus
Bundle of axons connecting Wernicke’s to Broca’s area
What is a fasciculi?
Any bundles of nerves
True or False:
Autonomic speech tends to be represented in left hemisphere
False, it tends to be bilaterally represented (both in left and right hemisphere)
Define:
Anomia
Word finding challenge
