Lecture 5 Flashcards
Describe:
Temporal Lobe
- Second largest lobe
- Located beneath lateral fissure
- Very cognitive
Describe the function of:
Temporal Lobe
Very cognitive
* Visual object and face recognition
* Memory formation
* Episodic, semantic, and spatial memory
* Language processing/receptive language ability
Describe:
The differences between episodic, semantic, and spatial memory
Episodic: Personally relevant memories
Semantic: Fact-based memories
Spatial: Navigation (neurons in temporal lobe work with hippocampus to form spatial location memory)
Where is language processing/receptive language ability present?
Left temporal lobe
Define:
Visual agnosia
Lesion of temporal lobe where people cannot recognize familiar objects
True or False:
Visual Agnosia becomes more prevalent with aging
False, visual agnosia doesn’t have anything to do with age but has things to do with the later stages of visual processing
What causes fluent/Wernicke’s aphasia?
Left temporal lobe lesion
What are hallmark symbols of fluent/Wernicke’s Aphasia?
Speech is effortless, but a jumble of words that doesn’t have any meaning
Describe:
Parietal Lobe
- Located above temporal lobe, behind central sulcus and anterior to the parieto-occipital sulcus
- Divided into superior (SPL) and inferior (IPL) parietal lobes
- Sensory to motor interface
What is immediately posterior to the central sulcus?
The primary somatosensory cortex (S1)
List:
SPL and IPL functions
SPL is involved in feedback control
IPL is involved in movement planning
Sum up the processes/tasks the parietal lobe is involved in
- Visuomotor transformations
- Movement planning
- Spatial orientation of self, corporal self-recognition (recognizing their own body parts)
- Numerical processing
- Visual-spatial processing
Describe:
Alien hand syndrome
Can be caused by a lesion to parietal lobe (tends to be transient - short-lasting - during recovery of stroke)
Can have “evil” hands that fight themselves
Describe:
Dyscalculia
Numerical processing deficit can occur after left hemisphere deficit
When do visual-spatial/hemi-spatial neglect usually occur?
Typically occurs after lesion to right hemisphere parietal lobe
