primary
Lesion to the sensory association area = what two possibilities ?
- tactile agnosia
2. astereognosis
________ agnosia = inability to interpret the significance of sensory information
tactile
_________ = the inability to recognize an object placed the hand
astereognosis
_______ organization = how pitch is represented at the primary auditory cortex.
tonotopic
______ = involved in addiction and processing taste.
insula
Parietal association areas = involved in what three things ?
- Attention
- Awareness of self
- Awareness of extrapersonal space
What is the role of the connection between the parietal and frontal areas?
focus on stimulus and filter out direction
Attention to the R side of the world is controlled by both hemispheres, so a stroke to the left hemisphere will not result in right neglect (T/F).
TRUE
Attention to the L side of the world is controlled by both hemispheres, so a stroke to the right hemisphere will not result in left neglect (T/F).
