Anatomy & Amnesia Flashcards
Which of the following is generally agreed about the neural basis of memory functions?
A. That structures in the medial temporal lobe contribute importantly to normal memory processes.
B. That the roles of subdivisions of the medial temporal lobes are distinct and have been well defined.
C. That the structures in the medial temporal lobe contribute to memory, but not perceptual, processes.
D. That memories are encoded in medial temporal lobe structures.
A. That structures in the medial temporal lobe contribute importantly to normal memory processes.
Which of the following is NOT TRUE about the anatomy of the medial temporal lobes?
A. The fusiform gyrus lies laterally adjacent to the perirhinal and parahippocampal cortices.
B. The amygdala is anterior to the hippocampus.
C. The hippocampus is a region within temporal lobe neocortex.
D. The perirhinal cortex lies anterior to the parahippocampal cortex.
C. The hippocampus is a region within temporal lobe neocortex.
The well-studied amnesic, Clive Wearing, who has a very dense amnesia and additional impairment of some semantic memory functions has damage to:
A. The hippocampus and the perirhinal cortex.
B. All of the medial temporal lobe structures and additional inferior and middle temporal lobe cortex.
C. The hippocampus and the parahippocampal gyrus.
D. All of the medial temporal lobe structures.
B. All of the medial temporal lobe structures and additional inferior and middle temporal lobe cortex.
Many tragic effects resulted from the extensive lesions suffered by Clive Wearing. However, which of the following IS NOT demonstrated by this case?
A. That very extensive damage to medially lying parts of the temporal lobe produces generalized dementia.
B. That very extensive damage to medially lying parts of the temporal lobe can destroy the ability to learn new memories.
C. That very extensive damage to medially lying parts of the temporal lobe can spare many intellectual functions and forms of expertise.
D. That very extensive damage to medially lying parts of the temporal lobe can affect personality.
A. That very extensive damage to medially lying parts of the temporal lobe produces generalized dementia.
Agnosia is:
A. a generalized intellectual disorder in which patients lose general knowledge about objects and concepts
B. the selective loss of knowledge of object meaning or attributes without general cognitive dysfunction
C. the selective loss of ability to name objects
D. the inability to learn and remember new information about events and episodes from one’s life
B. the selective loss of knowledge of object meaning or attributes without general cognitive dysfunction
