Memory (T) Flashcards
The difference between a lobectomy and a lobotomy is that…
Lobectomy: removal of lobe
Lobotomy: separation of lobe
Retrograde amnesia is
Loss of memory from before the damage
With anterograde amnesia, you can’t ______ memories
Form new
HM’s performance on the BLOCK-TAPPING test suggested he had….
Global amnesia (all senses)
HM’s procedural/episodic/semantic memory was still intact
Procedural
What did the case of HM suggest regarding memory storage?
Different modes of storage for STM and LTM (and explicit and implicit)
What is cerebral ischemia?
Interruption of blood supply to brain
What is the specific vitamin deficiency that accompanies Korkasoff’s?
Thiamine
Korkasoff’s Syndrome begins as anterograde, but can progress…
To retrograde in its later stages
Test for animal LTM?
Delayed non-match sample test
The delayed non-match to sample test tests the assumption that…
Amnesia from medial temporal lobe damage results from hippocampal damage
Why was the delayed non-match to sample test repeated in rats?
In monkeys, HC lesions involves damaging larger portions of cortex as well
In rats, bilateral surgical removal of the hippocampus produced…
Moderate/no deficits in the test
People, monkeys and rats with ischemic damage have severe deficits in…
Object recognition
People, monkeys and rats with ischemic damage have severe deficits in object recognition. Why is this?
Ischemia –> hyperactivity of glutamate
Widespread damage outside of hippocampus too
