procedural / response memory Flashcards
1
Q
Packard & McGaugh (1996)
A
- rats “overtrained” i.e. trained for 2 weeks then maze rotated and rats tested = response strategy
- so initially, place memory and cognitive map guided acquisition of memory (learning task) then switched to response memory as habit developed
- lidocaine into striatum abolished “response” memory in week 2 (but still could do task as could use place memory)
2
Q
cued radial arm maze (olton) and morris water maze
A
- use response strategy if they are cued e.g. with a light (associative learning only)
- not impaired by HC lesion
3
Q
Cook & Kesner (1988)
A
- rats with striatum lesion = impaired on response tasks e.g. visual discriminant water maze, or turning right on arm of maze through habit
- normal performance on place tasks using cognitive map e.g. normal radial arm maze / spatial discriminant water maze
4
Q
Kernadi (1995)
A
- monkeys trained to follow certain sequence of dots then repeat pattern by fixating each location in order of presentation, then reaching to target position
- some striatal neurons respond to particular location but only within certain sequence
5
Q
Thompson (1994)
A
- rabbit pavlovian eye blink conditioning
- tone/light (CS) then air puff to eyelid (US) = reflexive eye blink (UR)
- several CS-US pairings = CR to CS
- lesion interpositus nucleus in cerebellar cortex = CR not learnt
- inactivation of red nucleus (between cerebellar cortex and motor cortex) = CR learnt but can’t be produced until inactivation reversed (only prevents motor output from cerebellum to cortex)
association builds up in cerebellum and feeds out to motor nuclei
6
Q
Scoville & Milner 1957 / Milner 1972
A
- HM had intact procedural learning e.g. mirror drawing
- also intact priming, both perceptual e.g. Gollins picture task and semantic e.g. word association
7
Q
Cohen + Squire
A
distinction between declarative and procedural memory
8
Q
Squire + Zola-Morgan 1991
A
HC lesioned monkeys can acquire procedural skills (independent of MTL)
