Classical Conditioning Flashcards
Conditioned Stimulus (CS)
Tone, light or tactile stimulus that triggers.
Unconditioned stimulus
Stimulus that leads to automatic response.
Unconditioned response
Unlearned response that occurs naturally in reaction to the unconditioned stimulus.
Conditioned Response
Automatic response triggered by training of stimulus.
Delay vs trace conditioning
US and CS cotermination. This requires the cerebellum.
Trace there is a gap between CS offset and US onset. This requires cerebellum and hippocampus.
Pseudoconditioning vs differential conditioning
Unpaired CS and US presentation.
CS+ and CS-, with unpaired/pair US.
Thompson Paper, The Engram Found.
What did cerebellar lesion result in with regards to conditioning?
Found that cerebellar lesion prevents CR acquisition in eye ipsilateral to lesion. It cannot learn new conditioned response either.
Contralateral eye can still learn and make CRS.
Yeo et al. what cerebellar cortex lesions resulted in what? What did they discover the CBM did and what part of the CBM did it?
Lesions to lobule VI disrupts CRs to ipsilateral eye.
ANTERIOR CBM cortex important for timing of the CR. Posterior damage timing was normal.
Draw the Essential Circuitry for EBCC.
Look at Ipad!
Pons and Mossy Fibers: Which stimulus does that match to? What does lesion to the auditory-response pons cause?
Conditioned Auditory Stimulus. Lesions to pons cause elimination of CR to CS.
Role of inferior olive in EBCC.
What happens when you lesion inferior olive?
Inferior olive responds to US.
Extinction of CR
Red Nucleus in EBCC.
What happens when you cool the RN?
Receives projections from the interpositus.
No CR activity in the RN. You do see activity in the interpositus because the CBM is learning but it cannot express that learning bc the RN is cooled.
True or False: Cooling of the RD prevents CR but not learning.
TRUE!
True or False: Inferior olive and climbing fiber stimulation cannot be used as US to support conditioning.
False!
True or False: Pons and mossy fiber stimulation can be used as CS to support conditioning.
True!
