Conditioning + Learning

Front 1

The Interpositus Nucleus

Back 1

A cluster of neuronal cell bodies located in the cerebellum in the region of the brain stem

Front 2

What is the role of the Interpositus Nucleus?

Back 2

gives the ability to detect CS-US relation

Front 3

If the IN is a learning neuron

Back 3

*Then lesioning the IN disables the learning process.

*The CS-US pairing experienced while the IN is lesioned will not influence the linkage between CS and US.

*The learning neuron must be operational at the time that the subject experiences the CS-US pairing, otherwise the subject will not appreciate that the tone CS is paired with the shock US

Front 4

If the IN is a CR motor performance neuron

Back 4

*Then lesioning the IN impairs the efferent or output end of the neural network.

*Lesioning the IN makes it impossible for the subject to perform the CR, because the subject is essentially paralyzed.

*But, the subject is not learning disabled. The subject learns that the CS is a signal for the US.

*If not paralyzed, the subject would react to the presentation of the CS by performing the CR.

Front 5

Goal-Trackers

Back 5

react to the insertion of the lever CS by approaching the location of the receptacle where the food US is delivered

Front 6

Sign-Trackers

Back 6

approach and consume the lever CS

Front 7

delay discounting

Back 7

the discounting of the value of the larger reward by the negative effect for waiting through the delay interval

Front 8

If the columns differ it is a

Back 8

performance neuron

Front 9

If the rows differ it is a

Back 9

CR motor neuron

Front 10

distributed practice condition produces

Back 10

better CR performance because the long wait

Front 11

massed practice condition produces

Back 11

worse CR performance

Front 12

Abstinence

Back 12

swear you will not do it anymore; you will remain “drug free”… however during this time you have a false sense of “control”

Front 13

Lapse

Back 13

That false sense of “control” causes you to fall back into feel that you will have a handle on taking the drug; however, taking this drug after a long period of inaction causes a strong CR performance;

Front 14

Relapse

Back 14

Rapid-fire drug taking/ binge
