Classical conditioning Flashcards
Define learning
A relatively permanent change in behaviour due to experience.
What is the learning curve
Picture
The more you practice the greater you accuracy of recalling or demonstrating learned material
What’s an example of something that can’t be learned
Reflex actions
Define memory
The process of encoding, storage and retrieval of information
Why is memory not a perfect replica of the world
It is a personal interpretation
Can change over time
Memories can be lost
Define neural plasticity
The ability of the brain to change itself in response to the environment. Neural connections are formed, removed or remade on a continual basis
What is developmental plasticity
Development and consolidation of neural pathways
Occurs mostly in infants, children and adolescence
What are the steps of developmental plasticity
Proliferation-cells divide and multiply
Migration- the movement of newly formed neurons (eg. Motor neurons to muscles of glands)
Circuit formation- neurones forming connections
Circuit pruning- getting rid of anything not needed
Myelination- strengthening neurones by insulating.
Thing to remember steps of developmental plasticity

What is adaptive plasticity
The ability of the brain to change and develop as a result of new experiences
Occurs in adults
Can develop and recover from serious injury
Two forms of adaptive plasticity
Sprouting- brand new neural connections (new pathways)
Re-routing- using a pre exciting pathways but it is different (finding another connection)
What is synaptogenisis
Creating new synapses and connections same as circuit formation
Define long term potentiation
Long lasting strengthening of synaptic connections, enhanced and effective synaptic transmission due to high frequency stimulation of synaptic pathway
What’s an example of long term potentiation
Practicing something
What is hebbian theory rule
“Neurones that fire together wire together”
How can long term potentiation be negative
