Cellular basis of learning and memory
Cards in this deck (9)
- 1Define learning and memoryLearning - A change in behaviour following an experience
Memory - storage and ability to recall a learned experience - 2What is the difference between associative and non - associative learning. Give an example for eachNon-associative learning = a relatively permanent change in the strength of response to a single stimulus due to repeated exposure to that stimulus. An example of which is habituation
Associative learning = A process by which someone learns an association between two stimuli e.g. classic conditioning - 3What are the two main approaches to study implicit memory?Black box and Reductionist
- 4Why is Aplysia used as a model for studying learning and memory?The nervous system has a small number of cells
The cells are very large - 5What is the proposed model for long term sensitisation?What causes With repeated serotonin exposure PKA moves to the nucleus and phosphorylates a transcription factor for immediate early genes
Immediate early genes are themselves TFs for late responsive genes which encode proteins needed for new synapse formation - 6What causes synaptic pruning?Long-term depression
- 7For Pavlovian conditioning to occur what needs to happen?A neutral stimulus and a stimulus which causes an innate response need to occur with precise timing
The size of the response changes with the distance in time between the two stimuli - 8What happens if the unconditioned stimulus (innate response stimulus) occurs before the conditioned one (neutral stimulus)?No learning occurs
- 9Define the term ‘configural property’ in the context of visual prey recognition in toadsNeither shape nor direction of movement alone are sufficient for the response – it’s the relationship between the two that matters i.e., the ‘whole’ stimulus is greater than the sum of its parts.
