Memory Flashcards
What is the definition of learning?
Relatively permanent change in behaviour due to experience
What is the definition of memory?
An active process that receives, organises, stores and recovers information when needed.
What is synaptic plasticity?
The ability of a synapse to change over time in order to become more efficient
What is long term potentiation
The long term strengthening of synaptic connections
What’s the role of LTP
To create more effective synaptic transmission
What is long term depression?
The long term weakening of synaptic connections
What is the role of LTD?
To create less effective synaptic transmission
This makes room to form new memories
What is synaptogenesis?
The formation of synapses between neurons
What is a key difference between neurotransmitters and neurohormones
- NT released at the synapse, NH released into the bloodstream
- NTs can only act as NTs, NH can act as both NT or NH
- NT message travels quicker than NH (less distance to travel)
Does adrenaline play a role in forming memories?
Yes, adrenaline plays a critical role in consolidating memories which are stressful or emotionally arousing.
What is consolidation?
The process of making newly formed memories stable after learning
What is the role of the amygdala?
Consolidation of implicit memories with emotional components
What is the role of the cerebellum (in forming memory)
Encodes implicit memories created by classical conditioning, requiring motor control, coordination and balance
What is stored in the cerebral cortex
Declarative and procedural memories
What is the role of the hippocampus
Encodes explicit memories from STM to LTM
What is the role of the prefrontal cortex in memory.
Processes STM so they can be sent to the appropriate lobe and linked to LTM
Which part of the brain is responsible for spatial memories?
Parietal lobe
Which part of the brain is responsible for facial recognition?
Occipital lobe
What part of the brain is responsible for auditory information of language?
Temporal lobe
