Unit 3 : AOS 2 Flashcards
1
Q
LTP, LTD Similarities
A
-both play an important part in the process of neuroplasticity.
-both involve long-lasting changes to the synaptic connections and the structure of neurons.
-The hippocampus is the structure in the brain most
affected by these two processes and has a role in memory and learning.
2
Q
LTP
A
- Strength of flow of information between neurons increases and there is increased efficiency in neural transmission.
- More neurotransmitters released from the presynaptic neuron.
- More action potentials occur in the presynaptic neuron.
- More receptors appear on the postsynaptic neuron
- Longer and/or more dendritic spines – dendrites become ‘bushier’.
- Axon sprouting
3
Q
LTD
A
- Strength of flow of information between neurons decreases and there is decreased efficiency in neural transmission.
- Fewer neurotransmitters released from the presynaptic neuron.
- Fewer action potentials occur in the presynaptic neuron.
- Amount of receptors decrease on the postsynaptic neuron
- Dendritic spines become shorter and/or less ‘bushy’.
- Axon pruning.
4
Q
neural plasticity and memory
A
-Memory: An active information system that receives, organizes, stores and recovers information when we need it
5
Q
neural plasticity and learning
A
-Learning: A relatively permanent change in behavior due to experience
