Synaptic plasticity (2D) Flashcards
What is synaptic plasticity?
The ability of synaptic connections to change over time in response to activity or experience.
Name the three mechanisms of synaptic plasticity.
Sprouting
Rerouting
Pruning
What does sprouting involve?
The ability of dendrites or axons to develop new extensions or branches.
What does rerouting involve?
the ability of a neuron that is connected to a damaged neuron to create an alternative synaptic connection with an undamaged neuron.
What does pruning involve?
the elimination of synaptic connections that are not adequately activated.
What is the definition of learning?
The process of acquiring knowledge, skills or behaviours through experience.
What is the definition of memory?
The process of encoding, storing and retrieving information that has been previously encountered.
What is long term potentiation?
The long lasting and experience dependent strengthening of synaptic connections that are regularly coactivated.
What neurochemical has an important role in synaptic plasticity?
Glutamate
How does glutamate assist in synaptic plasticity?
It strengthens the synaptic connections between neurons that are regularly coactivated.
What is the phrase to remember long term potentiation?
Neurons that fire together wire together
What is long term depression?
The long lasting and experience dependent weakening of synaptic connections between neurons that are not regularly coactivated.
