Brain and behaviour: Neuroplasticity Flashcards
Neuroplasticity
Refers to the brains ability to alter its own structure following changes within the body or external environment, such as learning or experience
What is functional neuroplasticity?
Brains functions move from a damaged area to an undamaged area
Structural neuroplasticity
The brains ability to change it’s neuronal connections and adapt
What are some examples of neuroplasticity?
- Someone who is blind: Their brain may adapt to being blind by using other senses more
- As they do this there sensory skills become more sensitive, so that their touch or hearing senses are far more practised than someone who is sighted
Dendritic branching
Connection of neurons which create a new trace in the brain every-time we learn something new
Arborisation
The growth of dendritic branches, which gains information from other neurons and form new dendrites which grow to gather more information
Hippocampus
Part of the brain that is responsible for consolidation of memory from the short-term to the long-term
Dendritic pruning
Where synaptic connections are removed, this could be due to irrelevant information or stress/trauma which is considered ‘unimportant’
Action potential
A change in electric potential that travels through a neuron during the release of a neurotransmitter into the synapse
What is long-term potentiation?
(LTP) is where the synapses become stronger over repeated use
Over a longer time of practice/use there is more potential
