Neuroplasticity Flashcards
what is neuroplasticity
the brain’s ability to reorganize and adapt to form new neural connection throughout life
what is habituation
decrease in neurotransmitters that are released to other neurons
what is the result of habituation
decrease in response to a repeated stimulus
what is long term potentiation
long lasting increase in synaptic efficacy following high frequency stimulation
what is Simon says an example of
long term potentiation
what is long term depression
decrease in synaptic efficacy following frequency stimulation
what is sensitization
more neurotransmitters released to other neurons
what is the result on sensitization
increase in neural response to repeated stimulus
what does structural neural plasticity increase or decrease
neurotransmitter release, postsynaptic receptors, axon terminal, and other neural connections
what is the main reason we used a sea slug to test for neuroplasticity instead of a human
complexity - humans have a lot more neurons
where does sensory info enter in the sea slug
siphon
what does the motor neuron of the sea slug cause to contract
gill
what happens to the contraction as we stimulate the siphon more
gets smaller - synapses weaken
what is it called when the synapses of the sea slug weakened
habituation
what happened when scientists combined 2 stimuli
gill contracted even more - synapse was stronger
what is called when the synapses of the sea slug got stronger
sensitization
