Habituation Flashcards
1
Q
Define habituation
A
The reduction in neural signalling due to repeated stimulation, resulting in reduced release of neurotransmitter
2
Q
In sea slugs what causes the gill to withdraw
A
Sensory neurones contact motor neurones which causes gill to withdraw
3
Q
What happens to the sensory neurone if it is repeatedly stimulated
A
The calcium channels become less sensitive to depolarisation
4
Q
What happens as a result of calcium channels becoming less sensitive to depolarisation
A
Fewer synaptic vesicles leave the sensory neurone
5
Q
What is the result of few synaptic vesicles leaving the sensory neurone
A
Motor neurone gets stimulated less and less retraction in the gill
