Topic 8 - Habituation and Sensitisation
Cards in this deck (10)
- 1Memory- not localised in brain
- stored/created in patterns of connections and strength of synapses. - 2Who did the experiment with slugs? What type of slug? Why?Eric Kandel
Sea Slugs. Same neurones just less. - 3Slug experiment- gill withdraws when siphon stimulated
- too many times and it stops
- Habituation allows to focus on more threatening or rewarding stimuli - 4Habituation Biochemistry- Ca2+ channels less responsive with more stimulation
- less Ca2+ so less NT
- less depolarisation until no AP in postsynaptic - 5Long-term Memory- entails more synaptic connections
- Repeated use of a synapse --> more made - 6Sensitisation- if give electric shock to tail, other stimuli more strongly reacted to
- Seretonin released by crash, so more Ca2+ - 7Animal Testing- animal rights
- animal welfare
- utilitarianism - 8Animal rightsneed consent from animals
assumes animals feel pain and pleasure - 9Animal Welfare- more popular than animal rights
- EU bans vertebrate testing with non-animal alternatives
- assumes animals feel pain and pleasure - 10UtilitarianismTest animals only if expected results are more substantial than animal's suffering.
