Document Summary

Habituation: response goes down sensitization: response goes up habituation regular basis: Outside in the cold, don"t feel it anymore, Heat and pressure of shoes: get used to it this is learning because your response changes drugs: tolerance video: sensitization. Kazoo- dog became more and more responsive to the annoying kazoo. got more and more sensitive to it. People talking behind you in lecture, tapping your chair. Aplysia slugs: has a very simple nervous system the nervous system is capable of learning displays sensitization processing cells in brain are neurons neurons always look like this axon attaches to other cells. synaptic cleft. Neurotransmitters (nt) cross the synaptic cleft. chemical communication vesicles have nt in them action potential comes down, activates calcium channels calcium helps the docking of the vesicles. need calcium to release nt. (exocytosis) Sensitization, more complex response which isn"t reversed easily habituation/sensitization reversible? sensitization: can change the emotional tone of the stimulus.
