PSYB64H3 Chapter Notes - Chapter 12: Explicit Memory, Brainstem, Tempora
Document Summary
Ho1: with repeated stimulation, the sensory neurons serving the siphon might become less responsive discarded. Ho2: a reduction in the gill muscle"s ability to react in response to input from the motor neurons ruled out. The repeated stimulation depletes the amount of available neurotransmitter in the presynaptic sensory neuron, producing a type of short-term habituation within-session habituation. Cs: a slight touch of the mantel shelf. Classical conditioning: the change in the ability of cs to elicit strong gill-withdrawal reflexes: in contrast, no changes are observed in animal"s response to the siphon touch (cs), which has never been paired with shock (ucs) Whenever large concentrations of calcium are present, the process leading to potassium channel closing are enhanced. The arrival of the signal from the cs at the sensory axon terminal triggers the increase in calcium necessary to enhance the effects of the serotonin released by the interneuron in response to the ucs.
