Homework due 4/7/09 Name _____________________________________ 1. Why do we need an animal model for human long-term relational memories? What is the most studied animal model for studying relational long-term memories? Describe the rat's task in this model. How good are rats at this task? What is the relational memory that the rat must store to perform normally. 2. What does LTP stand for? How is it experimentally induced (what electrodes are used and where are they placed)? Can it be done in vivo or in vitro? How would you do it in vitro? 3. What is the difference between the evoked potential before and after LTP? What change in the pattern of neuronal firing causes this difference (hint: draw on information that you’ve learned about EEG’s)? 4. What happens to glutamic acid synapses in the hippocampus after LTP that accounts for the extracellular spike that serves as evidence of LTP. 5.
