Unformatted text preview: Last Set of Krasne Study Questions 1. NOT COVERED If a neuron that starts with equal amounts of sodium (+) and chloride (-) ions outside and the same amounts of potassium (+) and A- ions inside, what will happen if the cell becomes permeable to chloride?. a. nothing b. it will become negative inside c. it will become positive inside 2. Suppose one pinched a retinal ganglion cell so hard that it fired madly and then died. The most likely sensation of the individual would probably be one of a. light or shadow b. touch and pain c. both a and b. 4. Learning of the finger-tapping task used in the experiments showing a need for sleep-produced consolidation and re- consolidation was probably due to a. synaptic changes in the hippocampus b. synaptic changes in the basal ganglia and cortex 5. Suppose one made a mouse whose gene for making CREB2 were knocked out (i.e. made non-functional) a. this mouse probably would not be able to learn b. this mouse would probably learn normally but not be able to remember for more than a few hours c. this mouse would probably learn easily and remember well with less training than a normal mouse 6. Suppose a cell had more CREB1 than CREB2 and following each learning experience CREB1 remained tagged less long than CREB2. Then, according to the logic of the fellow who did the experiments on fruit flies, for a given number of training trials, a. massed training would probably produce more long-term memory than spaced training b. spaced training would probably produce more long-term memory than massed training c. spaced and massed training might not be much different in the amount of long-term memory they produced.c....
