Activity 7: • Compare the conduction velocities of the three neurons. Based on what we discussed in class, why did you notice these changes? Activity 8: • When the “Control Ca2+” solution was used, why do you suppose more neurotransmitter was released when going from a low intensity stimulus to a high intensity stimulus? • Why was there no release of neurotransmitters when the “No Ca2+” solution was used? Why did this occur? • How did the amount of neurotransmitters secreted in the “Low Ca2+” compare to the amount secreted in the “Control Ca2+”? Why do you think this occurred? • Why did the “Mg2+” solution affect the amount of neurotransmitters released?

Consider the field experiment with politicians that we discussed in the lecture. The experiment is based on a modified dictator game. In Treatment 1 (i.e. T1), nature plays with high probability (equal to 0.8) and randomly assigns the endowment either to the politician-dictator or to the recipient. The politician--dictator plays with complementary probability (and knows, when making a decision, that this decision will be implemented); in contrast, a recipient who receives zero (or the full endowment), will not know whether...

1. we discussed the variation among several species of (based on the geological dates we have covered) recent human species that do NOT include neanderthals. I would like for you to identify two, and write three to four bullet points to identify characteristics of each. 2. Next, tell me a bit about Neanderthals, and why they are more intelligent and social than stereotypes that exist in popular culture (think Geico commercials, cavemen, etc).
