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?
