This exam has a total of 13 points. Each point corresponds to a numbered question. The numbered question is to be answered. The correct answer to a numbered question will give you one point. If the answer is partially correct, partial credit will be given as a decimal value. If the answer is incorrect, no credit will be given. If the question is unanswered, no credit will be given so it is better to guess than to leave a question blank. The number of points earned will be divided by the total number of points on the exam and multiplied by 100 to get your grade. Good luck!

1. In the background section the authors wrote â€œSince the mice had body weights of ~25 g, the corresponding ratios of isoflurane concentration to mouse body weight were 0.004%/g, 0.006%/g, 0.008%/g, 0.01%/g, 0.012%/g, 0.014%/g, 0.016%/g, 0.018%/g, 0.020%/g, 0.022%/g and 0.024%/g, respectively.â€ How were these ratios calculated? (1 point)

1. How did the authors deal with the effects of anesthetic from one animal to the next? (1 point)

1. Quote something from the article as evidence that your answer to question 2 is correct. (1 point)

1. In the results section the authors wrote, â€œThe results indicate that the success rate decreases step-wise as the ratio of isoflurane concentration to mouse body weight increases.â€ What kind of correlation is this? Positive, negative, or no correlation? (1 point)

1. How do you know that your answer to question 4 is correct? (1 point)

1. What does isoflurane concentration to mouse body weight mean for body weight? (1 point)

1. Why did you give the answer that you gave for question 6? (1 point)

1. In the results section the authors wrote Then, as the ratio continued to increase to 0.020%/g, the delay time value increased rapidly and finally stabilized at approximately 120 ms (0.018%/g: 113.2 Â± 13.3 ms, 0.020%/g: 119.5 Â± 12.9 ms) (N = 11, mean Â± S.D., paired t-test, *p < 0.05, df = 10, t values shown in Table 1). What kind of correlation is this? Positive, negative, or no correlation? (1 point)

1. How do you know that your answer to question 8 is correct? (1 point)

1. In the results section the authors wrote â€œThe results indicate that the anesthetic does significantly influences the success rate and the EMG latency, duration and normalized amplitude induced by LIPUS.â€ What kind of correlation is this? Positive, negative, or no correlation? (1 point)

1. How do you know that your answer to question 10 is correct? (1 point)

1. What kind of correlation was the normalized amplitude of the EMG? Positive, negative, or no correlation? (1 point)

1. How do you know that your answer to question 12 is correct? (1 point)
