Question 1 Which mechanism below could explain why executive function is impaired during high-intensity exercise? Increased attention as a result of norepinephrine release in the cortex Transient hypofrontality Decreased blood flow to the working muscles I wish my executive function wasn't impaired right now Increased reaction time Question 2 According to the Yerkes-Dodson law... Acute exercise of very high intensity will have the greatest benefit to cognitive function Acute exercise of very low intensity will have the greatest benefit to cognitive function Acute exercise of moderate intensity will have the greatest benefit to cognitive function Acute exercise will not impact cognitive function 0.5 pts 0.5 pts Question 3 Sleep maintenance insomnia is characterized by A) Frequent periods of waking during the night (sleep fragmentation) B) Early waking without going back to sleep C) Trouble falling asleep (increased sleep onset latency) F) A, B, and C are all correct E) A and B only Question 4 Which factor(s) contribute to the enhancement of cognitive function in rats that exercise? F) A, B, and C only D) Placebo effect E) A, B, C, and D are all correct B and C only O Brain-derived neurotrophic factor (BDNF) B) Adult hippocampal neurogenesis A) Acetylcholine 0.5 pts 0.5 pts > Question 5 Describe how you would know if exercise improved learning and memory in rats. Hint: remember the two animal models of memory discussed in the lectures. Question 6 0.5 pts Which glutamate receptor critical for LTP has a calcium (Ca2+) channel that is typically blocked by magnesium (Mg2+)? NMDA receptor NE receptor MDMA receptor AMPA receptor Question 7 What are 2 indirect and 2 direct mechanisms by which exercise could benefit sleep?

Question 9 0.5 pts Describe the 3 phases of LTP and include at least 2 post-synaptic and 2 pre-synaptic proteins involved.
