Test 3 Flashcards
True or false: A low-frequency tone will cause the base of the basilar membrane to vibrate.
False
True or false: When we use intensity differences to localize sound, we are basing our decision on the difference in the time it takes soundwaves to reach one ear as compared to the other.
False
If someone had problems generating/secreting enough insulin, which of the following would be MOST likely to happen?
The person would have problems storing ‘blood sugar’ for future use
True or false: To change the volume of a sound, we must change the height of the sound waves
True

True
Imagine you are sitting in the library. All of a sudden someone decides to host an impromptu death metal rock concert at the table next to the one you are sitting at. Which of the following help protect your ears from damage from the noise (select all that apply):
Stapedius
If a doctor wanted to measure only muscle activity in a patient, which of the following would they use (select all that apply)?
EMG
True or false: Brain waves in REM are small and ‘jagged’ because the neural activity of the brain becomes synchronized.
Brain wave activity during REM is small/jagged. However, brain activity in REM is NOT synchronized. Synchronized neural activity results in large, slow brain waves (such as those seen in SWS).
Which of the following are parts of the middle ear
Malleus and Ossicles
True or false: Immediately after you fall asleep, you are MORE likely to be in SWS?
True
Your sister’s dog, Samantha, has narcolepsy. Given this information, which of the following is true?
Samantha’s disorder is caused by a mutant gene that affects her hypocretin neurons
Which of the following IS NOT evidence that long-term potentiation (LTP) is involved in memory?
LTP has not been observed in the brain and LTP occurs only in mice, rats and sea slugs
If all the voltage-dependent Ca2+ channels in the auditory hair cells of our ear stopped working, which of the following is true about what would happen (select all that apply):
Glutamate would not be released from hand cell
Which of the following is an example of a Hebbian Synapse?
Two neurons being activated at the same time
Based only on what we learned in class about the hormones and chemicals that control eating, if your body stopped making and releasing leptin, which of the following would be most likely to happen:
You would no longer be able to experience feeling satiated (‘full’)
