Your answers are highlighted below.

Question 1

How big is the cerebellum in relation to the cerebrum?

	It is smaller.
	It is bigger. Hint: Are you sure? Come on, take one more guess. I know you can do this.
	It is of the same size. Hint: Um, I guess not. I know you know what’s right.
	It is the biggest. Hint: Please, try again. I know you'll get it this time.

Question 1 Explanation:

Exactly! The cerebullum is Latin for “little brain.” More of this can be seen in this video.

Question 2

When an individual lacks the ability to coordinate his/her writing (or any movement for that matter) with what he/she sees and thinks, there is most probably a damage to what part of his/her brain?

	cerebellum
	brain stem Hint: Nope. A part of the brain stem is responsible for motor control and sensory analysis. What we are looking for is responsible for coordination of movement. Go on and pick another one :)
	thalamus Hint: The thalamus also takes in sensory input but works more of like a regulatory gateway that kind of regulates what comes in and what goes out. Please, try again!
	hypothalamus Hint: Oh, no! You need to make another guess. The hypothalamus is involved in functions including homeostasis, emotion, thirst, hunger, circadian rhythms, and control of the autonomic nervous system

Question 2 Explanation:

You got it right! The cerebullum is that part of the brain that coordinates movement. It takes sensory input and coordinates movement based from that input. More of this is illustrated and clearly explained in this video.

Question 3

Sometimes, when we get hit right at the back of the head, we start to see stars. Which part of the brain is affected when this happens?

	The occipital lobe of the cerebrum.
	cerebellum Hint: You’re probably just confused. Try again :)
	brain stem Hint: The brain stem is responsible for a number of processes such as vision, hearing, eye movement, and body movement. What we are looking for is located at the back of the head. Get it?
	The frontal lobe of the cerebrum. Hint: Try the lobe found at the opposite side of the head.

Question 3 Explanation:

Oh you are good! The occipital lobe is a part of the cerebrum involved in visual processing. If you want to learn more about the different parts of the cerebrum and its functions, you can see the video here.

Question 4

Which of the following is NOT a part of the brain stem?

	thalamus
	medulla Hint: Oh, this is definitely a part of the brain stem. Please try again.
	pons Hint: No, please try another one. I know you’ll get this.
	midbrain Hint: This is part of the brain. You’ve got to think a little harder :)

Question 4 Explanation:

Perfect! The brain stem consists of only the midbrain, medulla, and pons. You can learn more about the brain stem and its parts by watching this video.

Question 5

Which two parts of the brain are responsible for controlling/regulating autonomic processes ?

	medulla and the hypothalamus
	medulla and midbrain Hint: You got one of the pairs, right. Please try again. I know you’ll get it right this time.
	hypothalamus and thalamus Hint: You got one of the pairs, right.. Please pick another one.
	medulla and thalamus Hint: Hmmm. One of the pairs is right but you need to change the other one in the pair.

Question 5 Explanation:

Oh, wow! I knew this wouldn’t be so hard. The medulla controls vital functions such as breathing, heart rate, and blood pressure. The hypothalamus is involved in functions including homeostasis, emotion, thirst, hunger, circadian rhythms, and control of the autonomic nervous system. More about the medulla can be seen here and about the hypothalamus, here.

Question 6

What part of the brain stem is responsible for motor control and sensory analysis?

	pons
	midbrain Hint: The midbrain is located in the same location as that part that we are looking for. What part is then responsible for motor control and sensory analysis?
	medulla Hint: This is mainly responsible for some maintaining vital body functions, such as breathing and heart rate.
	thalamus Hint: Not this one, though. The thalamus works like a regulatory gateway for sensory inputs coming in and out of it.

Question 6 Explanation:

Wow! You got a good memory. The pons is a part of the brain stem and is involved in motor control and sensory analysis. More of the cerebrum, it’s parts and functions can be found here.

Question 7

Usually, intelligent persons are said to have larger _________ in that they are excellent problem solvers, and are usually excellent in reasoning and planning.

	frontal lobe
	parietal lobe Hint: You got it all mixed up.Come on I know you can do this.
	occipital lobe Hint: Try something located somewhere on the opposite side of the brain.
	temporal lobe Hint: The temporal lobe deals with auditory perception, memory, and speech. Please try again.

Question 7 Explanation:

I bet you have a big frontal lobe, too huh. Good job! To read more about this, you can refer to this video and learn more.

Question 8

In which special region of the thalamus are signals from the ganglion cells in the retina sent to for processing?

	lateral geniculate
	medial geniculate Hint: Not really. Try a different location. I think I know you’ll get it this time.
	gustatory territory Hint: No, you’ll have to try another one. The gustatory territory is related to our sense of taste.
	super geniculate Hint: Hmmm. I don’t think there exist this part in the thalamus. Try again, I know you’re just a bit confused.

Question 8 Explanation:

This is the special region where the signals are sent to. The thalamus works as a regulatory gateway for almost all sensory input and then the motor output goes via the thalamus to the rest of your body. For more information about the thalamus, you can refer to this video.

Question 9

If the occipital lobe of the cerebrum is involved in visual processing,which lobe deals with auditory perception, memory, and speech?

	temporal lobe
	parietal lobe Hint: I know you’ll get it this time. Please try again.
	frontal lobe Hint: Not really. You have to make another guess. I know you know this.
	also occipital lobe Hint: Oh, no. Please try again

Question 9 Explanation:

You must be really good! The cerebrum has four lobes and among these, the temporal lobe deals with auditory perception, memory, and speech. For more on the cerebrum, you can review the video here.

Question 10

Which of the following would the medulla be involved with?

	heart rate
	running Hint: The medulla is involved in autonomic processes. That’s quite big hint. I know you’ll get it this time.
	putting food in your mouth Hint: No, please try again. Among the choices, which is different?
	speaking Hint: The medulla has nothing to do with what you speak. Pick another one.

Question 10 Explanation:

Great job! The medulla is actually involved in maintaining vital body functions as mentioned in Episode 027, and heart rate is one of them.. You can always review the topic in this video.
