Question 1

Alex a was at a party and by the time she got home, she could not walk in a straight line. You know that she took a drug that suppressed the activity in her cerebellum. What was the drug?

Accepted Answer

Alcohol is known to suppress the activity in the cerebellum, which can lead to difficulty in walking in a straight line, among other motor control issues.

Question 2

Rafiel was at a party and drank a lot of alcohol. He had trouble walking in a straight line. Most likely, this is because the alcohol affected his

Accepted Answer

Alcohol affects the cerebellum, which is responsible for coordination and balance, leading to difficulty in walking straight.

Question 3

Joan contracted viral encephalitis. As a result, there was damage to her hippocampus. This is most likely to affect her

Accepted Answer

The hippocampus is primarily associated with memory, especially in the formation of new memories and the connection of emotions and senses, such as smells and sounds, to these memories. Damage to the hippocampus typically results in difficulties in forming new memories and may affect the ability to recall recent events.

Question 4

in order to get information about brain function, which of he following scans should you use?

Accepted Answer

PET scans and fMRIs are both used to study brain function. PET scans measure metabolic processes by detecting radiation from the emission of positrons, while fMRIs focus on changes in blood flow related to neural activity, offering insights into brain function.

Question 5

In order to speak properly, there are at least two areas of the brain that need to be functioning. If you could move your tongue and lips and sequence the words properly, but not really comprehend, the damage would be most likely in

Accepted Answer

Wernicke's area is responsible for the comprehension of speech. Damage to this area can result in the ability to produce fluent speech without understanding the meaning, indicating a comprehension issue.

Question 6

In order to speak properly, there are at least two areas of the brain that need to be functioning. If you could move your tongue and lips but not sequence the words properly, the damage would be most likely in

Accepted Answer

Broca's area is responsible for speech production, so damage to this area would result in difficulty sequencing words properly.

Question 7

As you are driving, another car pulls out unexpectedly from a side road. You find that your heart rate increases and you are breathing faster. This is because of activation in the

Accepted Answer

The sympathetic nervous system is responsible for the "fight or flight" response, which includes increasing heart rate and breathing rate in response to stress or danger, such as another car pulling out unexpectedly.

Question 8

You are observing a patient who seems to have a psychological disorder. The patient's history indicates a dysfunction in the mirror neuron system. What kind of disorder does the patient have?

Accepted Answer

Dysfunction in the mirror neuron system is often associated with Autism Spectrum Disorder, as it may affect social cognition and the ability to understand others' actions and intentions.

Question 9

Isaac contracted viral encephalitis. Five days later, he was unable to remember a number of details about his life and had trouble acquiring new memories. Most likely, the virus had damaged his

Accepted Answer

The hippocampus is crucial for memory formation and retrieval. Damage to this area, such as from viral encephalitis, can lead to difficulties in forming new memories and recalling personal information, which matches Isaac's symptoms.

Question 10

Let's say that you are a medical doctor. One of your patients seems to be suffering from an under supply of serotonin. What disorder would you suspect that his patient has?

Accepted Answer

Depression is commonly associated with an imbalance or undersupply of serotonin in the brain, which is a key neurotransmitter involved in mood regulation.

Question 11

Steve has aphasia. He can talk, but his communication is telegraphic-he has difficulty stringing words together in a sentence. Most likely, Steve has damage to an area in the

Accepted Answer

The frontal lobe, specifically the Broca's area located in the frontal lobe, is associated with speech production and language comprehension. Damage to this area can result in aphasia, where individuals may have difficulty forming complete sentences, leading to telegraphic speech.

Question 12

Joel was in a car accident and banged his head. When the ambulance arrived at the hospital, he was unable to see. Most likely, Joel hit

Accepted Answer

The occipital lobe, located at the back of the head, is responsible for vision. Damage to this area can result in visual impairment or blindness.

Question 13

Joel was in a car accident and banged his head. When the ambulance arrived at the hospital, he was unable to hear. Most likely, Joel hit an area on

Accepted Answer

The temporal lobe is responsible for processing auditory information, so damage to this area can result in hearing loss.

Question 14

You are trying to get a good scan of a patient's brain in order to see where the area of greatest activity is. Which of the following would be the worst scan to use?

Accepted Answer

EEG (Electroencephalography) measures electrical activity in the brain and is not ideal for visualizing the structure of the brain or pinpointing areas of activity with high spatial resolution. It is more suited for assessing brain wave patterns over time. In contrast, PET, MRI, CAT, and fMRI scans are better suited for detailed imaging of brain structure and function, making them more appropriate for identifying specific areas of brain activity.

Question 15

Your friend has had serious brain injury and the doctors want to know if certain areas are still functioning. Which of the following scans would be the best to use for this purpose

Accepted Answer

Functional Magnetic Resonance Imaging (fMRI) is the best choice for assessing brain function because it measures brain activity by detecting changes associated with blood flow. This allows doctors to see which areas of the brain are active during specific tasks or in response to stimuli, providing valuable information about the functioning of different brain regions following injury.

Question 16

Joel was in a car accident and banged his head. When the ambulance arrived at the hospital, he was unable to speak. Most likely, Joel hit an area

Accepted Answer

The inability to speak, often resulting from damage, is most commonly associated with the frontal lobe, specifically the Broca's area located in the frontal lobe, which is responsible for speech production.

Question 17

In order to speak properly, there are at least two areas of the brain that need to be functioning. If you could not move your tongue and lips at all, the damage would be most likely in

Accepted Answer

The motor cortex is responsible for controlling voluntary movements, including those necessary for speech such as moving the tongue and lips. Damage to this area would impair the ability to perform these movements.

Question 18

You would like to get some information about how a particular brain area functions. But you cannot destroy the area or stimulate the area and you do not want to work with a patient who has brain damage. Which of the following would be best to use?

Accepted Answer

The answer of You would like to get some information...

Question 19

You are trying to get a good scan of a patient's brain in order to see where the area of greatest activity is. Which of the following would be the best scan to use?

Accepted Answer

fMRI (functional Magnetic Resonance Imaging) is the best choice for measuring brain activity as it can show the areas of the brain that are most active by detecting changes in blood flow.

Question 20

A new treatment for Parkinson's disease has the side effect of blocking dopamine action in the nucleus accumbens. For a patient on this drug, which of the following would likely be diminished?

Accepted Answer

The nucleus accumbens is part of the brain's reward circuit and is heavily involved in the dopamine-mediated reward system. Blocking dopamine action in this area would likely diminish the sense of reward.
