Question 1

Which neuroimaging approach involves measuring changes in magnetic field properties due to oxygenated versus deoxygenated blood?&#10;A)Functional magnetic resonance imaging&#10;B)Computerized axial tomography&#10;C)Positive emission tomography&#10;D)Electroencephalogram

Accepted Answer

Functional magnetic resonance imaging (fMRI) measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. The primary form of fMRI uses the blood-oxygen-level-dependent (BOLD) contrast, which is a type of signal that depends on the properties of oxygenated versus deoxygenated blood, making it the correct choice for the question.

Question 2

The proportion of the variability in psychological symptoms or traits that can be attributed to genetic variability refers to:&#10;A)Heritability&#10;B)Relatedness&#10;C)Nurture&#10;D)Nature

Accepted Answer

Heritability is the correct term for the proportion of variability in traits, including psychological ones, that can be attributed to genetic differences among individuals. It quantifies how much of the variation in a trait across a population is due to genetic differences.

Question 3

This neurotransmitter is especially involved in reward and reinforcement, motor function, and cognition and attention.&#10;A)Glutamate&#10;B)Acetylcholine&#10;C)Epinephrine&#10;D)Dopamine&#10;E) Serotonin

Accepted Answer

Dopamine plays a key role in the brain's reward system, influencing motivation and pleasure. It also has significant roles in motor control, cognition, and attention, making it crucial for both physical movements and cognitive processes.

Question 4

This neurotransmitter is involved in attention and memory.&#10;A)Glutamate&#10;B)Serotonin&#10;C)Epinephrine&#10;D)Dopamine&#10;E) Acetylcholine

Accepted Answer

Acetylcholine is a neurotransmitter that plays a crucial role in attention and memory processes.

Question 5

Which neuroimaging approach involves radioactively labeled substances being introduced into the bloodstream, where they are taken up into the brain?&#10;A)Functional magnetic resonance imaging&#10;B)Computerized axial tomography&#10;C)Positive emission tomography&#10;D)Electroencephalogram

Accepted Answer

Positive emission tomography (PET) involves the use of radioactively labeled substances that are introduced into the bloodstream and then taken up by the brain, allowing for the visualization of brain activity.

Question 6

Which part of the brain is important in emotion processing?&#10;A)Left hemisphere&#10;B)Right hemisphere

Accepted Answer

The right hemisphere of the brain is particularly important in processing emotions. It plays a significant role in interpreting emotional content and expressions, as well as in emotional regulation.

Question 7

This neurotransmitter is associated with behavioral and emotional regulation.&#10;A)Epinephrine&#10;B)Dopamine&#10;C)Glutamate&#10;D)Serotonin&#10;E) Acetylcholine

Accepted Answer

The answer of This neurotransmitter is associated with behavioral and...

Question 8

This neurotransmitter is is the primary excitatory neurotransmitter in the adult brain&#10;A)Glutamate&#10;B)Serotonin&#10;C)Epinephrine&#10;D)Dopamine&#10;E) Acetylcholine

Accepted Answer

Glutamate is recognized as the primary excitatory neurotransmitter in the adult brain, playing a key role in brain functions such as learning and memory.

Question 9

This neurotransmitter is involved in the &#34;flight or fight&#34; response.&#10;A)Acetylcholine&#10;B)Serotonin&#10;C)Epinephrine&#10;D)Dopamine&#10;E) Glutamate

Accepted Answer

Epinephrine, also known as adrenaline, is a key neurotransmitter and hormone involved in the "fight or flight" response, which prepares the body to respond to a perceived threat.
