Question 1

Which of the following best describes the function of the somatic nervous system?

Accepted Answer

Question 2

A patient suffers damage to the corpus callosum. Which of the following is the most likely result?

Accepted Answer

Disrupted communication between the left and right cerebral hemispheres.

Question 3

Which brain imaging technique is best suited for measuring the structure (shape and size) of the brain?

Accepted Answer

Magnetic Resonance Imaging (MRI)

Question 4

Which of the following statements about the central nervous system (CNS) is correct?

Accepted Answer

The CNS consists of the brain and spinal cord.

Question 5

A researcher wants to study rapid changes in brain activity in response to a specific event. Which imaging technique should they use?

Accepted Answer

Electroencephalogram (EEG)

Question 6

Which of the following is a function of the parasympathetic division of the autonomic nervous system?

Accepted Answer

Conserving body resources and maintaining body functions.

Question 7

Which structure is responsible for connecting the brain and the peripheral nervous system?

Accepted Answer

Spinal cord

Question 8

A neuroscientist is interested in the white matter tracts of the brain. Which imaging technique should they use?

Accepted Answer

Diffusion Tensor Imaging (DTI)

Question 9

Which of the following best describes the function of the thalamus?

Accepted Answer

It acts as a relay station, interpreting and transmitting sensory information to the cortex.

Question 10

Which of the following is a key difference between EEG and fMRI?

Accepted Answer

EEG has high temporal resolution but poor spatial resolution, while fMRI has good spatial resolution but lower temporal resolution.

Question 11

A patient is unable to coordinate voluntary movements and maintain balance. Which brain structure is most likely affected?

Accepted Answer

Cerebellum

Question 12

Which of the following best describes the function of the reticular formation?

Accepted Answer

Regulating arousal and alertness.

Question 13

Which of the following is true about gyri and sulci in the cerebral cortex?

Accepted Answer

Gyri are the ridges and sulci are the grooves on the surface of the cortex.

Question 14

Which equation best represents the relationship between the spatial and temporal resolution of brain imaging techniques?

Accepted Answer

$$Resolution_{total} = f(Resolution_{spatial}, Resolution_{temporal})$$

Question 15

A psychologist is interested in the brain's response to a specific stimulus over time. Which method should they use to measure event-related changes?

Accepted Answer

Event-Related Potentials (ERPs)

Question 16

Which of the following is a primary function of the spinal cord?

Accepted Answer

Acting as a pathway connecting the brain and the peripheral nervous system.

Question 17

Which of the following best describes the function of the autonomic nervous system?

Accepted Answer

It regulates involuntary body functions such as heart rate and digestion.

Question 18

Which imaging technique is most appropriate for studying the time course of neural activation in response to a stimulus?

Accepted Answer

Electroencephalogram (EEG)

Question 19

Which of the following is a key advantage of using fMRI over EEG?

Accepted Answer

fMRI provides better spatial resolution.

Question 20

A patient with damage to the gray matter of the cerebral cortex is most likely to experience which of the following?

Accepted Answer

Impairments in processing and integrating information.
