1. Which technology is primarily used to measure sleep stages?
EEG
Ultrasound
MRI
CT scan
2. Which glial cells guide migrating neurons?
Correct answer
3. Describe the role of the prefrontal cortex in cognitive functions such as
decision-making and planning.
The prefrontal cortex processes visual information and is
responsible for sight.
The prefrontal cortex is primarily responsible for processing
auditory information.
The prefrontal cortex regulates basic survival functions like
breathing and heart rate.
The prefrontal cortex is involved in higher-order cognitive
functions, including planning, decision-making, and evaluating
consequences.
4. What is one example of a cognitive symptom in schizophrenia?
Hallucinations

Problem with attention and memory
Lack of desire to form social relationships
Believing other people are controlling one's thoughts
5. It inhibits a habitual action when it is inappropriate.
Posterior parietal cortex
Premotor cortex
Prefrontal cortex
Supplementary motor cortex
6. If a patient has damage to the primary somatosensory cortex, what
sensory function is likely to be impaired?
The ability to control voluntary movements
The ability to accurately perceive touch sensations
The ability to recognize faces
The ability to process auditory information
7. If a person has a condition that affects the function of bipolar cells in the
retina, what visual impairments might they experience?
Enhanced night vision
Inability to perceive motion
Complete blindness
Difficulty in detecting colors and fine visual details
8. Describe how the primary somatosensory cortex contributes to our
perception of touch.
,5/14/25, 11:13 PM D574 Neuropsychology Practice Test
The primary somatosensory cortex is involved in the production
of speech and language.
The primary somatosensory cortex processes and maps sensory
information from various body regions, allowing us to perceive
touch accurately.
The primary somatosensory cortex is responsible for regulating
heart rate and blood pressure.
The primary somatosensory cortex integrates visual and auditory
information for comprehensive perception.
9. What is the term for the type of memory involved in performing tasks like
playing an instrument or driving a car?
Procedural memory
Sensory memory
Declarative memory
Working memory
10. In a study examining the effects of traumatic brain injury, researchers
found increased activity of certain glial cells. Which glial cells are likely
being referenced, and what is their function in this context?
Microglia; they are activated to remove damaged cells and
debris after injury.
Astrocytes; they provide structural support to neurons during
recovery.
Oligodendrocytes; they regenerate myelin sheaths after injury.
Ependymal cells; they produce cerebrospinal fluid to cushion the
brain.
11. This gland is often referred to as the "master gland" because it coordinates
the control of all other glands in the endocrine system.
, 5/14/25, 11:13 PM D574 Neuropsychology Practice Test
Thyroid
Hypothalamus
Gonads
Adrenal
Pituitary
12. If a drug were to enhance dopamine release in the nucleus accumbens,
what potential behavioral changes might be observed in an individual?
Reduced sensory perception
Impaired motor coordination
Decreased cognitive function and memory
Increased motivation and pleasure-seeking behavior
13. The division of the autonomic nervous system that has functions involved
in energy conservation and "vegetative" functions is
Autonomic
Parasympathetic
Somatic
Sympathetic
14. Which technique depends upon oxygen levels in hemoglobin molecules?
rCBF
PET
MRI
fMRI
15. Describe how fMRI contributes to our understanding of brain activity.
