Question 1

Which of the following would be most useful for measuring electronic neuronal transmission in the brain?
A)EEG
B)MRI
C)PET
D)CT

Accepted Answer

EEG (electroencephalography)measures the electronic neuronal transmission in the brain with the use of noninvasive scalp electrodes.

Question 2

Which of the following imaging techniques would be most effective for identifying subcellular brain pathology?
A)CT
B)MRI
C)PET
D)X-ray

Accepted Answer

PET scanning allows for regional three-dimensional quantification of glucose and oxygen metabolism or blood flow in the human brain for the detection of subcellular brain pathology.

Question 3

Lesions in Wernicke's area cause a(n):
A)motor aphasia
B)sensory aphasia
C)agnosia
D)apraxia

Accepted Answer

Wernicke's area is responsible for speech recognition;therefore a lesion in this area results in a sensory aphasia.

Question 4

Which of the following is NOT true of CT scans?
A)CT scans involve passing an x-ray beam through the brain.
B)CT scans provide a two-dimensional view of three-dimensional objects.
C)CT scan images are sometimes enhanced by use of a contrast substance.
D)CT scans allow for the calculation of the density of tissue in a particular cross-section of the brain.

Accepted Answer

CT scans provide a three-dimensional view,which is one of its primary advantages over x-rays,which provide a two-dimensional view of three-dimensional objects.

Question 5

Lesions in Broca's area cause a(n):
A)motor aphasia
B)sensory aphasia
C)agnosia
D)apraxia

Accepted Answer

Broca's area is an expressive speech center,and therefore a lesion in this area of the brain leads to a motor aphasia.

Question 6

The term cephalic can be used in place of which anatomical directional term? A)superior B)ventral C)dorsal D)inferior

Accepted Answer

Cephalic refers to the upper region and is therefore interchangeable with the term superior.

Question 7

Which of the following is true of the clinicopathologic method in neurology?
A)It is the method of establishing a link between the site of a lesion and the function that is lost or modified.
B)It is the method of using modern imaging techniques to determine the site of a brain lesion.
C)It is rarely applied in practical neurologic diagnosis.
D)It applies only to lesions in Wernicke's area.

Accepted Answer

The clinicopathologic method is defined as the method of establishing a link between the site of a lesion and the function that is lost or modified.

Question 8

Which of the following is NOT true of MRI imaging?
A)MRI imaging utilizes radio waves.
B)MRI imaging provides an excellent computer-generated pictorial image of the brain.
C)MRI imaging uses a strong magnetic field to determine the distribution of water molecules in living tissue.
D)MRI is a much more cost-effective technique than CT imaging.

Accepted Answer

MRI images are more expensive to generate than CT images.

Question 9

A dysarthria is:
A)a disorder of cortical sensory recognition
B)a disorder of executing motor acts as a result of a brain lesion
C)a group of fibers connecting areas or centers of the brain
D)a neurologic speech disorder

Accepted Answer

This is the definition of dysarthria.

Question 10

Structures lying at the base of the brain may be anatomically described as being:
A)dorsal
B)rostral
C)cephalic
D)ventral

Accepted Answer

Ventral (toward the front)is also sometimes used to describe structures at the base of the brain.

Question 11

A PET scan measures what type of brain activity?
A)electronic neural transmission
B)glucose metabolism
C)brain waves
D)the flow of cerebrospinal fluid

Accepted Answer

PET scans use radioactively labeled glucose to measure metabolic activity in the brain.

Question 12

In neurology,the concept of localization of function refers to: A)the fact that the left hemisphere of the brain contains the language center as identified by Broca B)the fact that specific behavioral functions appear to be associated with clearly localized sites within the brain C)the fact that each organ of the body contributes in its own unique way to the function of the whole D)the fact that the two hemispheres of the brain are symmetric in their function

Accepted Answer

Localization of function in neurology refers to the idea that specific behavioral functions are associated with specific locations within the brain. This concept has been supported by numerous studies and observations, such as Broca's and Wernicke's areas being associated with language processing in the left hemisphere of the brain. Option A is partially correct but does not encompass the full idea of localization of function. Option C is incorrect as it refers to the concept of organ contribution rather than brain function. Option D is incorrect as the two hemispheres of the brain are not necessarily symmetric in their function.
