Question 1

A patient shaves only one side of his face, reads only half of compound words, and dresses and uses only half of his body. Collectively, this patient is exhibiting symptoms of _____.&#10;A) topographic disability&#10;B) anosagnosia&#10;C) constructional apraxia&#10;D) contralateral neglect

Accepted Answer

The patient is exhibiting symptoms of contralateral neglect, where the patient is unaware of one side of their body and neglects that side in daily activities. This is demonstrated by the patient shaving only one side of his face, reading only half of compound words, and dressing and using only half of his body. Topographic disability is a difficulty in recognizing familiar surroundings, anosagnosia is a lack of awareness or insight into one's own condition, and constructional apraxia is difficulty in constructing or copying simple designs. None of these fully describe the patient's symptoms.

Question 2

The close anatomical relationship between the parietal lobe and the prefrontal cortex is thought to be related to _____.&#10;A) the elaboration of motor programs&#10;B) grammatical constructions&#10;C) spatially guided behavior&#10;D) dissociation

Accepted Answer

The parietal lobe and prefrontal cortex work together to enable spatially guided behavior, such as navigating and interacting with our environment.

Question 3

The task to test for simultaneous extinction presents:&#10;A) visual stimuli to the right visual field.&#10;B) tactile stimuli one at a time to the right hand.&#10;C) two tactile stimuli simultaneously, one to each hand.&#10;D) two visual stimuli simultaneously, both in the right visual field.

Accepted Answer

The task to test for simultaneous extinction involves presenting two tactile stimuli simultaneously, one to each hand, to assess the individual's ability to perceive both stimuli at the same time. This is used to detect neurological impairments, particularly in the context of spatial neglect or sensory deficits.

Question 4

The _____ is used to test for apraxia.&#10;A) Kimura Box Test&#10;B) two-point discrimination test&#10;C) Seguin-Goddard Form Board test&#10;D) Token Test&#10;Answer Key

Accepted Answer

The Kimura Box Test is specifically designed to evaluate apraxia, which is a neurological condition that affects a person's ability to carry out purposeful movements. This test involves patients using their hands to manipulate objects in a wooden box under timed conditions. Patients with apraxia may take longer, make mistakes, or have difficulty completing the task compared to those without apraxia.

Question 5

In Brodmann's mapping system, areas 5 and 7 correspond to von Economo's area _____.&#10;A) PE&#10;B) PF&#10;C) PG&#10;D) PH

Accepted Answer

Brodmann areas 5 and 7 correspond to von Economo's area PE, which is involved in somatosensory processing and spatial orientation.

Question 6

The inability to recognize objects by touch is called _____.&#10;A) afferent paresis&#10;B) simultaneous extinction&#10;C) blind touch&#10;D) astereognosis

Accepted Answer

Astereognosis is the inability to recognize objects by touch.

Question 7

Contralateral neglect is commonly found after damage to _____.&#10;A) areas PE and PG in the left hemisphere&#10;B) area PG in the right hemisphere&#10;C) area PE&#10;D) areas PE and PF

Accepted Answer

Contralateral neglect is commonly found after damage to area PG in the right hemisphere. This area is responsible for integrating sensory information from both sides of the body, and damage to it can lead to the neglect of the opposite side of the body. Damage to areas PE and PG in the left hemisphere or to areas PE and PF would not typically result in contralateral neglect.

Question 8

Apraxia is commonly found after damage to _____.&#10;A) area PE&#10;B) areas PF and PG in the left hemisphere&#10;C) the cingulate gyrus&#10;D) area PG in the right hemisphere

Accepted Answer

Areas PF and PG in the left hemisphere are responsible for motor planning and coordination, and damage to these areas can result in apraxia.

Question 9

Which is more likely after right parietal damage?&#10;A) more errors in Weigl's Sorting Test&#10;B) Wernicke's aphasia&#10;C) dressing disability&#10;D) dyscalculia

Accepted Answer

Right parietal damage often leads to difficulties with spatial awareness and coordination, which can manifest as a dressing disability, where the individual struggles with organizing and putting on clothes properly.

Question 10

Which is NOT one of the classic symptoms of Gerstmann syndrome?&#10;A) finger agnosia&#10;B) apraxia&#10;C) agraphia&#10;D) acalculia

Accepted Answer

The classic symptoms of Gerstmann syndrome are finger agnosia (inability to distinguish fingers), agraphia (inability to write), acalculia (inability to perform simple arithmetic calculations), and left-right confusion. Apraxia, which is difficulty carrying out voluntary movements despite intact motor function, is not one of the classic symptoms of Gerstmann syndrome.

Question 11

The lateral aspect of the parietal lobe is demarcated ventrally by the _____.&#10;A) central fissure&#10;B) cingulate gyrus&#10;C) Sylvian fissure&#10;D) parietal-occipital fissure

Accepted Answer

The answer of The lateral aspect of the parietal lobe...

Question 12

The ability to point to a touched area of the body without actually being able to feel the touch at a conscious level is called _____.&#10;A) afferent paresis&#10;B) blind touch&#10;C) spooky&#10;D) autopagnosia

Accepted Answer

The answer of The ability to point to a touched...

Question 13

Which is NOT one of the symptoms associated with Balint's syndrome?&#10;A) the inability to fixate on specific visual stimuli&#10;B) the field of attention being limited to one object at a time&#10;C) the inability to name colors&#10;D) the inability to make visually guided movements

Accepted Answer

The answer of Which is NOT one of the symptoms...

Question 14

Which is more likely after left parietal damage?&#10;A) unilateral neglect&#10;B) cube counting&#10;C) dressing disability&#10;D) more errors in Weigl's Sorting Test

Accepted Answer

The answer of Which is more likely after left parietal...

Question 15

A denial of illness is called _____.&#10;A) autopagnosia&#10;B) anosognosia&#10;C) stubbornness&#10;D) afferent denial
