Cerebrum

Question 1

Functions of Frontal Lobe

Answer 1

Voluntary movement, intellect, orientation, speech, concentration, personality, temper, judgment reasoning, behavior, self-awareness, executive functions

Question 2

Impairments due to frontal lobe injury

Answer 2

Contralateral weakness, perseveration, inattention, personality changes, antisocial behavior, impaired concentration, apathy, Broca’s aphasia, delayed or poor initiaion, emotional lability

Question 3

What is broca’s apahsia? Which lobe is it involved with?

Answer 3

Frontal lobe damage. Broca’s aphasia is expressive deficits - a type of non-fluent aphasia. Intact auditory and reading comprehension. Impaired repetition and naming skills. Frustration with language skills errors.

Question 4

Functions of the parietal lobe

Answer 4

sensation of touch, kinesthesia, perception of vibration, temperature; receives information from other area of the brain regarding hearing, vision, motor, sensory, and memory; provides meaning for objects; interprets meaning for objects; interprets language; spatial and visual perception

Question 5

Impairments due to parietal lobe injury

Answer 5

contalateral sensory deficits, impaired language comprehension, impaired taste

Question 6

Dominant versus non-dominant hemisphere impairments of the pariettal lobe

Answer 6

Dominant lesion (usually left) - agraphia, alexia, agnosia
Non-dominant lesion (right)  - dressing apraxia, consructional apraxia, anosognosia

Question 7

Function of the temporal lobe

Answer 7

primary auditory processing and olfaction; understanding and producing meaningful speech; interpretation of emotions

Question 8

Impairments due to temporal lobe injuries

Answer 8

learning deficits; wernicke’s aphasia; antisocial behaviors; difficulty with facial recognition;memory loss; inability to categorize objects

Question 9

What is Wernicke’s aphasia? Which lobe is it involved with?

Answer 9

Temporal lobe damage. Receptive aphasia. comprehension (reading/auditory) is impaired; good artiulation; impaired writing; poor naming ability. A type of fluent aphasia

Question 10

Fluent versus non-fluent aphasias

Answer 10

Fluent: Word output and speech production are functional, however the speech lacks substance - commonly use neologisms

Non-fluent: poor word output and dysprosodic speech; poor articulation; content is present

Question 11

Functions of the occipital lobe

Answer 11

visual information processing; judgment of distance

Question 12

Impairments due to occipital lobe injuries

Answer 12

homonymous hemianopsia; impaired extraocular muscle movement and visual deficits; impaired color recognition; reading and writing imparment; cortical blindness with bilateral lobe involvement
