Lobes Of Cerebrum

Question 1

Functions of frontal lobe

Answer 1

• voluntary movement (primary motor cortex/precentral gyrus), intellect, orientation
• Broca’s area (typically located in the LEFT hemisphere): speech, concentration
• personality, temper, judgement, reasoning, behavior, self-awareness, executive functions

Question 2

Impairments in frontal lobe

Answer 2

• contralateral weakness
• perseveration, inattention
• personality changes, antisocial behavior
• impaired concentration, apathy
• Broca’s aphasia (expressive deficits)
• delayed or poor initiation
• emotional lability

Question 3

Function of parietal lobe

Answer 3

• associated with sensation of touch, kinesthesia, perception of vibration, and temperature
• receives info from other areas of the brain regarding hearing, vision, motor, sensory, and memory
• provides meaning for objects
• interprets language and words
• spatial and visual perception

Question 4

Impairments of parietal lobe

Answer 4

• dominant hemisphere (typically located in the left hemisphere): agraphia, alexia, agnosia
• non-dominant hemisphere (typically located in the RIGHT hemisphere): dressing apraxia, constructional apraxia, anosognosia
• contralateral sensory deficits
• impaired language comprehension
• impaired taste

Question 5

Functions of temporal lobe

Answer 5

• primary auditory processing and olfaction
• Wernicke’s area (typically located in the LEFT hemisphere): ability to understand and produce meaningful speech, verbal and general memory, assists with understanding language
• the rear of the temporal lobe enables humans to interpret other people’s emotions and reactions

Question 6

Impairment of temporal lobe

Answer 6

• learning deficits
• Wernicke’s aphasia (receptive deficits)
• antisocial, aggresive behaviors
• difficulty with facial recognition
• difficulty with memory, memory loss
• inability to categorize objects

Question 7

Function of occipital lobe

Answer 7

• main processing center for visual information
• processes visual info regarding colors, light, and shapes
• judgement of distance, seeing in three dimension

Question 8

Impairments of occipital lobe

Answer 8

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