Frontal function
-Voluntary movement (primary motor cortex/precentral gyrus)
- Broca's Area (typically located in the L hemisphere): Speech, concentration
- Personality, temper, judgement, reasoning, behavior, self-awareness, executive functions
Parietal function
- Associated with sensation of touch, kinesthesia, perception of vibration and temperature
- Receives information from other areas of the brain regarding hearing, vision, motor, sensory and memory
- Provides meaning for objects
- Interprets language and w
Temporal function
- primary auditory processing and olfaction
- Wenicke's area (typically located in the L hemisphere): ability to understand and produce meaningful speech, verbal and general memory, assists with understanding language
- The rear of the temporal lobe enabl
Occipital function
- Main processing center for visual information
- processes visual information regarding colors, light, and shapes
- Judgment of distance, seeing in three dimentions
Frontal lobe impairment
- contralateral weakness
- perseveration, inattention
- personality changes, antisocial behavior
- impaired concentration, apathy
- Broco's aphasia
- delayed or poor initiation
- emotional lability
Parietal lobe impairment
- dominant hemisphere (usually left): agraphia, alexia, agnosia
- non dominant hemispher: dressing apraxia, constructional apraxia, anosognosia
- contralateral sensory deficits, impaired language comprehension, impaired taste
Temporal lobe impairment
- Learning deficits
- Wernicke's aphasia (receptive deficits)
- Antisocial, aggressive behaviors
- Difficulty with facial recognition
- Difficulty with memory, memory loss
- Inability to categorize objects
Occipital lobe impairment
- homonymous hemianopsia
- impaired extraocular muscle movement and visual deficits
- impaired color recognition
- reading and writing impairment
- cortical blindness with B lobe involvement
