Cerebral Cortex Flashcards
(26 cards)
What are the four main lobes of the cerebral cortex?
Frontal, Parietal, Temporal, Occipital.
Function of the frontal lobe?
Higher executive functions, voluntary movement, speech production.
Function of the parietal lobe?
Sensory integration, perception, visuospatial processing.
Function of the temporal lobe?
Auditory processing, language comprehension, memory, emotions.
Function of the occipital lobe?
Visual processing.
What is the function of the primary motor cortex?
Controls voluntary movements.
What is the function of the primary somatosensory cortex?
Conscious perception of touch, pressure, pain, and temperature.
Where is the primary auditory cortex located?
In the temporal lobe.
Where is the primary visual cortex located?
In the occipital lobe.
What is the function of the prefrontal cortex?
Planning, decision-making, personality, morality.
What is the parieto-occipitotemporal area responsible for?
Language comprehension, naming objects, reading, spatial analysis.
What does the limbic association area control?
Emotions, motivation, memory, behavior.
Where is Broca’s area located and what is its function?
In the frontal lobe; responsible for speech production.
Where is Wernicke’s area and what does it control?
In the temporal lobe; responsible for language comprehension.
What functions are associated with the left hemisphere?
Language, logic, mathematics, analytical thinking.
What functions are associated with the right hemisphere?
Spatial awareness, emotion, intuition, art, music
What is hemineglect and what causes it?
Inattention to one side of space (usually the left); caused by a lesion in the right parietal lobe.
What type of aphasia is caused by a lesion in Broca’s area?
Non-fluent (expressive) aphasia – broken speech with good comprehension
What happens if Wernicke’s area is damaged?
Fluent (receptive) aphasia – fluent but meaningless speech (“word salad”).
What does a lesion in the left primary motor cortex cause?
Weakness/paralysis in the right side of the body.
Lesion in the left primary motor cortex most likely causes:
A. Weakness in right upper extremity
B. Loss of short-term memory
C. Paralysis of left side of the body
D. Loss of scaling sense
A. Weakness in right upper extremity
The motor area of speech is called:
A. Broca’s area
B. Wernicke’s area
C. Limbic association area
D. Primary motor cortex
A. Broca’s area
Which lobe is primarily responsible for visual processing?
A. Frontal
B. Temporal
C. Parietal
D. Occipital
D. Occipital
A lesion in Wernicke’s area results in:
A. Motor aphasia
B. Receptive aphasia
C. Ataxia
D. Hemineglect
B. Receptive aphasia
