Functional Areas and Functions/Dysfunctions Flashcards
Primary Somatomotor Cortex
Executing Movement
Dysfunction: contralateral paresis, loss of fractionation
Premotor Areas
Planning Movement
Dysfunction: Apraxias, Deficits in sequential movements and bimanual coordination
Broca’s Area
Production of language
Dysfunction: Expressive Aphasia
Prefrontal Cortex (anterior multimodal association cortex)
Sensory Integration and selection of appropriate motor responses (intention)
Cognition
Dysfunction: behavioral abnormalities, apraxias
Primary Somatosensory Cortex
Somatosensory Perception
Dysfunction: contralateral sensory loss
Secondary Somatosensory Cortex
Somatosensory Interpretation
Dysfunction: Decreased discrimination of both shape and texture, impaired learning of new tactile
Wernicke’s Area
Comprehension of Language
Dysfunction: Receptive Aphasia
Posterior Parietal Cortex
Attention and Skilled motor functions
Dysfunction: contralateral neglect, apraxias
Parietal-Temporal-Occipital Association Cortex (posterior multimodal association cortex)
Stimuli integration; Spatial relationships, attention, recognition
Dysfunction: contralateral neglect, agnosias, apraxias
Primary Auditory Cortex
Auditory Perception
Dysfunction: Decreased Sound Localization or discrimination of tones
Secondary Auditory Cortex
Auditory Interpretation
Dysfunction: Aphasia (receptive)
Primary Visual Cortex
Visual Perception
Dysfunction: Contralateral Homonymous Hemianopia
Secondary Visual Cortex
Visual Interpretation
Dysfunction: dependent on region:
- middle temporal area: cerebral akinetopsia, decreased depth perception
Primary Taste Cortex
Taste Perception
Dysfunction: disorders of taste
Part of Limbic System
Important in emotional states, drive-related behavior, and memory formation
