Parietal Lobes Flashcards
Cards in this deck (28)
- 1Subdivisions of the parietal lobesPostcentral gyrus, superior parietal lobule, parietal operculum, supramarginal gyrus and angular gyrus.
- 2Inferior parietal lobuleSupramarginal gyrus and angular gyrus.
- 3Anterior zonesProcess somatic sensations and perceptions - somatosensory cortex.
- 4Posterior zonesIntegrate information from vision with somatosensory information for movement - posterior parietal cortex.
- 5Object recognitionSpatial information is used as viewer centered object identification - posterior parietal cortex
- 6Guidance of movementSpatial information is sensitive to eye movements - posterior parietal cortex.
- 7Cognitive spatial mapRoute knowledge, unconscious knowledge of how to reach a destination
- 8Symptoms that do not fit with the visuomotor view of the parietal lobeDifficulties with arithmetic, certain aspects of language, and movement sequences
- 9AcalculiaInability to do arithmetic in parietal lobe patients, might result from the spatial properties of addition and subtraction
- 10LanguageWords have spatial organization - tap vs. pat.
- 11Movement sequencingIndividual elements of the movement have a spatial organization
- 12Lesions to the postcentral gyrusAbnormally high sensory thresholds, impaired position sense, deficits in stereognosis, or tactile perception
- 13AstereognosisInability to recognize an object by touch
- 14Simultaneous extinctionTwo stimuli are applied simultaneously to opposite sides of the body, failure to report a stimulus on one side is referred to as extinction
- 15Contralateral neglectNeglect for visual, auditory, and somesthetic stimulation on one side of the body or space
- 16Recovering from contralateral neglectPatients go through allesthesia then simultaneous extinction.
- 17AllesthesiaRespond to the neglected stimuli as if they were on the other side of the body or space.
- 18Lesions and contralateral neglectLesion most often in the right inferior parietal lobe - right intraparietal sulcus and the right angular gyrus
- 19Object recognition and lobe damageAfter right parietal lobe lesions patients are poor at recognizing objects in unfamiliar views
- 20ApraxiaMovement disorder in which the loss of movement is not caused by weakness, inability to move, abnormal muscle tone, intellectual deterioration, poor comprehension, or other disorders of movement
- 21Ideomotor apraxiaCannot copy serial movements, associated with left parietal lesions
- 22Constructional apraxiaCannot copy pictures, build puzzles, or copy a series of facial movements, associated with right and left parietal lesions
- 23Deficits in drawingAppear after damage to the right parietal lobe
- 24Spatial attentionFunction of the parietal lobe to selectively attend to different stimuli
- 25DisengagementShifting attention from one stimulus to the next
- 26Mental rotationRequires mental imaging of the stimulus and manipulation of the image.
- 27Spatial cognition and left hemisphere deficitResult from the inability to generate the image
- 28Spatial cognition and right hemisphere deficitResult from the inability to manipulate the image
