| Questão | Responda |
| Subdivisions of the parietal lobes | Postcentral gyrus, superior parietal lobule, parietal operculum, supramarginal gyrus and angular gyrus. |
| Inferior parietal lobule | Supramarginal gyrus and angular gyrus. |
| Anterior zones | Process somatic sensations and perceptions - somatosensory cortex. |
| Posterior zones | Integrate information from vision with somatosensory information for movement - posterior parietal cortex. |
| Object recognition | Spatial information is used as viewer centered object identification - posterior parietal cortex |
| Guidance of movement | Spatial information is sensitive to eye movements - posterior parietal cortex. |
| Cognitive spatial map | Route knowledge, unconscious knowledge of how to reach a destination |
| Symptoms that do not fit with the visuomotor view of the parietal lobe | Difficulties with arithmetic, certain aspects of language, and movement sequences |
| Acalculia | Inability to do arithmetic in parietal lobe patients, might result from the spatial properties of addition and subtraction |
| Language | Words have spatial organization - tap vs. pat. |
| Movement sequencing | Individual elements of the movement have a spatial organization |
| Lesions to the postcentral gyrus | Abnormally high sensory thresholds, impaired position sense, deficits in stereognosis, or tactile perception |
| Astereognosis | Inability to recognize an object by touch |
| Simultaneous extinction | Two stimuli are applied simultaneously to opposite sides of the body, failure to report a stimulus on one side is referred to as extinction |
| Contralateral neglect | Neglect for visual, auditory, and somesthetic stimulation on one side of the body or space |
| Recovering from contralateral neglect | Patients go through allesthesia then simultaneous extinction. |
| Allesthesia | Respond to the neglected stimuli as if they were on the other side of the body or space. |
| Lesions and contralateral neglect | Lesion most often in the right inferior parietal lobe - right intraparietal sulcus and the right angular gyrus |
| Object recognition and lobe damage | After right parietal lobe lesions patients are poor at recognizing objects in unfamiliar views |
| Apraxia | Movement 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 |
| Ideomotor apraxia | Cannot copy serial movements, associated with left parietal lesions |
| Constructional apraxia | Cannot copy pictures, build puzzles, or copy a series of facial movements, associated with right and left parietal lesions |
| Deficits in drawing | Appear after damage to the right parietal lobe |
| Spatial attention | Function of the parietal lobe to selectively attend to different stimuli |
| Disengagement | Shifting attention from one stimulus to the next |
| Mental rotation | Requires mental imaging of the stimulus and manipulation of the image. |
| Spatial cognition and left hemisphere deficit | Result from the inability to generate the image |
| Spatial cognition and right hemisphere deficit | Result from the inability to manipulate the image |
