The frontal and parietal lobes were found to be critical for executive control processes, which was demonstrated by significantly worse performance on specific executive functioning subtests in participants with damage to frontal and parietal regions, as well as the white matter tracts connecting these regions, such as the superior fronto ...
Visual extinction is a neurological disorder which occurs following damage to the parietal lobe of the brain. It is similar to, but distinct from, hemispatial neglect . Visual extinction has the characteristic symptom of difficulty to perceive contralesional stimuli when presented simultaneously with an ipsilesional stimulus, but the ability to ...
Gerstmann syndrome is a neurological disorder that is characterized by a constellation of symptoms [1] that suggests the presence of a lesion usually near the junction of the temporal and parietal lobes at or near the angular gyrus. Gerstmann syndrome is typically associated with damage to the inferior parietal lobule of the dominant hemisphere ...
In the two-streams hypothesis, damage to the ventral, or "what" stream, of the visual system, located in the temporal lobe, leads to the symptoms related to general vision and object recognition deficits; damage to the dorsal, or "where/how" stream, located in the parietal lobe, leads to PCA symptoms related to impaired movements in response to ...
Generally, asomatognosia often arises from damage to the right parietal lobe (Whishaw, 2015). Evidence indicates that damage to the right hemisphere often results from a stroke or pre-existing hemispatial neglect, or inattention to the left visual field (Antoniello, 2016) (Keenan, 2004). Individuals who suffer from somatoparaphrenia, a specific ...
Amorphosynthesis is most closely related to damage of the right parietal lobe but instances of left parietal and bilateral damage have also been reported. [16] The inattention to or suppression of somatic sensations on the contralesional side of the body can manifest in the cerebral processing centers that produce the sensory modalities for touch, taste, vision, smell, and proprioception.

Hemispatial neglect is a neuropsychological condition in which, after damage to one hemisphere of the brain (e.g. after a stroke), a deficit in attention and awareness towards the side of space opposite brain damage (contralesional space) is observed.
Anosognosia is a condition in which a person with a disability is cognitively unaware of having it due to an underlying physical condition. Anosognosia results from physiological damage to brain structures, typically to the parietal lobe or a diffuse lesion on the fronto-temporal-parietal area in the right hemisphere, [1] [2] [3] and is thus a neuropsychiatric disorder.
