Why is the inferior parietal lobule important to humans?
Why is the inferior parietal lobule important to humans?
Abstract. Human inferior parietal lobule (IPL) plays a key role in various cognitive functions. Its functional diversity, including attention, language, and action processing, is reflected by its structural segregation into 7 cytoarchitectonically distinct areas, each with characteristic connectivity patterns.
What functional areas are found in the parietal lobe?
The parietal lobes can be divided into two functional regions. One involves sensation and perception and the other is concerned with integrating sensory input, primarily with the visual system. The first function integrates sensory information to form a single perception (cognition).
What is the most important function of the parietal lobe?
Function. The parietal lobe is vital for sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the brain’s primary somatic sensory cortex (see image 2), a region where the brain interprets input from other areas of the body.
What does the superior parietal lobule do?
The superior parietal lobule has close links with the occipital lobe and is involved in aspects of attention and visuospatial perception, including the representation and manipulation of objects. The inferior parietal lobule consists of the angular and supramarginal gyri.
What happens if the inferior parietal lobule is damaged?
Destruction to the inferior parietal lobule of the non-dominant hemisphere results in topographic memory loss, anosognosia, construction apraxia, dressing apraxia, contralateral sensory neglect, contralateral hemianopia, or lower quadrantanopia.
What drugs affect the parietal lobe?
Chronic cocaine use may affect the attentional system in the right parietal lobe, making patients more prone to attentional deficits.
What is the parietal lobe of the brain responsible for?
The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
What happens if the superior parietal lobe is damaged?
Thus, if the parietal lobe is damaged, those nerve signals can’t travel as easily. Parietal lobe damage makes it more difficult to process certain visual information such as length and depth. This leads to poor hand-eye coordination and balance, as well as several other eye problems.
What does the left superior parietal lobule do?
The superior parietal lobule is involved with spatial orientation, and receives a great deal of visual input as well as sensory input from one’s hand. It is also involved with other functions of the parietal lobe in general.
What is the inferior parietal cortex responsible for?
Function. Inferior parietal lobule has been involved in the perception of emotions in facial stimuli, and interpretation of sensory information. The Inferior parietal lobule is concerned with language, mathematical operations, and body image, particularly the supramarginal gyrus and the angular gyrus.
What is the function of the superior parietal lobe?
The superior parietal lobule is involved with spatial orientation, and receives a great deal of visual input as well as sensory input from one’s hand. It is also involved with other functions of the parietal lobe in general.
What is the function of the left frontal lobe?
The left frontal lobe is the front portion of the left cerebrum in the brain, and it controls emotion and personality.
What are the parts of the parietal lobe?
The parietal lobe, posterior to the central sulcus , is divided into three parts: (1) the postcentral gyrus, (2) the superior parietal lobule, and (3) the inferior parietal lobule. The postcentral gyrus receives sensory input from the contralateral half of the body. The sequential representation is the….
Where is the parietal lobe of the cerebral cortex?
[edit on Wikidata] The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus.
