What is an inferior parietal lobe?
Parietal lobe in the brain helps integrate sensory information and determine the positions of objects in the space, among other things. An important part of this part of the brain is the lower parietal lobe (IPL), also known as the lower parietal lobles. This area lies only better than a time lobe and consists of two ridges known as Gyri.
Several functions were attributed to the lower parietal lobe, some of which can be determined on the basis of the parts of which receive signals. Studies have shown that hippocampus, cerebellum and excellent colliculus have a strong neuronal connection with this lobule. These brain areas help individuals to orient themselves in space and are involved in the engine function.
, as they are, contribute to certain IPL features such as the establishment of the outside world maps. Among other functions in which these connections are involved in the eye involving eye movement. Such actions related to attention include the directing of someone's view of objects of interest. The integration of sensory input and movement is importantby an altogether feature of the lower parietal lobe.
The lower parietal lobe is not the same size in both hemispheres. In this part of the bark there are also differences in sex size. Males have a larger IPL on the left hemisphere and women show a larger IPL size on the right hemisphere. Overall, the size of this area is also more massive in men.
The differences in the size between the hemisphere are underlined by the functional differences. Neurons in the lower parietal lobe are dominant in their activity on the right hemisphere. Therefore, they will be easier to respond to the events of detected sensory neurons in the body, especially on the left side.
According to the research, the left side of the body can detect sensory and tactile changes with greater sensitivity. The left hand is easier to detect the differences in weight between objects. It can also determine the temperature differences better than the right hand. This dominance is caused by the activity and sensitivity of neurons in IPL, not because of the differences in sensory cellularH on the left side of the body.
Along with the integration of sensory inputs concerning touch and vision IPL also integrates pain signals. Parts of one IPL, known as supramarginal gyrus, show sensitivity to pain. One of these parts helps the body to determine where the source of pain comes. Damage to these areas may result in greater pain tolerance or inability to assign the emotional significance of pain.
