What is the parahippocampal gyrus?
Parahippocampal gyrus is an important and active area of the brain limbic system. Its main feature includes memory creation and evoking visual scenes. Recognition of certain communication stimuli can serve as other functions. The name of the structure comes from its vicinity to the hippocamp. Abnormalities may indicate basic conditions such as schizophrenia, Alzheimer's disease and hippocampal sclerosis. Includes the front and rear areas. Entorhinal and perihinal cortics contain the front part. Combined with parts of the nearby structured called Fusiform Gyrus, the whole area is referred to as the parahippocampal bark. The structure also rests inside the side of the brain brain known as a time lobe, whose main feature is hippocampus, part of the brain, which usually deals with short and long -term memory.
Memory plays an important role in Parahippocampal Gyrus as well and the recognition of scenes is the most common memory -related function. Scenes include visual allusions such as landscapes orroom composition. Scientists believe that there is a connection between the parahippocampal gyr and the scene recognition, because this part of the brain shows a high activity when exposed to these types of images. In addition, individuals with damage to this area show a significant decline in understanding and understanding of collective scenes.
Parts of the parahippocampal gyrus can also equip individuals with valuable communication tools. Like the structure, it helps to identify the background in visual allusions, it can also provide basic information for verbal communication. Fine verbal allusions, such as sarcasm or inflexion, can be processed and stored by the right gyrus.
Many scientists combined unusual brain structures with different conditions, in particular mental illnesses. In the case of paraahippocampal gyro, individuals of diagnosed schizophrenia often occur changes in thickness, volume and symmetry. Many forms of itThe status has the inability to recognize reality. One of the main features of the parahippocampal gyruse actually creates associations and gives cohesive meaning to various stimuli that enter the brain.
Other conditions are possible associated with the damaged temporary lobe structure include Alzheimer's disease and hippocampal sclerosis. One of the characteristics of Alzheimer's disease is memory disorder, which provides correlation observed abnormalities in the papócampal gyru focused on memory. Individuals with progressive condition also have difficulty detecting other proposed functions Gyrus: sarcasm.
When hippocampus and close structures such as paraahippocampal gyrus, atrophy begin and lose function, hippocampal sclerosis may occur. Seizures are one mpřínak disease. This condition can also slowly damage or even destroy nerve and brain cells.
