What is a grid cell?
It is found in hippocamp and other areas of the brain associated with memory and spatial consciousness, the grid cell creates an electrical activity that represents the environment of the organism. It is one of the three types of neurons that map the environment from the brain. Grid cells, discovered in the mouse brains in 2005, create triangle -shaped grids that are expected to be a physical location. They were detected in the human brains in 2010 by means of detection of a neurological electrical response in relation to spatial bars of terrain and objects in a virtual reality environment. Geometric formulas that represent electrical activity in cells can be drafted by imaging devices and computers. Although they tend to be arranged in triangles, the effect is a line of latitude and length, such as the analysis of the information that is created in The Brain. The activity of the grid cells is complemented by the function of the cells of the cells to be fired appropriately when a person or animal remains in a certain position and hlavian cells that sensory direction. The brain can process information and remember the sights in an unknown environment.
The function of the grid is affected by Alzheimer's disease because it is found in the areas of the brain where the disease begins. Patients with Alzheimer's disease often experience disorientation, and problems with the memory of spatial details soon and disruption of grid cell mapping capacity may be a reason. These neurons provide the perception of the environment and memories. Without a map created by the activity of the grid, which serves as a guide, the brain is unable to process information for spatial consciousness sufficiently.
Data collected by mapping the location of grid cells and associated activities is also beneficial for neurosurgeons. By displaying the brain's electrical activity and the analysis of electrical signals they can measure what areas are affected by diseases such as Alzheimer or epilepsy, and use information asHandbook during operation. The electrical activity of the grid cell is symmetrical about the circle, while the triangular segmentation occurs in six different areas. Faster movement and changes in the environment cause cells to shoot more often; Changes in direction and speed are immediately detected so that the brain can reformulate the internal image of the environment.
