Brain performs a complex calculation that works like the Global Positioning System, the brain is organized to help us move to different direction in life. The parietal cortex is the part of the brain that takes decisions and implements it. It integrates information coming in from various senses and helps us to understand what action to take.
Single cells in parietal cortex take in streams of sensory information to help us get oriented, but those individual cells also cluster together in larger modules that work together. Those modules in the parietal cortex generate a physical response and, at the same time, are able to reconfigure themselves as we learn and make memories.
These different modules are communicating to each other and seem to be changing their connections just like single cells change their connections. Large groups of cells are connected in different ways as we learn and remember how to take series of actions every day.
Brain always links previous actions with certain places, that is why it is easy to locate a place you have visited before, breaking down of this process leads to Alzheimer's disease and neurological disorders.
