The human brain is comprised of roughly one hundred billion neurones, which are thereupon interconnected by trillions of connections, called synapses. Each of these associations may be relaying between one and a thousand transmissions per second, to fabricate the process which we equate to as thoughts or ideas in the physical brain.
To fully comprehend your thinking, it is necessary to appreciate that the human brain is just part of a complex system which entails the entire cognitive form. Your thoughts become manifest, not merely as electrochemical connections of the brain, but also as electromagnetic impulses. Some cognitive scientists have started to acknowledge that thoughts are not confined to the brain, but concurrently occur in the body as well as the brain. It is this electromagnetic nature of thoughts and ideas, which enable them to spread through the brain, the body and the environment around us.
