Intelle Brain The human brain is very extraordinary and fascinating. Research shows that the brain has between 100-200 billion nerve cells called neurons. Each of these neurons is connected to other thousands of neurons. The number of connections between neurons in the human brain is more than the stars in our galaxy. The neurons produce electricity when they communicate with each other. They pass information to each other using tiny electrical currents. When millions of neurons communicate with each other at once, they produce strong electrical activity. Some researchers estimate that an active brain can produce 10 watts of electrical activity. This is why the brain is called an electromagnetic organ. Brain electrical activity is described in terms of brain waves. Brain waves are like radio waves as a form of electromagnetic energy that travels at the speed of light. Like radio waves -and all waves- brain waves have electrical frequencies. A frequency is the number of times a wa...
