I'll leave this quote from Timothy Leary here, it is old so don't nitpick the numbers, but relevant " The facts of the neurological capacities of the human being are simply astronomical. We possess, each of us, around 10 billion brain cells. This is several times the number of human beings in the world. Any one brain cell can be in relationship with as many as 25,000 others. The number of possible associations is of the order of 10 billion to the twenty-five thousandth power, a quantity larger than the number of atoms in the universe. This electrical-chemical network, inconceivable in its complexity, is the anatomical structure of consciousness..."
