Houghton Mifflin Harcourt, 2012 (i-xxii, 359 pages) QUOTES ABOUT CONSCIOUSNESS "Neurons continue to grow branches well after birth. This process is called the 'wiring' of the brain, since axons and dendrites resemble wires. Axons have to grow the most, since they are much longer than dendrites. Imagine the tiny growing tip of an axon, known as a 'growth cone' for its roughly conical shape." (106) "If a growth cone were expanded to human size, its travels would take it to the other side of a city. How is the growth cone able to navigate such long distances? Many neuroscientists study this phenomenon, and they've found that the growth cone acts like a dog sniffing its way home." (106) "The surfaces of neurons are coated with special guidance molecules that act like scents on the ground, and the interstitial spaces between neurons contain drifting guidance molecules that act like scents in the air. Growth cones are equipped with molecular sensors and can "smell" the guidance molecules to find their destination." (106) "The production of guidance molecules and sensors for these molecules is under genetic control ... That's how genes guide the wiring of the brain."
