Your Brain Has 500 Trillion Connections
Your body, including your brain, is fearfully and wonderfully made. In the book Does My Goldfish Know Who I Am? science writer Joshua Foer explains to a nine-year-old boy named Tom how the brain can store so much information despite being that small:
An adult's brain only weighs about [three pounds], but it's made up of about 100 billion microscopic neurons. Each of those neurons looks like a tiny branching tree, whose limbs reach out and touch other neurons. In fact, each neuron can make between 5,000 and 10,000 connections with other neurons—sometimes even more. That's more than 500 trillion connections! A memory is essentially a pattern of connections between neurons.
Every sensation that you remember, every thought that you think, transforms your brain by altering the connections within that vast network. By the time you get to the end of this sentence, you will have created a new memory, which means your brain will have physically changed.
Possible Preaching Angles: (1) Creation; Self-image—Scripture is right: You are fearfully and wonderfully made. (2) Scripture Reading; Meditation; Renewal of the Mind—Our thoughts really do make a difference. The way we think and meditate creates a new "pattern of connections between neurons." (3) God, wisdom of—If our brains are this complex, imagine the depth and complexity of the "mind of God."
