Fearfully and Wonderfully Made

“I praise you, for I am fearfully and wonderfully made” (Psalm 139:14). This verse has come to mind as we’re learning about the human brain in psychology class recently. I haven’t studied anything more fascinating in a long time. The complexities are so vast they seem limitless. Indeed, the brain can never fully understand itself.

As you read this sentence right now, billions of neurons are firing off and chemicals are shooting through what are called “synapses” (gaps between neurons) in various regions of your brain. These neurons are firing off in a precise way in a complex neural network in order to tap into the regions of the brain dedicated to not only visually perceiving the words, but also regions for interpreting and recalling. If you read out loud, you use others regions as well to pull off this intricate process. It all happens so seamlessly, however, that you would probably guess that reading only uses a small part of the brain.

Both hemispheres of your brain are connected and work together to accomplish tasks. Some time ago, doctors began doing “brain splitting,” taking out the connection between the two hemispheres. The result? The brain was only insignificantly affected! Families and friends of these patients barely noticed a difference. Some strange little side-effects did result, though. For example, a person with a split brain can copy two pictures simultaneously by hand without getting confused. It’s an example of the right hand not knowing what the left is doing, or in this case, brain hemispheres. The author of my textbook humorously imagined a split-brained patient playing a game of rock-paper-scissors with himself (left vs. right). Like I said, absolutely fascinating stuff!

Men’s and women’s brains are also programmed slightly differently. While both have proved consistently to have about equal intelligence, their brains don’t work in the same way. Men have more neural connections between regions in the brain (and generally work better with math related things), while women have more cells dedicated to memory and verbal skills. Women’s brains also have features that help it better maintain internal balances, which handle certain types of stress and such. It’s been suggested that this is an adaptation due to childbirth and other maternally related stressors.

I hope it doesn’t seem like I’m trying to bore you with a biology lecture. I am just once again so amazed by God’s creative handiwork. He’s created our brains in such a complex way that even with our latest technological developments, we only understand how about 10 percent of our brain works directly. Side note: The myth that we only use 10 percent of our brains isn’t true. We just only understand how that 10 percent actually works. I would encourage you to research this topic some more on your own, because there’s far too much I could say. Unfortunately, I’ve probably already surpassed the average attention span for a blog (sorry!). Praise God for creating us so fearfully and wonderfully! Let us praise him because he made us and completely understands every aspect of our being.

    I find all of this stuff equally fascinating; it’s actually part of how I ended up in a medical profession. Frequently I find myself thinking “…and someone really thinks a big bang could make this happen…?”

    My thoughts exactly. I listen to them lecture about this stuff without any awe or amazement, and that always surprises me. I hope I never get too smart for myself and think I understand these things better than I do

    i love the medical geeky facts! (being a nurse it’s part of my job description lol) It is awesome how our God has made us so complex. I am with Leanne, just don’t get how people could put blinders on and say that there is no God.
