Weekly Photo Challenge: It’s All In Your Head

This week’s challenge is all about things you admire, so I decided on something a little less..conventional. Do not adjust your set; that is a real human brain, preserved in epoxy and currently on display at the Exploratorium. Take step back and consider all that a human brain does. Controlling your body’s functions, from the senses and sleep to memories and sheer, raw emotion. Keeping you breathing and balanced. Reading this sentence and processing the little squiggles into letters and words, and thus their meaning. A complex organic machine connected via trillions of synapses. For all the dangers out there, it’s allowed us to become the dominant species on the planet. We survive, thrive, create, accomplish, and it’s all because these little clumps of matter are developed just enough to make it happen. Yeah, it’s worth admiration. A larger version is viewable here.
