The amygdala is our so-called “lizard brain” where we feel our most reactive, freaked out, base emotions. Lucky for us humans we also have the cingulate gurus, which talks your lizard brain freakouts over to the frontal lobe for reasoning. Thanks, cingulate gyrus!

Learn all this and more from our fun, fascinating and fact-packed hangtag books, included with every plush organ!

The pineal is a teeny endocrine gland deep inside your brain🧠 that modulates sleep-wake and seasonal cycles! Melatonin is the sleepy substance 💤 that regulates circadian rhythms and gets you to bed. Descartes thought the pineal was the seat of the human soul. The gland is also thought to be the third eye 👁and is named for its pine cone-like shape. If you need a bed buddy, check out our sleep-inducing brand new pineal plush!

Looking for even more Brains? Luckily Houston Museum of Natural Science has a few left. Stay tuned, iheartguts.com will have more plush brains once Spring finally appears!

Are bigger brains necessarily better brains? Sometimes, yes, but not always. It's the quality of the grey matter that counts and, of course, how you use it. For instance, Einstein had an average size brain, but had a humungous area of his parietal lobe, the part of the brain responsible for visual imagery and mathematical thinking. Women have smaller brains than men overall because we tend to be physically smaller. But that doesn't make us dumber, we just use our noodles differently, and, some say, make better use of a smaller space. Also, the additional surface area offered by deeper folds and convolutions on the brains surface can also give the average size brain more thinking power. {via Boing Boing, brain cupcake image courtesy of Me, Myself and Meningioma}
