List Rules Vote up the brainiest facts that totally blow your mind.

Our brains are intricate machines, capable of some truly remarkable tasks - tasks of which most of us are unaware. There is a practically endless roster of fascinating - and even creepily unsettling - facts about the human brain, which only further illustrates the astonishing capabilities and complexities of this crucial organ. Since it's so easy to take for granted all the ways our brains serve and protect us, we've assembled a list with just a small sampling of fascinating things to learn about your brain.

First: a little background on just what the brain does. We humans have the largest brains of any mammal relative to body size. It essentially serves as the body's "command center." It regulates the nervous system, processing information from the sensory organs and sending information to the muscles of the body. Different areas of the brain are responsible for processing and carrying out different tasks, but in a very real sense, all the disparate parts work together to keep us functioning, protected, and prepared - oh, and alive.

The Brain Can't Feel Pain

It may be the height of irony. The brain is the "control center" that processes pain, telling us when something is wrong or when we need to pay closer attention to a particular part of the body. Yet the brain itself is not capable of feeling pain because it has no pain receptors. What about headaches, then? Surely we feel pain with a headache, as anyone who suffers from migraines can tell you. Actually, headache pain does not come from the brain itself; it comes from the layers of tissue that shield the brain and skull.

Chronic Stress Causes The Brain To Shrink

Stress takes a toll on the body, mind, and spirit. And regular, chronic stress can actually cause the brain to shrink in size. Release of the stress hormone cortisol may decrease the size and effective functioning of the brain's neurons. PTSD and other issues of unresolved trauma often shrink the hippocampus, the area of the brain which forms new memories. The neurons in the prefrontal cortex, too, may also shrink in response to major life stressors. If you were looking for more proof that good stress management skills are important to optimum brain health, here it is.

Your Brain Is Soft, Like Butter

Upon first glance, you might assume that the brain is firm and rubbery. In reality, it's more malleable than that - much more malleable, almost the consistency of soft butter. "It's so soft that even just a collision with the inside of your skull can give you brain damage," said Dr. Cameron Shaw. "Or it'll set off catastrophic swelling that can crush your brain inside the skull." An unsettling and creepy thought, to be sure, but further proof that we all need to take a proactive role in fortifying and safeguarding our brains.

Certain Foods Really Are "Brain Food"

Specific foods have been shown to boost brain power and support better brain function. Adult brains still have the capacity to make new neurons, which are the foundations of learning, memory, and how our brains and bodies respond to stress. To foster the development of new neurons, incorporating brain-friendly foods into your diet can be a big help. Among them: walnuts, eggs, salmon, avocados, and - hurrah! - champagne. Also: get plenty of sleep and regular aerobic exercise; don't rely solely on the champagne.
