Picture this: Earth has made its first contact with an extraterrestrial species, and, as to be expected, their anatomy and nervous system are entirely different from our own. Rather than having a single brain where all sensory information and motor controls are processed, they have nine brains. Rather than having a rigid skeleton, they have compact arrays of muscle tissue that stiffen and soften when they move, and their many limbs have an infinite number of degrees of freedom. Oh, and they can only breath underwater, too.

Attempting to “Knock Out” the Causes of Concussions
Approximately every 15 seconds, a traumatic brain injury occurs in the U.S. A concussion is a form of mild traumatic brain injury produced by a contact or inertial force to the head (or neck) area. A concussion causes the brain to rapidly move around inside the skull, harming natural brain function. According to the Brain Injury Research Institute, roughly 1.6 to 3.8 million concussions occur each year in the U.S., resulting from both recreation and sports related incidents. In fact, brain injuries cause more deaths than any other sports injury.

Have you ever wondered why one of the most mysterious organ in our body, the brain, has a distinctive shape which has a strong resemblance to a walnut? Or, what are the major factors that could play a significant role in developing its particular shape, with crests and valleys, that wires our motions, senses, feelings and thoughts, which makes each one of us a unique human being?

Have you ever wondered how a woodpecker is capable of banging its head against a tree so furiously without seriously injuring itself? The impact of a woodpecker’s beak with a tree can exceed speeds of up to 6 meters per second and occur over 12,000 times a day.These kinds of numbers are what allow woodpeckers to smash through trees to get to those tasty bugs that live inside.

Traumatic brain injuries (TBI) are injuries to the brain due to some kind of trauma and are more commonly called concussions. All TBI are unique and are not created equally. “Sports Medicine,” “Biomechanics of Concussions,” and “Concussion Connection” shed some light on subject and determine what combination of forces and accelerations tend to cause the most damage to the brain.

Our brains are made of a very soft material but luckily our skulls provide the brain protection from the outside world. However, during violent movements the brain is free to move inside the skull and collide with the skull. This impact can cause injury to the brain, known as a concussion, that can lead to various symptoms depending on severity.
