In The Many Faces of TRAUMATIC BRAIN INJURY, brain injury expert witness Dr. John D. Lloyd, PhD, MErgS, CPE, CBIS, writes:
The brain is the most complex thing in the world. A baby’s brain at birth, weighing about 1 pound is already one-third the size of a typical 3-pound adult brain. And if we consider that there are one million nerve cells in a section of brain the size of a grain of rice, it is impossible to comprehend the billions and billions of neuronal pathways in an average brain. In fact, there are more neural connections in each brain than there are stars in the sky. A baby’s brain is the last of the major organs to develop in utero, where neurons are born from the division of a stem cell. Unlike most cells in the body, which die and are replaced, neurons, which are formed in the fetus, are designed to last for a lifetime.
There are two primary mechanisms associated with traumatic brain injury – impact loading and impulse loading.
