The following images show the complex networking of neurological activity involved in brain functioning. They depict the remarkable advances in imaging technology called Diffusion Tensor Imaging and can show damage areas of the brain, as well as the disruption in transmission of cellular activity.
Brain Imaging Technology
White matter fiber tracking derived from Diffusion Tensor Imaging (DTI). The paths of fibers passing through the corpus callosum were tracked. Red represents fibers running primarily left/right. Blue is up/down, and green is front/back.

Diffusion Tensor Imaging of Frontal Cortex

Diffusion Tensor Imaging (DTI) revealing connectivity in the brain
This movie depicts fibers of "connectivity" in the brain, as seen through diffusion tensor imaging (DTI), an MRI technique. The pulses of light travel along each fiber, tracing beginning to end; the pulses go only one way in this animation. The resulting visual conveys the concept of information flow through the brain's "wiring."
What Are Brain Injuries?
There are many ways in which you or a loved one may sustain a brain injury. We are most familiar with brain injuries that are caused by accidents from automobiles, motorcycles, and bicycles, and more recently we have witnessed a growing concern from sports-related brain injuries and concussions, such as football. We continue to learn more about the pervasive effect blasts from explosives by our veterans returning home from war overseas.
One of the well-known cases of brain injury in which a blasting charge sent a 1.5” wide and 3’ long metal spike through his face and frontal lobe. Mr. Gage suffered profound cognitive deficits and problems with social behavior.
Although some brain injuries stories are not quite as striking as Phineas Gage or the photo above, other types of brain injuries can bring on devastating results.
Falls continue to be a leading cause of brain injuries, especially for small children and older adults. Falls in the workplace contribute to brain injuries and many new safety initiatives can be developed and introduced to vastly reduce the incidents of injuries.
