Philosophy of The Center

• Foster Interdisciplinary Collaborations. • Provide Assess to BOTH Equipment & Training.• Lead Paradigm Shift Within The Neurosciences:

–- Move from “neural phrenology” to Understanding Brain’s Neural Spatial & Temporal Interconnectivty.–- Address Characteristics of Processing In and Between Brain Regions.

Additional Benefits

Concussion Intervention

Concussion

Issues in Assessing Sports Concussion• 1. Little information on brain & behavior prior to

concussion.

• 2. Little long-term follow-up following concussion using standardized testing.

• 3. Tests not comprehensive (e.g., ImPACT not effective in measuring attention, working memory).

• 4. Little information available regarding prior head injuries.

• 5. Falsification of pre-season tests by athletes.

• 6. Pressure to resume play following possible head injury.

• 7. No research-based information regarding when players can be safely returned to play.

Future Possibilities

• Use brain imaging procedures to identify distortions produced by brain injury.

• Identify intervention that can produce more normal neural processing.

• Use the successful intervention to enable individual to perceive and interact with the world in more normal fashion.
