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.

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.
