Neuropsychology Core

About Us

Neuropsychology is the study of brain-behavior relationships. Neuropsychologists apply principles of assessment and intervention based upon the scientific study of human behavior as it relates to normal and abnormal functioning of the central nervous system. 


  • Collaboration on study design and grant proposals
  • Determining the neurodevelopmental or neuropsychological assessment battery to address research questions
  • Data collection and interpretation (data collection only is available for Industry and consortium studies)
  • Writing the neuropsych-related portions of posters and manuscripts
