Features
Read full description

Neuromapper allows for a more efficient and sophisticated multi-dimensional behavioral brain mapping. It contains multiple cognitive and sensory paradigms that were selected based on current practice, known brain behavioral correlates and from review of neuroimaging and clinical research. Neuromapper allows for customized stimulus selection tailored to the patient's ability level and it will record the patient's accuracy and other sensitive behavioral metrics during baseline testing and incorporate that data into the mapping session to provide a more individualized, tailored testing approach. Neuromapper, in its current form, contains paradigms designed to assess language, learning/memory, executive functions, and vision/neglect. Additional paradigms are being researched and designed and a research consortium is being established between the Medical College and other academic centers to continue testing and developing these paradigms and to answer other important research questions about functional localization and clinical mapping.
