Title: N/A
Brief Summary: Cognitive rehabilitation is defined as a systematic functionally oriented intervention of therapeutic cognitive activities based on the assessment and understanding of patient's brain behavior deficits. This project focuses on restoring cognitive functions in order to understand the underlying deficits in the patient's brain by developing integrated cognitive rehabilitation scenarios in virtual reality that combine memory, attention and problem solving training with context specific motor movements.
