Marcel Adam Just, the D.O. Hebb Professor of Cognitive Neuroscience at Carnegie
Mellon and Director of its Center for Cognitive Brain Imaging, is a researcher and
scientific contributor in a broad set of areas of neuroscience. His research uses brain
imaging (fMRI) in high-level cognitive tasks to study the neural basis of the
architecture of human thought. The fMRI studies attempt to determine the underlying
cortical components of the cognitive system and the nature of the collaboration among
them in many different types of tasks. The individual projects investigate high level
thinking in tasks like sentence comprehension, mental rotation, imagery, object
recognition, problem-solving, and decision-making. The projects examine normal cognitive
functioning in college students and in adolescents, as well as in special populations,
such as patients with autism and children with dyslexia.
