    • About

    Dr. Bohnen is professor of Radiology and Neurology at the University of Michigan. He attended medical school in the Netherlands and completed a PhD in neuropsychology. He completed residency training in neurology (Mayo Clinic, Rochester, MN) and nuclear medicine (University of Michigan, Ann Arbor, MI). He was a fellow in movement disorders at the University of Michigan Medical Center. He holds clinical appointments in the Departments of Radiology (Division of Nuclear Medicine), Neurology at the University of Michigan, and the Ann Arbor VA (movement and cognitive disorders clinic). Dr. Bohnen’s research interests include the use of PET and MRI in the study of neurodegenerative disorders and normal aging. He is the director of the UM Functional Neuroimaging, Cognitive and Mobility Laboratory where his clinical research has a focus on neurobiological correlates of cognition, vestibular and multisensory processing during gait and postural control, olfaction and mobility in normal aging and in Parkinson disease.

    Research Overview

    The Functional Neuroimaging, Cognitive, and Mobility (FNiCoMo) Laboratory is part of the Departments of Radiology and Neurology at the University of Michigan. The mission of this lab is to gain a better understanding of how the architecture of the brain and functional processes in the brain (obtained with functional neuroimaging) determine cognitive functioning and mobility both in patients with neurodegenerative diseases (such as Parkinson's Disease) and in normal aging.
