Dr. Crosson received his Ph.D. in Psychology from Texas Tech University in 1978. He has studied language and aphasia for over 20 years. His work in subcortical structures in language has been internationally recognized since the 1980’s. Over the past eight years, he and his laboratory have been involved in imaging the neural substrates of language and semantics using functional magnetic resonance imaging (fMRI). Studies from his laboratory have investigated inter-individual variability in the functional neuroanatomy of language, the neural substrates of semantic memory, structures involved in verbal working memory, and the role of the basal ganglia in language generation. More recently, he has become involved in studies of neuroplasticity, both developing a new treatment for intention in aphasia and developing the fMRI techniques to image its neural substrates. His laboratory has tackled many problems involved with the fMRI of overt language production in aphasia rehabilitation, including the reduction of motion-related signal changes and equating across different sessions for variable sensitivity to brain activity. In the last year, he has lectured on the neuroplasticity of language rehabilitation in Australia, Germany, and the United States. Recently, he was appointed as an Honorary Professor at the University of Queensland in Brisbane, Australia. He has served on the senior editorial board of the Journal of the International Neuropsychological Society for the past five years, first as an Associate Editor, then as Editor for Critical Reviews and Dialogues. He just completed three years of service on the Board of Directors of the International Neuropsychological Society, and served on the Board of Directors for the American Board of Clinical Neuropsychology, Board of Directors (1996-2001). He holds a Research Career Scientist Award from the Department of Veterans Affairs Rehabilitation Research and Development Service, and was a University of Florida Research Foundation Professor (2000-2003). Dr. Crosson is a Fellow of the American Psychological Association (Division of Clinical Neuropsychology). Recently, he chaired the Task Force for Human and Large Animal Imaging for the Advanced Magnetic Resonance Imaging and Spectroscopy facility at the University of Florida.
Dr. Crosson’s current research interests include subcortical functions in language, individual variability in the functional neuroanatomy of language, the neural substrates of semantic memory, and neuroplasticity in aphasia rehabilitation.
Dr. Crosson participates in practicum supervision in the neuropsychological assessment in stroke. The emphasis in this practicum is on understanding lesion location and vascular dynamics and their relationship to cognitive functions after stroke.
