Dr. Coslett is Professor of Neurology at the University of Pennsylvania and a long-time consultant to the Moss Rehabilitation Research Institute. He is trained in Neurology with specialization in Behavioral Neurology. He has received funding from the NINDS, NIMH, NIDCD and private foundations for his research.

Areas of Expertise

• Visuo-spatial attention including Neglect and the Balint syndromes. Areas of interest include the cognitive neuropsychology of attention, mechanisms underlying clinical disorders such as neglect and treatment of neglect and related disorders.
• Normal and abnormal processing of temporal information. We are investigating the brain mechanisms and anatomic basis of the perception of time in normal and clinical populations. Methodologies include Transcranial Magnetic Stimulation, fMRI and behavioral studies in normal and brain lesion subjects.
• Role of TMS in the treatment of chronic aphasia. This on-going investigation explores the use of 1 Hz. Repetitive TMS over the right hemisphere as a treatment for aphasia resulting from strokes. The anatomic basis of the improvement is also assessed with fMRI.
• Motor control and its breakdown in brain lesions. This line of research explores the anatomic basis and functional architecture of the motor control system using behavioral studies in normal and brain lesion subjects.

Programs of Research

• TMS in the treatment of chronic aphasia
• Behavioral studies of the architecture and anatomic bases of motor control
• fMRI, TMS and behavioral investigations of normal and abnormal time processing
• Investigations of the anatomic basis of aphasia using developing techniques in voxel-based morphometry
• Mental motor imagery as a measure of pain severity
