        Colleen A. Hanlon, PhD

  
SPEAKER BIO
An assistant professor in the departments of Psychiatry and Neurosciences at the Medical University of South Carolina, the overarching theme of Dr. Hanlon’s research interest includes imaging and harnessing the neuroplastic properties of the brain that lead to reorganization of function and response to injury. Recipient of a National Institute of Drug Addiction Outstanding Early Career Investigator award in 2011, Dr. Hanlon performed her doctoral research in the Department of Neurobiology at Duke University and did a postdoctoral fellowship with Dr. Linda Porrino in the Department of Physiology and Pharmacology at Wake Forest University School of Medicine.

Her doctoral research at Duke University involved functional neuroimaging of cortical-striatal plasticity that occurs in the first few months following a stroke. Here she became interested in fronto-striatal dopamine systems that guide behavior, which led to postdoctoral studies in the Center for the Neurobiology of Addictive Disorders at Wake Forest University.

Dr. Hanlon’s primary area of research is in addiction. Through her appointment in the Brain Stimulation division and as a faculty member of the Center for Biomedical Imaging, she is currently using functional and structural brain imaging techniques, along with transcranial magnetic stimulation, to investigate cortico-striatal connectivity in chronic cocaine users. She is also involved in several projects that involve quanitification of aberrant neural circuitry in opiate dependence, nicotine dependence, post-traumatic stress disorder, chronic stroke patients, and most recently Tourette Syndrome.
  
      OBJECTIVES                                                                                                                                                               
       At the completion of this session, the participant will be able to:
       

1.  Explain how interleaved TMS/MRI allows us to probe cortical and subcortical activity.
2.  Describe the medial and lateral frontal-striatal systems and their relevance to reward and control behaviors.
3.  Discuss how brain stimulation techniques such as TMS are able to selectively increase or decrease activity in those circuits.
