Galvan/Wichmann Lab

Adriana Galvan, Ph.D.
Lead scientist, Project 2: Parkinsonism-Related Changes in Activity of Cortical Projection Neurons in Monkeys
Director, Core B: Research Services Core

Adriana GalvanAdriana Galvan received her PhD in Neurosciences from the Center of Research and Advanced Studies, National Polytechnic Institute, Mexico City, Mexico. She joined the labs of Drs. Smith and Wichmann in 2000, as a post-doc fellow, to study localization and functions of GABA receptors in monkeys. In 2009 she joined the Department of Neurology as junior faculty member.  Her research focuses on understanding neural transmission in the basal ganglia, both in normal and pathological conditions, using a variety of in vivo methodologies that include extracellular electrophysiological recordings, electrical stimulation, intracerebral microinjections, microdialysis and optogenetic technique.

Thomas Wichmann, M.D.
Director of the Emory Udall Center
Key scientist, Project 2: Parkinsonism-Related Changes in Activity of Cortical Projection Neurons in Monkeys

WichmannDr. Wichmann attended medical school in Freiburg (Germany) and received his medical degree in 1984.  This was followed by postdoctoral medical and research training in Germany and at Johns Hopkins University (Baltimore, MD), and internship and Neurology residency training at Emory University (Atlanta, GA).  He has been a member of the movement disorder division in the Dept. of Neurology at Emory University since 1996.  He is currently a Professor of Neurology, and serves as the Associate Director of the movement disorder clinic at Emory.  His research focuses on electrophysiological and morphological changes in Parkinson’s disease, with the aim of developing new pharmacological or surgical interventions to help parkinsonian patients.

Dr. Hu received an MD degree from Jiao Tong University (Shanghai, China), followed by residency training at RenJi Hospital, and work as an Assistant Professor in Gerontology (Dept. Medicine) at the same institution.  She came to the US in 2000, first working as a research lab trainee in an FDA laboratory in Mobile, Alabama, and later in research laboratories at Emory University (Dept. Pathology) and Morehouse University (Microarray Core Facility, Cardiovascular Research Institute).  She joined the Wichmann lab as a highly skilled research specialist in 2006.  She is experienced with electrophysiology as well as immunohistochemistry and electron microscopy.  Click here for Dr. Hu's recent publications.

Anne-Caroline Martel

Damien Pittard

Dr. Martel received her PhD in neurosciences from Aix Marseille University, France, in December 2019. She joined the Wichmann lab in February 2020 as a Postdoctoral Fellow. Her current research focus on the subthalamic nucleus, a key component of the basal ganglia circuit. The study aims to understand the temporal relationship between the emergence of Parkinson signs and the structural and functional integrity of the cortico- and pallido-subthalamic projections using functional and anatomic comparisons in motor asymptomatic and motor symptomatic MPTP-treated monkey. By employing optogenetic tools and in vivo electrophysiological recordings she will assess responses of STN neurons to optogenetic activation of cortical and external pallidal inputs, as well as emerging changes in STN neuronal in normal and parkinsonian states. These studies are combined with postmortem light and EM and 3D-EM reconstructions using tissue from normal and parkinsonian monkeys, to assess the number, localization, and ultrastructure of glutamatergic cortical terminals and GABAergic pallidal terminals in the STN.
