Neuroscience Futures Seminar Series

A collage of junior scientists and clinician-scientists hard at work

Spotlighting junior scientists and clinician-scientists

The Department of Neurology in the Oregon Health & Science University School of Medicine and the OHSU Brain Institute co-sponsor this lecture series which is designed to spotlight junior scientists and clinician-scientists. The seminar series that originated in the fall of 2021 is designed with three broad goals in mind:

  • Engage neurology and neuroscience researchers from minoritized groups to promote a more diverse future.
  • Provide a platform for junior scientists and clinician-researchers to showcase their work and network with the local neuroscience community.
  • Promote an action-oriented effort to increase diversity in the national and international academic community.

Thalamo-striatal projections encoding motivated behavior
Sofia Beas, Ph.D.,
 Assistant Professor, Neurobiology, University of Alabama at Birmingham

How motivational states drive actions to achieve goals is a fundamental question in neuroscience. However, this remains unclear despite extensive research on the role of the mesocorticolimbic systems orchestrating goal pursuits. We previously identified the paraventricular nucleus of the thalamus (PVT), especially its projections to the nucleus accumbens (NAc), as essential for instrumental behaviors. However, the precise role of this thalamo-striatal pathway in goal-oriented behaviors has been debated. Here, we characterize two distinct neuronal subpopulations in the PVT, termed Type1PVT and Type2PVT, which differ in their genetic identity, functionality, and connections. We reveal that these subpopulations form parallel thalamo-striatal pathways that encode different components of motivated behavior.

Dr. Sofia Beas is an Assistant Professor at the University of Alabama, Birmingham. The overall mission of her laboratory centers on increasing our understanding of the neural mechanisms underlying motivated behavior and identifying how these processes can be dysregulated in neuropsychiatric disorders. Dr. Beas first attained a Ph.D. in Neuroscience from the University of Florida. She then pursued a postdoctoral fellowship in the Unit on Neurobiology of Affective Behaviors at the National Institute of Mental Health (NIMH).

Behaviors and neural circuits for pleasure and pain in mice (password 32MjgYvS)
Ishmail Abdus-Saboor, Ph.D., Assistant Professor, Biological Sciences, Zuckerman Mind Brain Behavior Institute, Columbia University

The Abdus-Saboor lab wants to understand how the brain generates the perception of pain and pleasure based on sensory stimuli applied to the skin. Working in mice and naked mole-rats, they are integrating the peripheral and central nervous systems, seeking to uncover genes and neural circuits for somatosensation from the skin to the spinal cord and brain.

Dr. Abdus-Saboor received his Ph.D. in Cell and Molecular Biology at the University of Pennsylvania with Meera Sundaram. Following training in developmental genetics, he moved into sensory neuroscience as a postdoc at Cornell and back at the University of Pennsylvania, with Benjamin Shykind and Wenqin Luo, respectively. Ishmail has received many honors including an NIH K99/R00 Pathway to Independence Award and Burroughs Wellcome Fund PDEP Fellowship as a postdoc. Since opening his lab, he has been named a Rita Allen Foundation Scholar, Alfred P. Sloan Foundation Fellow, Pew Biomedical Scholar, and a recipient of the NIH DP2 New Innovator Award and Chan Zuckerberg Initiative Science Diversity Leadership Award.

Elucidating the Mechanism underlying Stress and Caffeine-Induced Motor Dysfunction using a Mouse Model of Episodic Ataxia Type 2 (password mGJe5smE)
Heather Snell, Ph.D., Associate Researcher, Department of Neuroscience, Albert Einstein College of Medicine

Dr. Heather Snell completed her undergraduate degrees in Biochemistry and English literature at Louisiana State University. She then returned home to Fort Worth, Texas, to complete her Ph.D. at the University of North Texas Health Science Center in the laboratory of Dr. Eric B. Gonzales. Her work combined cellular biology with pharmacology, receptor modeling, and whole cell electrophysiology to investigate the interactions of the GABAA ρ1 receptor with a class of drugs called guainidine compounds which block acid sensing ion channels (ASICS). Her current work, first as a Postdoctoral Fellow and now as an Associate Researcher at Albert Einstein College of Medicine in the laboratory of Dr. Kamran Khodakhah, focuses on understanding the receptors and channels underlying the intrinsic activity of the GABAergic cerebellar Purkinje cells in health, but also in cerebellar disorders, such as the most common form of Episodic Ataxia, Episodic Ataxia Type 2 (EA2).

Neurodevelopment in Autism and Related Childhood Disorders: From Genes to Complex Phenotypes (password pNRRaph5)
Leanna Hernandez, Ph.D., Postdoctoral Fellow, Department of Psychiatry and Biobehavioral Sciences, UCLA

Neurodevelopmental disorders, including autism and schizophrenia, are etiologically complex and characterized by diverse clinical and neurobiological features. This intrinsic heterogeneity makes it very challenging to identify early biomarkers of disease risk and develop targeted treatments. In this talk, Leanna Hernandez, Ph.D., presented her work using a genetics-first approach to 1) parse neurobiological heterogeneity in autism and related childhood disorders, 2) understand the shared genetic etiology between co-occurring conditions, and 3) identify early brain-based biomarkers of risk for future psychiatric symptoms.
