Episode 284 - Dennis Sparta, PhD

On April 18, 2024 we spoke with Nancy Philp about the blood supply to the retina and the cells and membrane transporters that deliver glucose and lactate to photoreceptors and other cells for glycolytic and aerobic metabolism. Guest: Nancy Philp, Professor, Department of Pathology and Genomic Medicine, Sidney Kimmel Medical School, Thomas Jefferson University Participating: Erica Tatiana Camacho, Departments of Mathematics and Neuroscience, Developmental and Regenerative Biology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to James Tepper for original music

On April 4, 2024 we had a chance to talk to Kara Marshall about the membrane protein PIEZO2, which is responsible for sensory transduction of many of the mechanical senses, including light touch, vibration, and proprioception. We especially focused on its function in sensing internal pressure and movement, including bladder pressure and blood pressure. Guest: Kara Marshall, Assistant Professor, Department of Neuroscience and Howard Hughes Medical Institute, Baylor College of Medicine Participating: Lindsey Macpherson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to Jim Tepper for original music

On March 21, 2024, we spoke with Dennis Sparta on the complexity of brain circuitry and strategies for dissecting out the contributions of different brain areas engaged in reward and in alcohol use. Guest: Dennis Sparta, Assistant Professor, Department of Psychology, University of Illinois Chicago. Participating: Marina Silveria, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Matt Wanat, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to Jim Tepper for original music

On March 7, 2024, we were joined by Lynn Dobrunz to talk about brain circuits underlying anxiety and PTSD, and the role of neuropeptide Y modulation of glutamate transmission in the hippocampus and amygdala. Guest: Lynn Dobrunz, who is Professor and Chair of the Department of Anatomy and Neurobiology and Director of the Neuroscience Institute at the University of Tennessee Health Sciences Center, Memphis. Participating: Marina Silveria, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to James Tepper for original music

On February 29, 2024 we got to talk to Dwight Bergles about the cellular mechanism that generates spontaneous activity in auditory receptors before the onset of hearing, and the function of that activity in development of appropriate circuitry throughout the auditory pathway. Guest: Dwight Bergles,Professor in the Departments of Neuroscience, Biomedical Engineering, and Otolaryrngology-Head & Neck Surgery, and the Kavli Neuroscience Discovery Institute at Johns Hopkins University. Participating: Marina Silveria, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to Jim Tepper for original music

On February 22, 2024 we talked with Janko Gospocic about changes in gene expression associated with changes in social status in a fascinating species of ants. Guest: Janko Gospocic, Assistant professor, Department of Psychiatry and Green Center for Reproductive Biology Sciences at UT Southwestern University Participating: Lacy Barton, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Alexey Soshnev, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to James Tepper for original music.

On February 15, 2024 we talked with Yarimar Carrasquillo on acute and chronic pain, and the brain circuits responsible for self-maintaining pathological chronic pain. Guest: Yarimar Carrasquillo, Investigator, Section on Behavioral Neurocircuitry and Cellular Plasticity at the NIH National Center for Complementary and Integrative Health. Participating: Lindsey Macpherson,Department of Neuroscience, Developmental and Regenerative Biology, UTSA Matt Wanat, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to James Tepper for original music.

On February 8, 2024, we met with Josh Neunuebel, to discuss his work on ultrasonic vocalization during mouse social behavior. We discussed his method for experimental compilation of the range of socially used vocalizations, and determining their behavioral meanings. Guest: Josh Neunuebel, Associate Professor, Department of Psychological and Brain Sciences, University of Delaware. Participating: Alfonso Apicella, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Francesco Savelli, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Nicole Wicha, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to James Tepper for original music.

On February 1, 2024, Lori Holt joined us to talk about categorical perception of speech (and some other) sounds, how they are learned and the brain mechanisms responsible for them. Guest: Lori Holt, Professor of Psychology, University of Texas at Austin Participating: Nicole Wicha, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Marina Silveria, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Host Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA

On January 25, 2024 we spoke with Michael Long about vocalization, language and conversation from birds to humans. We discuss what can be learned from birdsong, warbling in parrots, singing mice, and human conversation. Guest: Michael Long, Thomas Suzanne Murphy Professor of Neuroscience and Physiology and Professor in the Department of Otolaryngology at the New York University School of Medicine. Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to James Tepper for original music.
