On March 26, 2026, we held our annual UTSA Neuroscience Symposium entitled "From Place Cells to Cognition", featuring 5 speakers presenting original research on the cognitive functions of hippocampal place cells. They discussed the firing patterns of place cells during exploration of cognitive maps, anticipating future movements, recall of previously visited locations, and imagining the movement of objects in the environment. After the symposium, I met with the speakers to review some of the themes that emerged throughout the day. Speakers: Francesco Savelli, Assistant Professor, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Annabelle Singer, Associate Professor, Department of Biomedical Engineering, Georgia Institute of Technology and Emory University Albert Lee, Associate Professor, Department of Neurology and Howard Hughes Medical Institute, Harvard University Jill Leutgeb, Professor, Department of Neurobiology, University of California San Diego Kamran Diba, Associate Professor, Department of Anesthesiology, University of Michigan Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to James Tepper for original music

On March 19, 2026 we spoke with Dr. Se-Woong Park about the idea that many of the symptoms of Autism may arise from changes in brain mechanisms that allow us to predict events in the near future from those in the recent past. Topics included internal predictions of postural destabilization produced by our own movements, and prediction of the trajectories of moving objects. We discussed some experimental results testing this idea.

On December 8, 2025 we spoke with Dr. Matthew Goodwin about the use of wearable biosensor technology and machine learning to improve behavioral evaluation of autism, to provide real time alerts for caregivers and more effective interventions before the onset of potentially dangerous behavioral situations. Guest: Matthew Goodwin, Professor and Associate Chair of Research at the Department of Public Health and Health Sciences and the Khouri College of Computer Sciences, at Northeastern University. Participating: Leslie Neeley, Director of the Child and Adolescent Policy Research Institute, and Associate Director of the Brain Health Consortium, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to James Tepper for original music

On December 4, 2025 we talked with Dr. Mike Beckstead about his work on changes in dopaminergic neuron excitability in the ventral tegmental area in an animal model of Alzheimer's disease. Mike explained the molecular mechanism of the excitability change and the change in gene expression at its cause. Guest: Mike Beckstead, Professor and Hille Family Foundation Chair in Neurodegenerative Disease Research, Aging & Metabolism Research Program Oklahoma Medical Research Foundation Participating: 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 November 20, 2025 we met with Dr. Cristian Lasagna-Reeves to talk about tau protein, its normal function, and what is known about how it aggregates to form the tangles seen in a variety of neurodegenerative brain conditions. We discussed the problem of determining whether the aggregates were causes or effects of the disease process, and whether reducing expression of tau might be an effective treatment. Guest: Cristian Lasagna-Reeves, Associate Professor, Dept. of Neurology, Baylor College of Medicine Participating: George Perry, Department of Neuroscience, Developmental and Regenerative Biology, UT San Antonio Hyoung-gon Lee, Department of Neuroscience, Developmental and Regenerative Biology, UT San Antonio Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UT San Antonio Thanks to Jim Tepper for original music

On November 13, 2025, we met with Dr. Maria Diehl, to learn about her experiments on avoidance learning in rats. The conversation focused on learning in a social context, in which one animal benefits from watching another learn the task. We had to relocate this week, because of a noisy construction project in the hallway outside our usual room. Guest: Maria Diehl, Associate Professor in Psychological Science, Kansas State University. Participating: Tony Burgos-Robles, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Itamar Lerner, Department of Psychology, UTSA Host: Charles Wilson, Department of Neuroscience, Developmental and Regenerative Biology, UTSA Thanks to Jim Tepper for original music

On November 6, 2025, I spoke with Dr. Jason O'Connor about the behavioral and psychological effects of inflammation, and their similarity to depression. Jason explained how inflammation can produce those symptoms by increasing levels of kynurenine and metabolites in the brain. We discussed the possibility that depression may sometimes result from a rise in those metabolites in the absence of inflammation. Guest: Jason O'Connor, Associate Professor of Pharmacology at the UT San Antonio Long School of Medicine and the Audie Murphy VA Hospital.
