On September 10, 2026 we talked with Dr. Melissa Caras on the neurophysiology underlying perceptual learning in the auditory cortex. She defined perceptual learning, explained how it can be measured in animals, and described the changes in neuronal activity auditory cortex neurons associated with learning.

On April 23, 2026 I met with Drs. Vanesa Nieto Estévez and Parul Varma to talk about brain organoids made from cells derived from patients with genetic childhood epilepsy. Vanesa and Parul explained how these patient-derived tissue cultures are used to isolate the defects in brain development that underly the brain disorder, and to suggest and test potential treatments.

On April 9, 2026 I spoke with Dr. Marcelo Marucho, on the electrical properties of actin filaments and microtubules, ubiquitous components of the cytoskeleton of nearly all cells. He explained how the surface charge of these proteins creates a thin charged layer in the adjacent cytoplasm in which electrical signals may be generated and conducted. In the case of microtubules, the interaction between external and luminal surfaces can produce oscillations. We discussed some of the possible functions of these electrical signals in the brain.

On April 2, 2026 we met with Dr. Daniel Llano to discuss the organization of the largest subcortical auditory brain structure, the inferior colliculus. He told us about the three major subnuclei within the inferior colliculus, their synaptic connections with other auditory and somatosensory structures, and the problems encountered as we try to identify the cell types and local connectivity within the nucleus.

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.

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
