On May 2, 2024 we spoke with Skirmantas Janusonis on the peculiar morphology and spatial distribution of the serotonin innervation of the brain, and his idea that it can be described using the mathematics of fractional Brownian motion. We consider the kind of developmental mechanisms that could be responsible.



Guest:

Skirmantas Janusonis, Associate Professor, Department of Psychological and Brain Sciences, University of California, Santa Barbara.

Participating:

Fidel Santamaria, Department of Neuroscience, Developmental and Regenerative Biology, UTSA

On April 25, 2024, we met with the 5 speakers for this year's Annual Neuroscience Symposium at UTSA to discuss epigenetics and nervous system development. We discussed the best known molecular mechanisms that control patterns of gene expression and current limitations faced in studies of those mechanisms. We also discussed the promise of epigenetics to explain the differentiation of nervous system cell types, mechanisms of developmental, neuropsychiatric and neurodegenerative disorders.

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

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

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.

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.
