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.

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.
