Brian Grayson Rash, PhD

Associate Research Scientist in Neuroscience


The primary goal of my research is to investigate the cellular, genetic, and environmental mechanisms of cognitive neurodevelopmental disorders. The environmental component of this risk is prominent during embryonic development, and is key to our understanding of avoidable risks to brain development. I utilize a wide variety of approaches including state-of-the-art optogenetic and computational methods to study how cortical stem cells, known as radial glial cells (RGCs), proliferate and differentiate into post-mitotic neurons. We are uncovering key subcellular dynamics of RGCs which are important for cortical growth and circuit formation (see Rash BG et al., 2016, Science Advances). Current research aims to determine the subcellular calcium dynamics of RGCs, their relation to mitochondrial and cytoskeletal activity, and how this regulates fundamental processes in cerebral cortex development, such as neurogenesis and the migration of newborn neurons out of the stem cell niche. Understanding how these processes can be disrupted by environmental/maternal factors, including metabolic disorders and the usage of medications or other drugs during pregnancy, will be important in the prevention of childhood neurological disorders.
