She is a professionally trained improvisational and comedic actress who studied and performed at The Groundlings and ImprovOlympic. [3] Unlike blood passing from the capillaries into the choroid plexus, the epithelial cells lining the choroid plexus contain tight junctions between cells, which act to prevent most substances flowing freely into CSF.
