Nov 18, 2020 · Kimberley McAllister has been fascinated by the human brain since college. As a graduate student in the 1990s studying developmental neurobiology, she was drawn to the question of how the brain is built: how individual brain cells in a growing fetus somehow organize themselves into an organ capable one day of pondering the mysteries of life. Elucidating brain cell type specific gene expression patterns is critical towards a better understanding of how cell-cell communications may influence brain functions and dysfunctions. We set out ...
The brain is the central organ of the human nervous system, and with Normal brain function relies on a diverse set of differentiated cell types, including neurons, glia, and vasculature.
