Graphical simulation of early development of the cerebral cortex.
Much experimental data exists concerning the development of the cerebral cortex. There is a need for a common vehicle to integrate this data and to allow the testing of hypotheses concerning development. Computer simulation and visualization are powerful mechanisms for hypothesis testing. Our long-term goal is to create a robust, extensible, portable tool for simulation and visualization of cortical development to serve both research and educational purposes. This paper describes a simulation program, SimCortex, which models the early stages of development of the cerebral cortex of the mouse. Version 1.0 of SimCortex models the proliferation of progenitor cells in the pseudostratified ventricular epithelium (PVE), the generation of young neurons and their migration into the cortical plate, which is the forerunner of cell layers II through VI of the adult cortex. We present an overview of the design and implementation of SimCortex, sample output of the system and a comparison of our results with experimental data. We conclude with a brief overview of proposed future enhancements of the system.
