Modeling Currents About Vitellogenic Oocytes of the Cockroach, Blattella germanica.

An insect oocyte with a disc-shaped sink of current on its ventral surface during a vitellogenic phase of development is used to demonstrate modeling of expected currents arising from a mathematically defined source. A simple model with an analytical solution for the expected currents is compared to a more complex model in which expectations are computed by mathematical integration. The currents about two oocytes of different pattern type are interpreted in light of the two models.
