We study the quasineutral limit of the isothermal Euler-Poisson system describing a plasma made of ions and massless electrons. The analysis is achieved in a domain of R and thus extends former results by Cordier and Grenier [Comm. Partial Differential Equations, 25 (2000), pp. 1099–1113], who dealt with the same problem in a one-dimensional domain without boundary.

Kaschube et al. (Reports, 19 November 2010, p. 1113) argue that pinwheel density in three mammalian species follows a universal constant of π as predicted by their orientation-selective suppressive long-range connectivity model. We dispute their conclusions and suggest that a simple brain size-pinwheel density scaling law suffices in predicting the self-organized and disorganized orientation ma...
