Pełny opis

Population Density Methods (PDM) have gained§prominence in recent §years in Theoretical Neuroscience as an analytical§and time-saving §computational tool. The method involves solving a§density equation §(aka, Fokker-Planck) instead of simulating many§individual neurons. §Simplifying assumptions of the underlying neuron§model are often §made so that the resulting PDM equations have low§dimension for §tractability. Thus, dimension reduction techniques§are vital for §physiological modeling. An introduction to PDM and §the relevant issues are discussed in Chapter 2. A§''moment closure'' §dimension reduction technique is analyzed in Chapter§3. We show §the §equations are §ill-posed in the fluctuation-driven regime with§realistic parameters §despite several contrary reports in the literature. §The dimension §reduction §method is even worse for the more physiological§''theta'' model §(Chapter 4). A robust and accurate alternative§reduction technique §using a moving eigenvector basis is developed and§implemented in §Chapter 5. The stochastic firing rate dynamics of§various neural §models are analyzed in Chapter 6 with the tools we§have developed.
