Project Description
Modeling the PFC-Accumbens Glutamatatergic Pathway in Cocaine.

Computational model of glutamate dynamics in the PFC-NAC perisynaptic space
A computational framework will be developed to study glutamate homeostasis in the perisynaptic space of a prefrontal-accumbal glutamatergic synapse including mechanisms such as synaptic glutamate release, its diffusion into the extracellular space, and its removal via transporters. Different from previous models, extracellular glutamate produced by exchangers is included and its effect on Glu homeostasis is investigated. The framework is then used to iteratively determine feasible geometries for the glial sheath configurations surrounding the synapse, by matching predictions with experimental data, and ensuring Glu homeostasis, using known ranges for parameter values. Our emphasis is on establishing an overall framework within which the role of many distinct glial interactions can be evaluated with a two-pool transmitter model, and in developing systematic approaches to study the adequacy of different models accounting for a wide range of biological data.
