This is a model of a multistage network with stages representing regions and synaptic contacts from the olfactory cortex to region CA1 of the hippocampus in Brian2 spiking neural network simulator. It is primarily designed to assess how syanptic facilitation at multiple stages in response to theta firing changes the output of the network. Further developments will be posted at: github.com/cdcox/multistage_network It is published in the paper "Pronounced differences in signal processing and synaptic plasticity between piriform-hippocampal network stages: A prominent role for adenosine". Brian H. Trieu, Eniko A. Kramar, Conor D. Cox, Yousheng Jia, Weisheng Wang, Christine M. Gall, and Gary Lynch Journal of Physiology 2015. This model was prepared by Conor D Cox University of California, Irvine For questions please contact Conor at cdcox1@gmail.com What it contains: 1. The model from the paper in a .py file 2. A csv containing the facilitaiton at each point in response to theta pulsing. How to use: 1. Unpack the model file and the csv. 2. Run the model, it should generate a figure similar (but not identical as connections randomize each run) to figure 9 in the above mentioned paper. 3. synapse_monitor can be used to probe state of individual synapses throughout firing train. 4. cell_monitor can be used to monitor region specific spiking.
