This model produces the hippocampal CA3 neural network model used in the paper below. It has two modes of operation, a default mode and a circadian mode. In the circadian mode, parameters are swept through a range of values. This model can be quite easily adapted to produce theta and gamma oscillations, as certain parameter sweeps will reveal (see Figures). BASH scripts interact with GENESIS 2.3 to implement parameter sweeps. The model contains four cell types derived from prior papers. CA3 pyramidal are derived from Traub et al (1991); Basket, stratum oriens (O-LM), and Medial Septal GABAergic (MSG) interneurons are taken from Hajos et al (2004).

Overview
--------

GENESIS 2.3 Code for Hippocampal CA3 Circadian Model.

This model produces the hippocampal CA3 neural network
model used in the paper below. It has two modes of operation, a
default mode and a circadian mode. In the circadian mode, parameters
are swept through a range of values.

This model can be quite easily adapted to produce theta and gamma
oscillations, as certain parameter sweeps will reveal (see
Figures). BASH scripts interact with GENESIS 2.3 to implement
parameter sweeps.

The model contains four cell types derived from prior papers. CA3
pyramidal are derived from Traub et al (1991); Basket, stratum oriens
(O-LM), and Medial Septal GABAergic (MSG) interneurons are taken from
Hajos et al (2004).

Running the default model:
----------------
1. Unzip the downloaded file (if necessary)
2. Make sure that the genesis binary is in your current path
3. Change directory into `simfiles` and type `genesis main_default.g`
4. Data analysis scripts are located in `matlab_plotting/extract_data`.
The file `analyse_script.m` will automatically load and plot simulation
data in Matlab.

Running the circadian model
------------------
The simfiles folder also contains a script called `ssh_script.sh`. This
is used for setting up batch simulations to conduct parameter sweeps.
Some parameters in the model depend on time (see Methods, Stanley 2013)
this script enables one to sweep through different times of day.

To implement a default run, type `./ssh_script.sh 0`

For additional help customizing the model and automatic processing of
batch simulations, please contact the authors.
