Network simulations of selfsustained activity in networks of adaptive exponential integrate and fire neurons
=============================================================================================================
Demo files implemented using both NEURON and PyNN. The top level
folder (the folder with this README) python files will work with PyNN
version 0.8 and the python files in the prevPyNN subfolder will work
with PyNN version 0.7
demo_cxlts

Simulations of selfsustained AI states in a small N=500 network of
excitatory and inhibitory neurons, described by Adaptive
Exponential (BretteGerstnerIzhikevich) type neurons with
exponential approach to threshold. The connectivity is random and
there is a small proportion (5%) of LTS cells among the excitatory
neurons. This simulation reproduces Fig. 7 of the paper below.
demo_cx_updown

Simulations of UpDown states in a twolayer cortical network, with
one N=2000 network and a smaller N=500 network. Both networks have
excitatory and inhibitory neurons described by Adaptative
Exponential (BretteGerstnerIzhikevich) type neurons with
exponential approach to threshold. The connectivity is random
within each network as well as between them. In the N=500 network,
there is a small proportion (5%) of LTS cells among the excitatory
neurons. This simulation reproduces Fig. 13 of the paper below.
