Izhikevich neuron in c++

This is some c++ code to simulate Izhikevich spiking neurons, from the paper:

How to run it

For easier building there is a docker image

Build the docker:

docker build -t izhi .

Start the docker interactively with this (project) folder shared under /izhi for easy development:

docker run --name izhi -v `pwd`:/izhi -it izhi /bin/bash

(I dont know how pwd works on windows, but it's the absolute path to this folder on your computer)

Build the source code (in the interactive docker):

cd /izhi
mkdir build
cd build
cmake ..
make
./izhikevich

Output image will be in output/out.jpg

Some presets

Regular spiking:
./izhikevich 0.02 0.2 -65 8

Intrinsically bursting:
./izhikevich 0.02 0.2 -55 4

Chattering:
./izhikevich 0.02 0.2 -50 2

Fast spiking:
./izhikevich 0.1 0.2 -65 2

Thalamo-cortical:
./izhikevich 0.02 0.25 -65 0.05

Resonator:
./izhikevich 0.1 0.26 -65 2

Low-threshold spiking:
./izhikevich 0.02 0.25 -65 2 

TODO

The fixed DC input drive does not have the correct value for all neuron simulations, for now the easiest way is to change it manually in the "step" loop in the code.
