Extending the Hodgkin Huxley Model

• I think the models that come with PyNN and Nest (as of October 22) only deal leak, sodium, and potassium.
• Mammalian neurons also make a lot of use of calcium.
• Hodgkin and Huxley worked with giant squid neurons, which are pretty big, so they could look at them with an optical microscope.
• Trappenberg talks about the Wilson model. I got "Simplified dynamics of human and mammalian neocortical neurons" 1999 H. Wilson, which seems to talk about a fair few things Trappenberg talks about.
• So, the Wilson model, like the Izhikevich point model can account for the wide variety of spiking behaviour of mammalian neurons.
• I didn't know that fast spiking neurons worked up to 800hz.
• Note, I think of neurons firing every x ms. So, a typical pyramidal neuron won't typically fire more than once every 10 ms. Lots of other folks think of it in hertz. Every 10ms is 100 hz.
