Neuron Pool

Imagine you have a similar with three kinds of neurons with different ion channels present in different parts of the cell:

filepath="/path/to/file/cell.asc"
blank_neuron=instantiate(filepath)
set_nsegs!(blank_neuron)
myneuron1=add(blank_neuron,HH())
myneuron2=add(blank_neuron,(HH(),Passive()))
myneuron3=add(blank_neuron,(HH(),Passive()),(HH(),Passive()),Passive(),Passive());

You could easily construct an array of the neurons above to be accessed during simulations:

my_neur_array=Array(Neuron,3)
my_neur_array[1]=myneuron1
my_neur_array[2]=myneuron2
my_neur_array[3]=myneuron3

But this is actually inefficient, because the methods used for solving the equation in the first one are different than the second, which are different than the third because each has different channel types: consequently, the compiler has to figure out which ones to use.

Consequently, you see above that the Network type contains a “Neuron Pool” which for the case above would look like this:

type NeuronPool0
        N_1::Array{Neuron_1,1}
        N_2::Array{Neuron_2,1}
        N_3::Array{Neuron_3,1}
end
