Dopaminergic (DA) neuron model with a morphologicaly realistic
dendritic architecture. The model captures several salient features of
DA neurons under several pharmacological manipulations and exhibits
depolarization block for sufficiently high current pulses into the

The model refers to the paper:

Anna Y. Kuznetsova, Marco A. Huertas, Alexey S. Kuznetsov, Carlos
A. Paladini and Carmen C. Canavier (2010) Regulation of firing
frequency in a computational model of a midbrain dopaminergic neuron
J Comput Neurosci. 2010 Jun;28(3):389-403.

The files included here correspond to the morphologically realistic
reconstructed model (see Figure 1 in paper) and reproduce results
presented in the paper:
1) Fig2a2.hoc			Figure 2 (a2)
2) Fig2b2.hoc			Figure 2 (b2)
3) Fig2f2.hoc				Figure 2 (f2)
4) Fig6a_solid_trace            Figure 6a: solid line corresponding to
                                100 pA stimulation current
5) Fig6a_dashed-line_trace      Figure 6a: dashed line corresponding
                                to 500 pA stimulation current

The first three examples illustrate spontaneous firing of the model DA
neuron in control (1) and after blocking SK channel (2) and Na
channels (3).

Last two files show the response of the model DA neuron to simulated
current pulse to the soma for 100 pA (4) and 500 pA (5). In the last
case one can observe depolarization block.

You can run the simulation either by auto-launching from ModelDB, or
by first compiling the mechanisms as follows:

a) Under LINUX


	Then type 

	nrngui mosinit.hoc

b) Under Windows

	Run mknrndll to compile the mod files in the top level

c) Under MAC - OS X

	Drag and drop the archive file on the mknrndll icon (in the
	NEURON application folder).

If running the individual files listed above:
Once Neuron has been started on your platform select in the main manu
	Tools -> RunControl
	Graph -> Voltage axis
then select 
	File -> load hoc
and choose the file you want to run. Finally press Init & Run.

If auto-launched then press a button corresponding to the figure
desired and you can generate figures like these:
