This is the readme for a model used in the paper

Morse TM, Carnevale NT, Mutalik PG, Migliore M, Shepherd GM (2010)
Abnormal excitability of oblique dendrites implicated in early
Alzheimer's: a computational study Front. Neural Circuits 4:16

The model code was contributed by Tom Morse.  It was created (see
paper for details) from earlier models (especially Migliore et
al. 2005 and calcium channels from Hemond et al. 2008) with
modifications and additions by Tom Morse and Ted Carnevale with
interaction with the other authors. It requires the NEURON simulator
to be installed (available at

To recreate figures from the paper, start the simulator by
auto-launching from ModelDB *OR*

Under unix systems:
In the expanded archive's folder compile the mod files using the
command "nrnivmodl"
run the simulation with the command "nrngui mosinit.hoc"

Under Windows systems:
Compile the mod files using the "mknrndll" program.
A double click on the simulation file
will open the simulation window.

Under MAC OS X:
drag and drop the expanded archive's folder onto the mknrndll icon.
drag and drop the mosinit.hoc file onto the nrngui icon.

Once the simulation is started click on a button to recreate a figure
from the paper, e.g.:

Figure 1,2 generates Figure 1B and 2 simultaneously:
(the simulation part is Figure 1B right hand side traces):
