CA1 pyramidal neuron dendritic spine with plasticity (O`Donnell et al. 2011)

Accession: 144463

Biophysical model of a dendritic spine and adjacent dendrite with synapse. Model parameters adjusted to fit CA3-CA1 Shaffer collateral synapse data from literature. Model includes both electrical and Ca2+ dynamics, including AMPARs, NMDARs, 4 types of CaV channel, and leak conductance. Spine and synapse are plastic according to Ca2+ dependent rule. The aim of the model is to explore the effects of dendritic spine structural plasticity on the rules of synaptic plasticity.

spinemodel_fig6.m

spineodes.m

Matlab files to generate figure 6 from O'Donnell et al, J Neurosci, 2011.

Code simulates 3-compartment model: dendritic spine head, dendritic
spine neck, and adjoining dendritic branch. Simulation includes both
electrical and Ca2+ dynamics. See O'Donnell et al paper Methods
section and Figure 6 for further details.

Included are two files:
- spinemodel_fig6.m specifies all model and simulation parameters, calls
  spineodes.m, solves differential equations using a Matlab ODE solver,
  and plots figures.
- spineodes.m specifies system ODEs for use by spinemodel_fig6.m.

To try a basic simulation, simply run spinemodel_fig6.m as is from Matlab.

To vary model parameters, simulation parameters or stimulation
protocol, open spinemodel_fig6.m and investigate. Parameters are
clearly notated.
