The models from the text were implemented into the Virtual Cell by Johann Frederick Cutiongco.

The following BioModels are available from user: 'CompCell'
Chay-Keizer ER - Models pancreatic beta-cell bursting. Described in 5.4 and illustrated in Figure 5.21.
Hodgkin-Huxley - Models electrical behavior of the squid giant axon. Used to demonstrate interacting ion channels. Described in 2.5.
Keizer-Levine Open-Cell - Models calcium oscillations in bullfrog sympathetic ganglion neurons via RyR channel kinetics. Described in 5.2.3 and illustrated in Figure 5.8.
L-Type Calcium Channels - Models L-type calcium channel kinetics in the Aplysia neuron. Used to demonstrate the rapid equilibrium approximation. Described in 4.1 and illustrated in Figure 4.3.
Morris-Lecar Coincidence Detection - Demonstrates coincidence detection for excitatory inputs. Described in 6.4 and illustrated in Figure 6.9.
Morris-Lecar Gap Junction Coupled - Demonstrates electrical coupling and gap junctions. Described in 6.1.
Morris-Lecar Mutual Excitation - Demonstrates how fast excitatory synapses lead to synchrony and slow excitatory synapses lead to asynchrony in two identically electrically coupled cells. The only parameter modified is beta (=1000/s in Figure 6.6A and =100/s in Figure 6.6C). Described in 6.3.
Morris-Lecar Mutual Inhibition - Demonstrates how fast inhibition leads to antiphase behavior (for t<0.8, beta=1000/s) and slow inhibition leads to in-phase behavior (for t>0.8s, beta=100/s). SurfToVol_PlasmaMembrane 1 and SurfToVol_PlasmaMembrane 2 were changed to 1806 to cancel out KMOLE in the equations for s1 and s2 kinetics. Described in 6.3 and illustrated in Figure 6.7.
Morris-Lecar Mutual Type II - Models electrical behavior of barnacle muscle fiber. Used to demonstrate interacting ion channels. Described in 2.4.

How to Access the Published Models

The Virtual Cell is being referenced in published articles since it was used to create the experimental models discussed in these articles. The models have been made public so that other Virtual Cell users may access them and view the results. To access a public model proceed as follows:

BioModels

  1. log on to the Virtual Cell software.
  2. In the Database pane (lower left), Select the BioModels tab from within the VCell Database.
  3. Published models are within the Public Biomodels folder; models are organized by "user name: model name". Open the Search box to search by user name or model name.
  4. Double click the model to open.
  5. If you wish to modify the model or run new simulations, copy it into your VC Workspace under your own User account.
