• base: 100
• Represents the total number of AMPAR particles to simulate.

By default, these particles will behave like GluR2, in that, the entire PSD and periPSD region will have one unified diffusion rate scalar. If 'Use GluR1 receptors' is selected as a Run Item, this total number will allocate exactly half of the particles to the GluR1 pool and half to the GluR2 pool. So at the base value of 100, with 'Use GluR1 receptors' checked, there will be 50 particles representing GluR1 and 50 representing GluR2.

• base: 1000
• Total number of iterations to run the main loop function of the simulation.

This value represents the number of 'steps' or 'seconds' being simulated. Each iteration of the main loop performs many functions, but its most basic function is to generate random, but diffusion rate-dependent, step sizes for each particle; and then update each particle's location accordingly.

A note on processing speed: If either of the Run Items 'View Live 2D Plot' or 'View Live 2D Plot' are selected (ON), to simulate 1000 steps, it takes roughly 100 seconds on my macbook pro laptop¹ and about 10 seconds on my custom built desktop². The big difference between the two is due to graphics rendering (the custom desktop has better specs in all categories, but an especially better graphics card). Keep your hardware in mind when choosing these step values.

When the Run Items 'View Live 2D Plot' or 'View Live 2D Plot' are not selected (OFF), it takes about 20 seconds to run 5000 steps on my macbook pro laptop.

Long story short, the live graphics 2D and 3D plot will make the simulation run much slower. If you are only interested in seeing the final output graphs, turn the 2D and 3D plots OFF and save yourself the time.

• base: 0.3
• diffusion rate coefficient for the extrasynaptic (ES) non-PSD regions of the simulation.

This value is used to generate the baseline diffusion rate for all particles in the model. This rate will be used when the particles are in ES space regardless of which Run Items are selected. All other diffusion rates are scaled from this baseline value.

• base: 0.03
• diffusion rate coefficients for the PSD and periPSD zones.
• Run Item Dependents
  • PSD-96 Clusters (OFF)
  • Homeostatic Regulation (OFF)
  • Manually set step size (OFF)

These diffusion rate coefficients will be used only when the Run Items 'Homeostatic regulation' and 'PSD-95 Clusters' are not selected (OFF).

If you want to use these values, DO NOT select the Run Item - 'Manually set step size' unless you want all particles to take the same exact step size for every step throughout the entire simulation (i.e. step sizes will not be random). A fixed-manual step size is not necessary to generate diffusion rates at the value entered into these fields.

• base: 60 and 30
• specifies a high and low tolerance range for total particles in PSDs
  • inside this range, Clusters will run at baseline values
  • outside of this range, Clusters will temporarily adjust several parameters leading to growth or shrinking.
• Run Item Dependents:
  • PSD-95 Clusters
  • Homeostatic Regulation
