Neuron Layouts


Layouts refer in the most simple sense to how any group of neurons is positionally organized in a Simbrain network window. Currently three layout types are possible (plus an additional type not accessable in the GUI), and can be applied to any selected set of neurons or specified before the creation of a subnetwork.

Specifically, subnetworks are initialized with a pre-defined number of neurons laid out in an appropriate manner. There are typically several options, or layout styles, which are described here. To choose a layout style, click on the Layout tab of the initialization dialog that appears when you create a new subnetwork. (Shown below and to the right).

Note: In each case below, "initial position" corresponnds to the last position clicked on screen, or the upper left corner if no position has been clicked (this is the same as with neurons). Examples of each kind of layout can be found below the pictures below.


Neuron Layout Demo  Subnetwork Layout



Grid

Neurons are laid out in a grid, beginning at an initial position and moving downward.

Horizontal Spacing between neurons: Distance between the neurons from left to right.

Vertical Spacing between neurons: Distance between the neurons up and down.

Manully set number of columns: If checked, the default behavior is overrideen and you can choose how many columns the grid has, using the number of columns field.  Default behavior is a square grid.

Number of columns: How many columns there will be in the grid (if manully set number of columns is selected).

Line

Neurons are laid out in a line, beginning at an initial position.

Layout Style: Whether the neurons are laid out horizontally or vertically.

Spacing between neurons: Distance between the neurons.


Hexagonal

Neurons are laid out in a hexagonal pattern.

Horizontal Spacing between neurons: Distance between the neurons from left to right.

Vertical Spacing between neurons: Distance between the neurons up and down.

Manully set number of columns: If checked, the default behavior is overrideen and you can choose how many columns the grid has, using the number of columns field.  Default behavior is a square grid.

Number of columns: How many columns there will be in the grid (if manully set number of columns is selected).
