Worm Circuitry Explorer

The Worm Circuitry Explorer is a tool that allows visual and interactive exploration of the connectome of Caenorhabditis elegans (C. elegans). Its main purpose is to give researchers interested in modelling a specific worm behaviour the tool to extract subcircuits that may underlie the behaviour in question. For background information about this app see the About section.

Usage

Hover
Highlights first-degree neighbourhood of hovered neuron.
Click
Locks in highlighting and shows neuron metadata in panel on the right. The selected neuron will be indicated by a dashed outline.
Drag
Manually moves and pins a neuron to a specific position. Pinned neurons are indicated with a solid black outline.
Dbl-click
Releases a pinned neuron.
In addition, dragging or swiping the background moves and zooms the network view respectively.

UI controls

The panels on the left control which part of the full network is currently available in the browser (Subgraph panel), and which elements of the network are currently visible (Visibility panel). It also allows you to find a single neuron by name.

Extracting a subcircuit

First choose two or more neuron groups in the Subgraph panel. Select whether you care about the direction of connectivity (e.g. from sensory to motor neurons), or whether you require all bidirectional paths. Then choose filter settings to constrain the subcircuits maximal path lengths (longer is more costly) and minimum number of synapses per connection. Now Fetch the results. In order to then add back in all existing connections between the returned neurons (irrespective of filter settings), click Expand.

Information panels

The UI panels on the right display information about the currently visible network as well as individual nodes. It also offers a means to export the current network in various formats.
