The network is depicted in Figure 4, where solid lines with an arrow head denote activation and dash pointed lines with a hammer head denote inhibition.
The button has 4 small lines with an arrow pointing both up and down.
A blue line with a pink arrow is used to denote merged undirected and directed edges.
In the integrated network, an undirected edge is drawn as a blue line while a directed edge is drawn as a pink line with a pink arrow to indicate the direction of the interaction (e.g. transcriptional regulation).
There's a dot for New York and a dot for Chicago, and if New York is at Chicago, I'll draw a line between them with an arrow from New York to Chicago".

After simultaneous Ca2+ imaging of bilateral LHs, the ipsilateral plF and contralateral mACT was transected (red zigzag line) with an infrared laser (dashed red arrow).
The black line with double arrow is the band gap energy of pure TiO2 corrected by scissors operator.
If we expand the first layer, we can see that the first two interactions are direct stimulatory (normal arrow), the third one is indirect and inhibitory (dashed line with blunted arrow).
