Fantastic, thank you it worked perfectly!

EDIT: If I wanted to have my caption read like this:

Figure 2: Sleep spindle (left) and K-complex (right) waveforms in typical stage N2 sleep as seen on an EEG. Each vertical black line denotes 1-second of recording.

But have the TOF read like:
Figure 2: Sleep spindle and K-complex waveforms in typical stage N2 sleep as seen on an EEG.

how would I do this? I tried doing multiple style separators within the caption but it didn't work...
