Figure 5:

Neuropeptidomic changes in the sinus glands and brain. Neuropeptide sequences with at least one significant (denoted by star) change are listed across the x-axis and grouped by family. PDH = pigment dispersing hormone, RPCH = red pigment concentrating hormone. The PDH highlighted in blue is identical in sequence in both the sinus glands and brain. The ratio for the intensity of reporter ions for a stress condition (1, 2, or 4 hr copper exposure) relative to the control are depicted on the y-axis as a log₂ ratio to clearly see up/downregulation of neuropeptides relative to the x-axis. The error bars denote the standard error of the mean (n=4).
