a Location of recording sites within the PBN for the Sham (blue dots), Partial DA lesion (orange dots) and Total DA lesion (red dot) groups. b Left: Individual recordings illustrating irregular and bursting firing patterns. Right: The proportion of irregular (blue), bursting (yellow), regular (dark grey) and mixed (light grey) patterns recorded in the Sham, Partial and Total DA lesion rats. c Histograms of the means (±SEM) of firing rate (left), firing rate during the control (cont) or stimulation (stim) period (middle) and nociceptive response magnitude (right) measured in the Sham (blue), Partial (orange) and Total (red) DA lesion groups.
