(B) The responses of a second preparation to SCPB. In this case four different concentrations of SCPB were used as well as a control saline trial. (C) The extent of the variability between preparations is illustrated by plotting the mean (±SD) burst frequency at each time point for 29 trials in 12 preparations during exposure to 2 x 10'6 A/ SCPB. (From Prior and Watson, 1987) neurons containing SCPB-like-immunoreactive-material (SLIM) that might be involved. Among the most prom- inent SLIM-reactive neurons were the right and left Bl buccal neurons (Prior and Watson, 1987). In addition to those neurons that clearly contain SCPB immunoreactive material, there are numerous cell bodies that are enmeshed by networks of immunoreactive fibers (, B7, FSB), which is suggestive of peptidergic endings near the target feeding neurons. The morphology of Bl was examined by intracellular injection of horseradish peroxidase (Fig. 5a). There are. Figure 5a.
