“…This cluster consists of ipsilaterally and bilaterally projecting neurons (OAAL2i and OA-AL2b, respectively). Importantly, they share striking structural similarity to the neurons PM4 and PM5 in the locust (Stern et al, 1995;Stern, 1999). They are shown to be involved in dishabituating the response of the descending contralateral movement detector.…”

“…Octopamine-like immunoreactivity in the locust brain has been described by Konings et al (1988), Stevenson and Spörhase-Eichmann (1993), Homberg (1994), and Stern et al (1995). There are at least 9 locations in the brain and optic lobes where octopamine-like immunoreactive cell bodies are found (Fig.…”

“…This figure is based: on (1) the observation that up to 181 cells are stained on one side, (2) the variability encountered in experiments aimed at labeling whole connectives (see Tables 1, 2), and (3) the limited resolution of such studies with respect to small neurons. So far, only a few cases of dye coupling of descending neurons with other brain cells have been reported (e.g., Goodman 1976;Stern et al 1995). This suggests that dye-coupled cells are rare and thus should only slightly distort the number of descending cells counted.…”

The number and distribution of descending brain neurons have been investigated in the cricket. The results are based on retrograde labeling of these cells with either Lucifer yellow or Neurobiotin via whole or small split portions of the cervical connectives. Various groups of cells and single neurons have been identified, and the morphology of more than 40 cells is described. Nearly 200 descending brain neurons can be stained via one cervical connective. Their perikarya are concentrated in clusters that occur ipsi- and contralateral to the filled connective and that lie dorsal and ventral in the brain. Descending cells only arborize in the nonglomerular neuropils of the brain and never branch in the optic lobe. Cells descending ipsilaterally never arborize in the contralateral hemisphere, whereas contralateral descending neurons often branch in both hemispheres. Irrespective of soma position, cells can arborize in the ventral and/or dorsal neuropils of the brain. Neurons with somata in the protocerebrum often have branches in the deutocerebrum and vice versa. The main arborizations of the cells from the prominent ventral i5 group are found in the same part of the protocerebrum. In contrast, various cells arborize in the ventral posterior deutocerebrum, but their somata are not located in different clusters. Thus, neurons from the same cluster may, but need not necessarily, arborize in the same brain area.
