SI, specific inhibitors; CI, common inhibitors. a and b designate the segmental homologues (homonoms) of CIa and CIb identified in the present study; SI neurons are specified by subscripts according to the muscle they innervate.
Homonomy of SI87 in T2 and CIa in abdominal ganglia is predicted on morphological grounds.
Innervation data for T1 (prothoracic ganglion), P. Bräunig, personal communication (see also Bräunig,1993; Bräunig et al.,2002).
Innervation data for T2 (mesothoracic ganglion) through A3 (last abdominal neuromere fused to T3) are predictions based on the present study, verified only in selected cases (data not shown; T. Müller, personal communication).
Muscles marked by question marks and bold print are predictions based on homonomy.
