Fig. 2. Anti-GABA immunocytochemistry of peripheral nerves and muscles. (A) Three
GABA-immunoreactive axons (arrowheads) enter nerve 6 (N6) as it branches off
the posterior pro-mesothoracic connective. (B) Branching point of mesothoracic
nerve 1 (N1) as it divides into N1B (here still including N1C: N1B/C) and N1D
(compare Figs 1 and
6). A sensory branch that
supplies the sternum (see ventralmost label in
Fig. 1) also buds off at this
point. Two immunoreactive axons run from the prothoracic ganglion through N1
and into N1B to supply M59. Only the larger-diameter axon gives off a branch
into N1D to supply M81 and M82. (C) GABA-immunoreactive axonal branches and
terminal boutons on M59. Two immunoreactive axons supply the muscle
(arrowheads). Scale bars, 35 µm (A,B); 100 µm (C).
