Nevertheless, stomatopods have visual systems unparalleled in complexity and a sixth
abdominal ganglion that is larger than the other five abdominal ganglia (shown in the scale drawing of the CNS in Fig.

abdominal ganglion (6 A.G.) and associated ablation and microelectrode studies.
The morphology of the fourth
abdominal ganglion of the hermit crab: a light microscope study.
The
abdominal ganglion together with the attached siphon nerve and the pleuroabdominal connectives were dissected out in a cooled "zero-calcium" solution (NaCl, 338 mM; KCI, 10 mM; Mg[Cl.sub.2], 150 mM; 4 [degrees]C).
We found that LTH of gill withdrawal depends on both protein synthesis and gene expression, because it is blocked by infusion into the
abdominal ganglion of either anisomycin (Ezzeddine and Glanzman, 2003) or actinomycin-D (Ezzeddine et al., 2004).
The CPR in crayfish is composed of two bilaterally symmetrical neurons located in the 6th
abdominal ganglion. Like those in Limulus, they exhibit spontaneous action potentials in the dark and a tonic increase in the frequency of action potentials in light (Prosser, 1934; Kennedy, 1963); but their peak spectral response is at 500 nm (Bruno and Kennedy, 1962; Larimer, 1966) rather than at 425 nm or lower.

abdominal ganglion. Nervous systems are made up of large numbers of neurons, and many of these are active during the generation of behaviors.
