mRNA copy number for glutamatergic and cholinergic neurotransmission differs among pyloric circuit neurons in the Jonah crab. A: mRNA copy numbers for choline acetyltransferase (ChAT). The anterior burster (AB), lateral pyloric (LP), and pyloric constrictor (PY) neurons show little expression, but the pyloric dilator (PD) neuron has higher ChAT copy numbers (P < 0.05). B: mRNA copy number for vesicular acetylcholine transporter (vAChT). As with ChAT, the PD neuron has the largest copy number for vAChT (P < 0.0001). C: mRNA copy number for glutamate vesicular transporter (vGluT). The LP and PY neurons have large numbers of vGluT mRNA, whereas the PD neuron expresses little vGluT mRNA compared with the other neuron types (P < 0.0001). D: mRNA copy number for acetylcholinesterase (AChE) is not significantly different among the 4 neuron types (P = 0.066). For all measurements: AB (a), n = 7; PD (b), n = 5; LP (c), n = 5; and PY (d), n = 6. Groups labeled a–d indicate a significant difference (P < 0.05) from one another through post hoc analysis. Error bars are SD.
