GABA-like immunoreactivity in a common inhibitory neuron of the antennal motor system of crickets

In crickets, a deutocerebral motoneuron sends axon collaterals to 6 of the 7 antennal muscles. Previous results indicated that this neuron exerts inhibition on these muscles and thus may be a common inhibitory motoneuron. In our present study, we show by doublelabelling, i.e. retrograde cobalt-filling and GABA-immunocytochemistry, that this neuron is GABA-immunoreactive, thus demonstrating that one common inhibitory motoneuron is part of the antennal motor system of crickets.
