[Single interneuron coordinates wing and tail movements in pteropod mollusk].

Nervous centers that coordinate rhythmical movements with body stabilization in space are well known in vertebrates. Here we report a single identified interneuron CPB3c (cerebropedal neuron c from group B3) that serves the same function ofpostural control during locomotion in a simple animal model--the marine pteropod mollusk Clione limacina. CPB3c interneuron integrates inputs from statocysts and locomotor generator and translates signals to tail motorneurons. So, this neuron has perfect connections to fulfill the coordinative function.
