The cnidarian homolog of the nervous system is a nerve net that is largely ectodermal.
These rhopalial ganglia presumably sort this information and then distribute it to the appropriate effectors, the swim musculature, via the distributed nerve net of the subumbrella.
The nerve nets for these areas would be good antennae.
The nerve net has been implicated in the behavioral coordination amongst polyps in the colony.
