Ectopic head regeneration after nervous system ablation in a sea anemone
Via genetic ablation of neurons, Mazloumi Gavgani et al. show that the nervous system is essential for defining axial polarity during whole-body regeneration in the sea anemone Nematostella vectensis.

Ctenophores possess a unique aboral organ that acts as a multisensory center, controlling complex behaviors. We’ve now created a ctenophore model integrated with our 3D volume EM data. Puts it into perspective. Check out our recent work here:
