What do neurons add to an organism?
"The extraordinary ability to survive the removal and replacement of its entire nervous system makes Hydra uniquely suited to address the question of what neurons add to an extant organism"

Effect of monochromatic light on the behavior of the ctenophore Mnemiopsis leidyi.
4 maneuvering patterns identified:
1 - turn and shift
2 - move sideways
3 - move up along the beam followed by a turn
4 - drop down, stop, lift up and turn

Bacteria captured on the collar of #choanoflagellates slow swimming speed. Wonderful work by Mimi Koehl and colleagues.
Thrilled to see our latest work highlighted on the cover of Science 🤩. Our discoveries challenge our understanding of nervous systems and their evolution. Link to the paper here:
Very excited to represent ctenophores (comb jellies) at the Neuro-Evo conference "A Comparative Approach to Cracking Circuit Function III" @HHMIJanelia in May 2023.

Wonderful article about Michael Sars, his son and their famous discoveries, for the very first time, the describtion of the different stages of a jellyfish life cycle. And ctenophores included as well 🤩.
