Whole-body connectome of a segmented annelid larva

The paper describes the whole-body synaptic connectome of a segmented annelid larva, identifying segment-specific and repeated cell types and pathways.

Nitric oxide feedback to ciliary photoreceptor cells gates a UV avoidance circuit

The paper identifies a NO-mediated retrograde signaling pathway in ciliary photoreceptor cells that gates a UV avoidance circuit in Platynereis dumerilii larvae.

Whole-animal connectome and cell-type complement of the three-segmented Platynereis dumerilii larva

A whole-body serial electron microscopy volume of a three-segment Platynereis dumerilii larva gives over 1,500 reconstructed neurons, 6,500 non-neuronal cells, 180 neuronal types and traced sensory-to-effector pathways.

Neural circuitry of a polycystin-mediated hydrodynamic startle response for predator avoidance

The paper identifies polycystin-mediated mechanosensation in Platynereis larvae that triggers a coordinated startle response for predator avoidance.

Ciliary and rhabdomeric photoreceptor-cell circuits form a spectral depth gauge in marine zooplankton

The paper shows ciliary and rhabdomeric photoreceptors in Platynereis larvae functionally integrate to determine vertical swimming direction based on light ratios, acting as a depth gauge.
