Research Whole-body connectome of a segmented annelid larva
A digital atlas of every cell in a developing marine worm reveals how networks across the body coordinate sensing and movement, and provides insights into the evolution of the nervous system
This important study is an advancement towards the understanding of animal nervous system organization and evolution by providing an exceptional, high-quality and detailed description of the entire connectome of the 3-day larva of the marine annelid Platynereis dumerilii. It provides a wealth of data on cell type diversity and the modules that interconnect them. Its strength is the massive amount of high-quality data, although this is also partly a weakness as it can make the work difficult to read and digest scientifically. This work lays the foundations for studies on cell type diversity, segmental vs. intersegmental connectivity, and mushroom bodies, but will certainly also be of use to scientists interested in other nervous systems parts, their functions, and evolution.
