By combining #connectomics and high-speed imaging, we could infer a function for the nerve net in the coordination of the beating-arrest cycles and beat frequency of balancer cilia.

The four bundles of balancer #cilia showed coordinated beating and arrests, then re-beats, but the level of coordination was different between the two planes.

The four bundles of balancer #cilia showed coordinated beating and arrests, then re-beats, but the level of coordination was different between the two planes.
Kei then used a horizontal microscope and high-speed imaging to characterise the beating of balancer #cilia viewed from two orientations (along the tentacular and sagittal planes).

The organisation of the nerve net was intriguing, forming a large net innervating all four quadrants Q1-Q4 and two smaller nets, one each for Q1-Q2 and Q3-Q4.

We found a unique nerve that contrary to our expectations did not receive synapses from the balancers (input-output model) but formed synapses on the balancers (coordination model).

The balancer is part of the aboral organ and is divided into four quadrants (Q1-Q4) with two axes of symmetry, a tentacular (T) and a sagittal (S) plane.

Ctenophores or comb jellies are marine pelagic animals that can sense their orientation and reorient relative to the gravity vector using a unique gravisensory organ, the balancer.
