A neuron that regulates locomotion makes a potential sensory cilium lying over the C. elegans egg-laying apparatus

The paper identifies previously-undescribed branches of PVP neurons in C. elegans that may function as sensory cilia, but functional validation remains speculative due to technical limitations.

Subthreshold serotonin signals combined by the G proteins Gαq and Gαs activate the C. elegans egg-laying muscles

The paper shows that subthreshold serotonin signals via Gq and Gs pathways combine in C. elegans egg-laying muscles to promote egg laying, while individual signals alone are insufficient.

Cellular expression and functional roles of all 26 neurotransmitter GPCRs in the C. elegans egg-laying circuit

The paper maps GPCR expression and function in C. elegans egg-laying circuit, revealing redundancy and compensation in receptor signaling.

Serotonin and neuropeptides are both released by the HSN command neuron to initiate C. elegans egg laying

The paper shows that HSN neurons in C. elegans release both serotonin and NLP-3 to coordinate egg-laying muscle activity, with the two signals acting redundantly.

Activity of the C. elegans egg-laying behavior circuit is controlledby competing activation and feedback inhibition

The paper investigates the neural circuit controlling C. elegans egg-laying behavior, identifying signals that switch between active and inactive states.
