This study identifies glutamatergic elements in the neural system of the pelagic tunicate Doliolum sp., suggesting glutamatergic systems originated in the common ancestor of tunicates and vertebrates.

This study compares the neural and muscle systems in the subumbrella of 14 hydrozoan jellyfish species, finding a strong correlation between subumbrella neural networks and smooth radial muscles.

This study identifies glutamate-immunoreactive cells in eight hydrozoan species, revealing diverse glutamatergic systems and suggesting independent recruitment of glutamate and GABA as neurotransmitters.

This study identifies glutamate-immunoreactive neurons and muscle fibers in ctenophores, revealing species-specific glutamate expression patterns linked to neural function and energy demands.

The paper maps the neural architecture of the siphonophore colony using immunohistochemical markers to reveal neuroanatomical interactions and subpopulations across different zooid classes.

The paper describes the structure and function of the nervous system in Nanomia septata, showing how it coordinates swimming bells for foraging and escape behaviors through a combination of giant axons, nerve networks, and FMRFamide-immunoreactive tracts.

The paper examines the distribution and evolutionary dynamics of dopaminergic neurons in molluscs, finding moderate conservation in central ganglia and diversification in peripheral sensory-like neurons.

The paper explores using ctenophores as models to build neurobots and chimeric animals, demonstrating their ability to survive autonomously.

The paper creates a comprehensive atlas of the Drosophila larval nervous system using single-cell transcriptomics and validates findings with RNA-FISH, revealing gene expression changes linked to behavioral states.

The paper describes the structure and function of the nervous system in the nectophores of Nanomia bijuga, highlighting roles in locomotion, sensory input, and chemical release.
