Spinal Shox2 interneurons are strongly interconnected by gap junctional coupling in a function-specific manner, which provides a mechanism for synchronization of rhythm-generating neurons and may contribute to locomotor rhythmicity.
An unexpected species difference in electrical coupling of analogous neuroendocrine dopamine neurons in rats and mice reveals a role for gap junction connectivity as a band-pass filter for oscillation frequency in neural networks.
Developing long bones contain distinct mesenchymal stem-cell populations derived from mesoderm and neural crest, which have specialized functions in skeleton formation and the establishment of the hematopoietic stem-cell niche, respectively.
The 'missing' class of Caenorhabditis elegans excitatory motor neurons, AS, contribute to propagation and coordination of body waves, integrating information from, and feeding back to premotor interneurons byelectrical signaling.
Sensory neurons that monitor ambient oxygen control a cascade of responses across multiple layers of interneurons to switch the global state of the nematode C. elegans, reprogramming behavior and gene expression to enable escape from or adaptation to surface exposure.
Optogenetic activation reveals a larger role for the fly brain 'sleep switch' neurons in controlling both waking and sleeping behavioral responsiveness, partly via a parallel channel involving innexin6 electrical synapses.
