  • In vertebrates, the excitatory synaptic drive for inducing spinal central pattern generators (CPGs) — which are responsible for generating rhythmic movements — can originate from either supraspinal glutamatergic inputs or from within the spinal cord. A spinal input to the CPG is now identified using a combination of intersectional gene expression and optogenetics in zebrafish larvae; the results reveal that during early development Kolmer–Agduhr cells provide a positive drive to the spinal CPG for spontaneous locomotion.

  • In an inter-laboratory study, the authors compare the accuracy and performance of three optical density calibration protocols (colloidal silica, serial dilution of silica microspheres, and colony-forming unit (CFU) assay). They demonstrate that serial dilution of silica microspheres is the best of these tested protocols, allowing precise and robust calibration that is easily assessed for quality control and can also evaluate the effective linear range of an instrument.
