Axonal arborisation growth is regulated by dynamic, focal localisations of Neurexin and Neuroligin that provide stability for filopodia, enabling a 'stick and grow'-based mechanism, wholly independent of synapse formation.
A continuously expressed LIM HD factor, Lmx1b, acts at successive stages to orchestrate the progressive morphological maturation of a long-range profusely arborized neuromodulatory axonal projection pathway.
The combination of single-cell transcriptomics and whole-brain mapping of bulk and single-cell projections reveals the relationship between the molecular architecture, cell body distribution, and axonal arborization of serotonin neurons.
A single subpopulation of photoreceptors constitutes a shared node in the neural networks that regulate light-dependent maturation of the circadian clock and light-independent refinement of retinal ganglion cell projections to the brain.
The organization of layered/laminated axon projections in specific regions of the fruitfly central brain is regulated by short-range repulsive guidance and is critical for local inhibitory circuit formation and function.
The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.
