Neurons are mapped for developmental features (lineage, hemilineage, temporal identity) and connectomic features (morphology, synapse localization and connectivity) to reveal correlations that can be tested experimentally.

A new approach for fast, sparse neural circuit mapping allows circuit structure, physiology, and behavior to be quantified in the same animal and across many animals.

R7 photoreceptors require the endosomal protein Lost and Found to form stable connections only when this protein is also present in neurons that are synaptic partners of R7.
Teneurin-2, a synaptic organizer, localizes to microtubule-rich inhibitory synapses and recruits microtubules via interaction with end-binding proteins, and this mechanism enables GABAA receptors exocytosis.
The work uncovers a muscle-epidermis-glia signaling axis, modulated by protease mig-17 and the basement membrane, that regulates synaptic allometry during growth in Caenorhabditis elegans.
