  • The authors describe the mechanism of exo-endocytosis coupling at synapses. They find that actin forms a ring around the region of exocytosis. This ring conserves membrane area, allowing induction of inward membrane buckling following exocytosis.

  • Time-resolved electron microscopy reveals that intersectin-1 and endophilin A1 condensates hold replacement synaptic vesicles close to release sites. Without this, replacement vesicles are unavailable for immediate use, causing synaptic depression in response to stimulation trains.

  • Axons have always been assumed to be cylindrical. Using in silico modeling and cryopreservation of tissues, Griswold et al. demonstrate that unmyelinated axons of the mammalian central nervous system exhibit pearls-on-a-string morphology through their entire length.

  • Action potentials induce synchronous and asynchronous release of neurotransmitters. Here, the authors show that the synchronous and asynchronous release sites are aligned with AMPARs and NMDARs, respectively, in mouse hippocampal synapses. This organization allows efficient activation of NMDARs.

  • Kusick et al. capture snapshots of synaptic vesicle docking and fusion using a new time-resolved electron microscopy technique. They find that vesicles are replaced milliseconds after they fuse, which may contribute to short-term synaptic plasticity.
