For 10 points, name these structures that form between namesake pre- and post-neuronal processes and pass neurotransmitters through their namesake clefts.
RIBEYE labeling visualizes the ribbon type of these structures. These structures are formed by a "handshake" between NLGN and the LNS domain of NRXN. Gephyrin (JEFF-rin) and PSD-95 provide scaffolding for two varieties of these structures. Molecules used in them are maintained in a readily-releasable pool by certain SNAREs. Their tripartite model includes astrocytes. Some cells induce IPSPs through the axo-dendritic type of these structures by releasing namesake vesicles carrying GABA. Pruning and long-term potentiation modulate their "plasticity."
