Spatial restriction of GPCR signaling at nascent synapses by adhesion complexes drives excitatory synapse formation and specificity in the hippocampus.
Fly protein families Dprs and DIPs can create a multitude of complementary interfaces for homo- and heterophilic adhesion complexes, resulting in instructive roles for connectivity in the motor neuron circuitry.

Inhibition enhances the spatial specificity of high calcium influx for cooperatively stimulated synapses, suggesting that inhibitory inputs may regulate both synapse-specific and heterosynaptic plasticity to support learning and memory.
A genetic manipulation of the Nrxn1/3SS4+-Cbln1/2 complex reveals this signaling pathway has no role in synapse formation but functions to shape the NMDAR- and AMPAR-content at multiple types of synapses with distinct facets in diverse circuits.
Genetic and electrophysiological analyses reveal that the mechanisms orchestrating the induction and expression of homeostatic plasticity are compartmentalized and operate with exquisite specificity on both sides of the synapse.

Long-term live imaging in intact developing Drosophila brains reveals a role for N-Cadherin-mediated fast filopodial dynamics and growth cone stabilization during neural circuit assembly.
