The alpha-synuclein fibril structure reported here buries residues 50-57 at the interface between its two protofilaments, suggesting that familial Parkinson's disease associated mutations in these residues lead to a structure not compatible with the one presented here.
Active zone release probability is correlated with calcium channel density and calcium influx at single release sites, with release strength increasing in an activity-dependent manner during synapse maturation.
Neuroligin 1 is a critical adhesion molecule which organizes AMPA receptor nanodomains in close vicinity to pre-synaptic release sites, and whose genetic or chemical disruption severely impairs synaptic transmission properties.
Plexin controls the spatial distribution of synapses by locally inhibiting Rap2 small GTPase activity along the axon, and a Rap2 effector, TNIK, which also plays a key role in inhibiting synapse number.
Membrane potential recordings in awake mice from two genetically defined classes of neocortical inhibitory neurons reveal their distinct patterns of activity and unitary excitatory synaptic inputs, which are differentially modulated by behavior and local network activity.
Investigation of synapse development using a single neuron system illuminates how individual neurons specify connectivity with their postsynaptic partners and the central role of the synaptic organizer neurexin in this process.
