Brief Communication Inhibitory Control at a Synaptic Relay
The mammalian medial nucleus of the trapezoid body (MNTB) harbors one of the most powerful terminals in the CNS, the calyx of Held. The mechanisms known to regulate this synaptic relay are relatively ineffective. Here, we report the presence of a remarkably robust and fast-acting glycinergic inhibitory system capable of suppressing calyceal transmission. Evoked glycinergic IPSCs were relatively...
متن کاملAre inhibitory synaptic conductances on thalamic relay neurons inhomogeneous? Are synapses from individual a!erents clustered?
Standard and dynamic current clamps were used to emulate dendritic GABA-Aergic postsynaptic currents (IPSCs) in a reconstructed thalamic relay neuron. The variability of somatically recorded single events was an order of magnitude smaller than reported in experimental work, suggesting that experimentally observed variability of miniature IPSCs re#ects variable synaptic strength rather than "lte...

متن کاملSNR Maximization at CSI Aware AF Relay
This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...
متن کاملInhibitory control of synaptic and behavioral plasticity by octopaminergic signaling.
Adrenergic receptors and their ligands are important regulators of synaptic plasticity and metaplasticity, but the exact mechanisms underlying their action are still poorly understood. Octopamine, the invertebrate homolog of mammalian adrenaline or noradrenaline, plays important roles in modulating behavior and synaptic functions. We previously uncovered an octopaminergic positive-feedback mech...
