Maturation of synaptic partners: functional phenotype and synaptic organization tuned in synchrony.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Maturation of principal neurons of the medial nucleus of the trapezoid body (MNTB) was assessed in the context of the developmental organization and activity of their presynaptic afferents, which grow rapidly to form calyces of Held and to establish mono-innervation between postnatal days (P)2 and 4. MNTB neurons and their inputs were studied from embryonic day (E)17, when the nucleus was first discernable, until P14 after the onset of hearing. Using a novel slice preparation containing portions of the cochlea, cochlear nucleus and MNTB, we determined that synaptic inputs form onto MNTB neurons at E17 and stimulation of the cochlear nucleus can evoke action potentials (APs) and Ca(2+) signals. We analysed converging inputs onto individual MNTB neurons and found that competition among inputs was resolved quickly, as a single large input, typically larger than 4 nA, emerged from P3-P4. During calyx growth but before hearing onset, MNTB cells acquired their mature, phasic firing property and quantitative real-time PCR confirmed a coincident increase in low threshold K(+) channel mRNA. These events occurred in concert with an increase in somatic surface area and a 7-fold increase in the current threshold (30 to >200 pA) required to evoke action potentials, as input resistance (R(in)) settled from embryonic values greater than 1 GΩ to approximately 200 MΩ. We postulate that the postsynaptic transition from hyperexcitability to decreased excitability during calyx growth could provide a mechanism to establish the mature 1:1 innervation by selecting the winning calyceal input based on synaptic strength. By comparing biophysical maturation of the postsynaptic cell to alterations in presynaptic organization, we propose that maturation of synaptic partners is coordinated by synaptic activity in a process that is likely to generalize to other neural systems.
