The contribution of intracellular calcium stores to mEPSCs recorded in layer II neurones of rat barrel cortex.
Article in The Journal of physiology, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 54 papers.
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
Loading slices of rat barrel cortex with 50 microM BAPTA-AM while recording from pyramidal cells in layer II induces a marked reduction in both the frequency and amplitudes of mEPSCs. These changes are due to a presynaptic action. Blocking the refilling of Ca(2+) stores with 20 microM cyclopiazonic acid (CPA), a SERCA pump inhibitor, in conjunction with neuronal depolarisation to activate Ca(2+) stores, results in a similar reduction of mEPSCs to that observed with BAPTA-AM, indicating that the source for intracellular Ca(2+) is the endoplasmic reticulum. Block or activation of ryanodine receptors by 20 microM ryanodine or 10 mM caffeine, respectively, shows that a significant proportion of mEPSCs are caused by Ca(2+) release from ryanodine stores. Blocking IP(3) receptors with 14 microM 2-aminoethoxydiphenylborane (2APB) also reduces the frequency and amplitude of mEPSCs, indicating the involvement of IP(3) stores in the generation of mEPSCs. Activation of group I metabotropic receptors with 20 microM (RS)-3,5-dihydroxyphenylglycine (DHPG) results in a significant increase in the frequency of mEPSCs, further supporting the role of IP(3) receptors and indicating a role of group I metabotropic receptors in causing transmitter release. Statistical evidence is presented for Ca(2+)-induced Ca(2+) release (CICR) from ryanodine stores after the spontaneous opening of IP(3) stores.
