Local facilitation of plateau potentials in dendrites of turtle motoneurones by synaptic activation of metabotropic receptors.
Article in The Journal of physiology, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
1. The spatial distribution of synaptic facilitation of plateau potentials in dendrites of motoneurones was investigated in transverse sections of the spinal cord of the turtle using differential polarization by applied electric fields. 2. The excitability of motoneurones in response to depolarizing current pulses was increased following brief activation of either the dorsolateral funiculus (DLF) or the medial funiculus (MF) even when synaptic potentials were eliminated by antagonists of ionotropic receptors. 3. The medial and lateral compartments of motoneurones were differentially polarized by the electric field generated by passing current between two electrodes on either side of the preparation. In one direction of the field lateral dendrites were depolarized while the cell body and medial dendrites were hyperpolarized (S- configuration). With current in the opposite direction the cell body and medial dendrites were depolarized while lateral dendrites were hyperpolarized (S + configuration). 4. Following brief activation of the DLF the excitability and the generation of plateau potentials were facilitated during differential depolarization of the lateral dendrites but not during differential depolarization of the cell body and medial dendrites. Following brief activation of the MF the excitability and generation of plateau potentials were facilitated during differential depolarization of the cell body and medial dendrites but not during differential depolarization of the lateral dendrites. 5. It is concluded that the synaptic facilitation of the dihydropyridine-sensitive response to depolarization is compartmentalized in turtle motoneurones.
