Functional specialization of male and female vocal motoneurons.
Article in The Journal of neuroscience : the official journal of the Society for Neuroscience, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
Vocal behaviors of African clawed frogs (Xenopus laevis) are produced by a single pair of muscles. This simplification, relative to other vertebrates, allows us to more easily determine how CNS motor pathways function to produce sex-specific songs. We describe here certain sexually differentiated properties of vocal motoneurons that are matched to male and female vocal demands. Both active and passive membrane properties differ between the sexes. Male motoneurons have lower input resistances and larger membrane capacitances than female motoneurons. Two distinct firing patterns are found, in different proportions, in males and females. The strongly adapting neurons that predominate in males initiate spikes at short, reliable latencies, whereas the weakly adapting motoneurons characteristic of females translate graded levels of depolarization into different firing rates. Low-threshold potassium currents (IKL) predominate in males. Hyperpolarization-activated cationic currents (IH) are found almost exclusively in males. Modeling results indicate that sex-typical active and passive properties can account for the occurrence of strongly and weakly adapting spike trains in the sexes. In particular, IKL seem to play an important role in determining the firing patterns of neurons. We suggest that these physiological differences facilitate transformation of synaptic inputs into male- and female-specific outputs that generate sexually distinct songs in vivo.
