Specific Brain Regions Involved in Decoding of the Anger Acoustic Parameters.
Article in Basic and clinical neuroscience. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: The present study aimed to identify brain regions sensitive to emotion-specific acoustic parameters in healthy individuals. Methods: Three pseudo-words in the form of one stimulus were consecutively spoken with neutral and angry prosody. Then, we changed the acoustic parameters (mean fundamental frequency [F0], intensity, and speech tempo) in angry prosody. The stimuli were presented in a functional magnetic resonance imaging experiment to detect anger or neutrality. Results: Stronger activation in the left superior temporal gyrus (STG) and Heschl's gyrus (HG) was observed when the mean F0 converted from 300 Hz to 250 Hz. Increased activity in the right posterior STG and posterior middle temporal gyrus (MTG) was revealed in more intensity anger prosody. Moreover, we found stronger activity in the right mid-STG, MTG, and the left STG in a faster speech tempo. Conclusion: According to the increased activity in the STG and MTG of both hemispheres following the more intense anger (lower fundamental frequency, more intensity, and faster speech tempo), a more intense comprehension of anger may result from the sending different information from these regions to the inferior frontal gyrus (IFG) and orbital frontal cortex (OFC).
