Inter-Stimulus-Interval Dependence in Auditory Cortex Reflects Perceptual Organization of Streams Under Informational Masking.
Article in Psychophysiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The perceptual saliency of a regular sound sequence embedded into a well-chosen multi-tone-masker background fluctuates despite the absence of change in the physical stimulus. When such tone streams are perceived, each tone of the stream evokes a negative-going response referred to as awareness-related negativity (ARN). Here we probe if the ARN amplitude shows a dependence on the inter-stimulus interval (ISI) within perceived tone streams, similar to the N1 response evoked by unmasked tone streams independently of a task. Isochronous target streams were presented under multi-tone masking with ISIs of 500, 850, and 1200 ms, while listeners indicated when they perceived the onset of the target streams. A control experiment applied the same tone streams without masking in the presence of a second, narrow-band noise stream. In two separate runs, listeners either attended the tone streams and indicated their beginning and ending, or they attended the distractor streams, in which they performed a deviance detection task. Activity in auditory cortex was recorded with magnetoencephalography. Experiment 1 revealed a significant amplitude increment of the ARN with increasing ISI. In Experiment 2, the known amplitude dependence of the N1 was observed for attended and unattended runs alike. Critically, the negative difference waveform (Nd) between attended and unattended runs did not increase with the ISI. These results support an interpretation of the ARN as being related to the neural formation of an auditory stream and not as a pure reflection of attentional response enhancement.
