Caudate serotonin signaling during social exchange distinguishes essential tremor and Parkinson's disease patients.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Dynamic changes in dopamine, noradrenaline, and serotonin release are believed to causally contribute to the neural computations that support reward-based decision making. Accordingly, changes in signaling by these systems are hypothesized to underwrite multiple cognitive and behavioral symptoms observed in many neurological disorders. Here, we characterize the release of these neurotransmitters measured concurrently in the caudate of patients with Parkinson's disease or essential tremor undergoing deep brain stimulation surgery as they played a social exchange game. We show that violations in the expected value of monetary offers are encoded by opponent patterns of dopamine and serotonin release in essential tremor, but not Parkinson's disease, patients. We also demonstrate that these changes in serotonin signaling comprise a neurochemical boundary that subsegments these two neuromotor diseases. Our combined results point to a neural signature of altered reward processing that can be used to understand the signaling deficiencies that underwrite these diseases.
