Modulation of Non-Rhythmic Temporal Prediction by Subthalamic Nucleus Deep Brain Stimulation (STN-DBS) in Parkinson's Disease.

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
backgroundAccurate temporal prediction, essential for adaptive motor behavior, relies on corticobasal ganglia circuits. In Parkinson's disease (PD), both motor and non-motor functions are impaired. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) effectively alleviates motor symptoms, but its effects on non-motor domains, like temporal prediction, remain less understood.
objectiveThis study aimed to investigate how STN-DBS influences temporal prediction performance and its underlying oscillatory dynamics in PD patients, with a particular focus on beta band power and delta band inter-trial phase consistency (ITPC).
methodsThirteen PD patients (5 female, age: 64 ± 5.7 years; disease duration: 11.8 ± 1.8 years) with STN-DBS performed a temporal prediction task with (DBS ON) and without (DBS OFF) stimulation, while 64-channel EEG was recorded. Twenty age-matched healthy controls completed the same task. Behavioral performance was assessed using psychometric functions and time-frequency analyses of electroencephalography (EEG) data on sensor and source-level examined beta power and delta ITPC.
resultsPD patients showed impaired temporal prediction, but DBS improved performance to a level comparable with controls. EEG revealed reduced beta suppression in PD patients during DBS OFF, while beta suppression in DBS ON was comparable with controls. Both DBS OFF and ON exhibited reduced delta ITPC compared with controls. In DBS ON, source-level delta ITPC was positively correlated with temporal prediction accuracy.
conclusionsSTN-DBS improves temporal prediction performance in PD, likely through modulation of beta and delta oscillatory activity. However, while DBS effectively improves behavioral performance, oscillatory mechanisms underlying temporal prediction remain only partially restored. © 2026 The Author(s).
