Modulating inhibitory synaptic plasticity to restore basal ganglia dynamics 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
Parkinson's disease is characterized, in part, by hypoactivity of direct pathway inhibitory projections from striatum to the globus pallidus internus (GPi) and indirect pathway inhibitory projections from globus pallidus externus (GPe) to the subthalamic nucleus (STN). In people with Parkinson's disease (n = 32), we explored the potential use of intracranial stimulation for eliciting long-term potentiation (LTP) of these underactive pathways to produce improvement of symptoms that persist beyond stimulation cessation. During GPi deep brain stimulation (DBS) surgery, we found strong evidence (P < 0.05; BF10 > 10) of increased amplitudes of hand movements and striato-GPi evoked potentials before versus after high-frequency microstimulation. In a small sample of outpatients with sensing-enabled GPi-DBS, we found anecdotal evidence (P < 0.10; BF10 > 1) of improved hand movements and attenuated beta frequency oscillations. In STN, enduring behavioural effects, potentiation of GPe-STN projections (intraoperative), and decreases to beta oscillations (extraoperative) were not observed. Our findings support that LTP-like effects in GPi may produce motor improvements that extend beyond stimulation cessation, while the lack of effects in STN suggests the need for optimizing stimulation paradigms for effective LTP induction. These findings nevertheless highlight the potential of LTP-based strategies for sustained therapeutic benefits, which may be useful for mitigating DBS side-effects and optimizing battery usage.
