Chronic chemogenetic manipulation of ventral pallidum targeted neurons in male rats fed an obesogenic diet.

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
Current treatments for obesity do not reliably reduce body weight over time. New interventional strategies, including chemogenetics, carry promise based on preclinical animal studies. Here, we focused on the ventral pallidum (VP) due to its clearly established role in eating behavior. Chronic inhibitory or excitatory chemogenetic activation was used to modulate the activity of VP-targeted neurons in rats on an obesogenic diet. Based on studies using acute VP manipulations, we hypothesized that VP inhibition would decrease weight gain, while VP stimulation would increase weight. Instead, both manipulations caused weight gain over time, and in a manner not clearly linked to consumption levels. We theorize that the complex reciprocal feedback between ventral striatal structures and metabolic centers likely underpin our unexpected findings. Regardless, this study suggests that the result of strategies to prevent obesity with chronic neuromodulation could be difficult to predict from prior preclinical studies that have used acute interventions.
