Customizable artificial simulator for developing, planning, and training personnel on neurophysiology and surgical procedures in non-human primates.
Article in Journal of neuroscience methods, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundNeuroscience researchers often surgically implant hardware into model organisms to measure and manipulate neural activity. Designing and optimizing these procedures in non-human primates often requires sedated or euthanized animals. Artificial tissue technologies can reduce animal use in this process, but existing simulators do not include all relevant tissues and do not facilitate iterative design processes. NEW
methodWe created a comprehensive, customizable, and modular surgical simulator for neuroscience research. Our simulator incorporates artificial skull, brain, and soft tissues (skin and muscle) into one 3-dimensional model with adaptable components.
resultsIncorporating 3-dimensional soft tissues enabled surgical and implant design improvements, which may contribute to improving implant longevity, research outcomes, and animal wellbeing. Our modular design allowed researchers to rapidly prototype designs and exchange parts to reflect implant or anatomical changes across a study. Incorporating all relevant tissues also enabled surgical practice and improved communication with veterinarians. Our approach is low-cost (a few hundred dollars) and uses readily available tools like 3D printing. We also provide models of different non-human primate species to increase access to our approach. COMPARISON WITH EXISTING
methodsOur method improves upon past surgical simulators for neuroscience research by: adapting existing skin and muscle artificial tissue technologies to more accurately represent cranial 3-dimensional geometry, incorporating models of all tissues relevant for implant design, and introducing modular designs that increase flexibility/customization.
conclusionsWe found that this surgery simulator was an inexpensive tool that was useful for planning and practicing surgical procedures, as well as prototyping new neuroscience experiment hardware.
