We report here on a new method for the encapsulation and preservation of the central nervous system (CNS). The encapsulation material is a high performance, silicone dielectric gel adhesive that provides a stable environment without any significant visual distortion. This method is cheaper and simpler than plastination, can be repaired or changed after initial encapsulation, preserves fine detail, and can clearly demonstrate anatomical variations. The final result demonstrated a crystal‐clear view of the human central nervous system within a large acrylic capsule. From our experience, the system was found to be superior to both liquid and solid encapsulants. The specimen was completed over 2 years ago and has not shown any significant signs of change. The goal of this project was to create an anatomical model that was useful as an adjunct for teaching in the classroom and laboratory. It is the authors hope that this method can be extended to other anatomical specimens for their preservation and display.
