Innovative, Simple Models for Teaching Neuroanatomy Using the Elnady Technique

Area of Science:

• Veterinary Anatomy
• Neuroscience Education

Background:

• Plastination is crucial for neuroanatomy education but is costly and complex.
• Existing methods for brain slice plastination present significant challenges.

Purpose of the Study:

• To introduce the Elnady Technique, an innovative, simple, and cost-effective method for plastinating animal brain slices.
• To provide realistic, durable, and flexible neuroanatomical models for educational and clinical interpretation purposes.

Main Methods:

• The Elnady Technique involves enveloping brain slices in lamination sheets using an electric iron or transparent plastic via an impulse sealer.
• This method is applied to various domestic animal brains.

Main Results:

• The process is fast, effortless, and yields realistic, durable, odorless, soft, and flexible brain slice models.
• These models accurately represent three-dimensional (3D) neuroanatomical structures, highlighting gray and white matter contrast.

Conclusions:

• The Elnady Technique provides an invaluable, cost-effective tool for neuroanatomy education and interpretation of clinical imaging like computed tomography (CT) and magnetic resonance imaging (MRI).
• These ethically sourced plastinated models offer a viable alternative to animal dissection in practical classes.
