Egg Model Training Protocol for Stereotaxic Neurosurgery and Microelectrode Implantation

Area of Science:

• Neuroscience
• Surgical Training

Background:

• Neurosurgery in animal models is crucial for neuroscience research.
• Existing training methods lack a standardized protocol for small animal neurosurgery.

Purpose of the Study:

• To develop and present an egg model training protocol for stereotaxic surgery.
• To provide a viable alternative for practicing neurosurgical techniques without live animals.

Main Methods:

• Utilized a boiled egg as a model.
• Employed standard stereotaxic neurosurgery equipment and materials.

Main Results:

• The eggshell thickness approximates that of small animal skulls (mice, rats, primates).
• Trainees can practice craniotomy drilling, dura mater removal, and electrode implantation.

Conclusions:

• The egg model effectively simulates the neurosurgical environment for training.
• This protocol supports animal replacement and welfare by reducing the need for live animal training.
