Whole Central and Peripheral Nervous System Mice Dissection

Area of Science:

• Neuroscience
• Anatomy
• Animal Models

Background:

• Animal models are crucial in neuroscience research.
• A comprehensive, step-by-step protocol for dissecting the entire rodent nervous system is currently unavailable.
• Existing methods only allow for the separate harvesting of specific nervous system components.

Purpose of the Study:

• To provide a detailed protocol for the complete dissection of the murine central and peripheral nervous system.
• To offer a comprehensive schematic of the rodent nervous system.
• To facilitate a more holistic study of nervous system anatomy and pathophysiology in animal models.

Main Methods:

• A 30-minute pre-dissection step to isolate the intact nervous system within the vertebra, free of viscera and skin.
• A 2-4 hour micro-dissection process under a microscope.
• Exposure of the spinal cord and thoracic nerves, followed by the removal of the entire central and peripheral nervous system.

Main Results:

• A robust, step-by-step protocol for the complete dissection of the rodent nervous system.
• Detailed pictures and a schematic of the central and peripheral murine nervous system.
• Successful isolation of the intact nervous system for further analysis.

Conclusions:

• This protocol significantly advances the ability to study the nervous system globally in rodent models.
• Enables detailed anatomical and pathophysiological investigations.
• Facilitates downstream analyses, such as histology for tumor progression studies in models like neurofibromatosis type I.
