    Area of Science:

    • Neuroscience
    • Surgical Techniques
    • Animal Models

    Background:

    • Cerebrospinal fluid (CSF) analysis is crucial for neurological research.
    • Previous methods for CSF collection in rodents can be invasive or technically demanding.

    Purpose of the Study:

    • To present a straightforward and cost-effective technique for serial CSF sampling.
    • To enable collection of substantial CSF volumes from the cisterna magna in unanesthetized rats.

    Main Methods:

    • A novel cannulation method targeting the cisterna magna.
    • Utilized readily available and inexpensive materials for cannula construction.
    • Procedure performed on unanesthetized rats to minimize physiological stress.

    Main Results:

    • The described technique allows for repeated CSF sample collection.
    • Cannulas maintained patency over extended periods.
    • Significant volumes of CSF were successfully obtained.

    Conclusions:

    • This method offers a practical and economical approach for rodent CSF sampling.
    • The technique is suitable for studies requiring longitudinal CSF analysis in unanesthetized subjects.
