    Area of Science:

    • Neuroscience
    • Histology
    • Animal Research

    Background:

    • Traditional brain fixation methods can be time-consuming.
    • Efficient tissue processing is crucial for timely research outcomes.

    Purpose of the Study:

    • To develop a rapid in vivo brain hardening technique for rats.
    • To enable immediate sectioning and slide preparation.

    Main Methods:

    • In vivo perfusion of rat heads with 50% formalin.
    • Subsequent perfusion with 10% sucrose-formalin.
    • Immediate sectioning using a freezing microtome.
    • Routine staining of unmounted sections.

    Main Results:

    • Instantaneous hardening of the rat brain achieved.
    • Successful immediate sectioning post-perfusion.
    • Excellent quality histological slides prepared within one hour.

    Conclusions:

    • This method significantly accelerates the process of preparing rat brain histology slides.
    • The technique allows for rapid analysis of brain tissue.
    • Offers a time-efficient alternative for neuroscience research requiring immediate tissue examination.
