    Background:

    • Perivascular noradrenergic nerves are crucial for regulating vascular function.
    • Quantifying nerve density and varicosity distribution is essential for understanding neurovascular diseases.
    • Traditional methods for nerve quantification have limitations in resolution and speed.

    Purpose of the Study:

    • To develop and validate image analysis methods for precise measurement of perivascular noradrenergic nerves.
    • To compare the efficacy of image analysis with existing techniques for fluorescence quantitation.
    • To apply image analysis to investigate sympathetic nerve dynamics in various physiological and pathological states.

    Main Methods:

    • Utilizing fluorescence histochemistry to visualize perivascular noradrenergic nerves and their varicosities.
