This research aims to evaluate how different brain fixation methods affect ultrastructural preservation in animal models.
Two fixation methods tested: immersion fixation and transcardial perfusion.
Six conditions vary time and pressure in fixation processes investigated.
Ultrastructural analysis conducted using light and electron microscopy.
Immersion fixation resulted in poor morphological preservation and notable artifacts.
Transcardial perfusion with physiological parameters achieved superior preservation, while deviation caused artifacts.
No major differences found between transcardial perfusion groups.
