==Neuropathological dissection (autopsy)==
Brain fixation after removal: Usually 14 days
*Check brain for:
** Lesions
** edema (might be not visible but tissue is softer than normal)
** hemorrhage
** Discolorations
** Asymmetry (midline shift)
** herniation (subfalxial, uncal, tonsillar)
** vascular abnormalities
