ANECDOTE

Preserved Brains

  • Archaeologists occasionally find preserved brains in bodies hundreds or thousands of years old, even when other soft tissues have decomposed.
  • One example is St. Hedwig of Silesia, who died in 1243, whose brain was found preserved and attributed to divine power.
INSIGHT

Brain Preservation Hypothesis

  • Iron may catalyze cross-links between proteins and lipids, creating stable molecules that resist degradation.
  • This process might be similar to what happens in neurodegenerative diseases, offering potential insights into brain aging.

Prevalence of Preserved Brains

  • Preserved brains are more common than previously thought, but they can be easily missed during excavations.
  • They are often the same color as soil, leading archaeologists to unintentionally discard them.
