Episode notes
Smell and Memory
- Smell signals bypass the brain's thalamus, unlike other senses.
- This allows smells to directly reach areas responsible for emotion and memory, creating a strong link.
Emotional Impact on Smell Memory
- The direct link to emotional centers strengthens smell-memory connections.
- Stress hormones like cortisol heighten sense of smell, further intensifying memories tied to smells.
Seasonal Smell Sensitivity
- The olfactory system works differently in winter compared to summer.
- It becomes more sensitive in winter due to fewer airborne odorants, enhancing our ability to detect faint smells.
