Why Do Scents Often Trigger Vivid, Emotionally Charged Memories?

💡 The Answer

• Olfactory signals have a direct pathway to the amygdala and hippocampus, bypassing the thalamus.
• This unique neural wiring makes smell-evoked retrieval more immediate and emotional.
• The phenomenon is called the Proust effect, named after the writer Marcel Proust.
• Smell can trigger memories that are decades old with remarkable clarity.
