Summary:
– Brief odors → lasting brain activity
– Unpleasant odors → stronger neural persistence
– These states shape later memory confidence
Smells fade fast—but not in the brain.

Odor-induced Sustained Neural Activity during Memory Encoding
Abstract. How long do the neural and cognitive effects of a brief odor experience last? This study investigated whether short exposures to pleasant and unpleasant odors can induce sustained changes in...

The odor-triggered brain state didn’t blend with the image—it lingered until the picture arrived, affecting encoding.
🧠 These emotionally charged states act as context bridges, biasing later memory formation.

Using LDA, we decoded odor identity from EEG during the 6s delay.
✔️ BUT vs AIR: 5.4s of significant decoding
✔️ CAR vs AIR: 4.4s + late cluster
⏳ Odor neural states were maintained.

EEG showed that odors triggered sustained ERP activity, lasting seconds after odor offset.
❗Unpleasant odors (Butanol) led to stronger and longer responses.
This effect didn’t overlap with picture ERPs.

Participants smelled pleasant (Carvone) or unpleasant (Butanol) odors.
6s later, they saw a picture.
A day later: recognition test.
Unpleasant odors didn’t boost accuracy—but they _increased confidence_ in memory.

We combined EEG and a memory task to test whether pleasant and unpleasant odors trigger lasting neural states.
After a 6s delay, participants saw an image to encode.
📅 A day later, they did a surprise recognition test.
Goal: Do brief odors influence long-term memory?

Go check it out if you want to know more about how brief exposure to odor cues induced sustained neural activity in humans, with distinct effects on memory formation along the pleasantness dimension.
