Decoding human olfaction by high heterologous expression of odorant receptors detecting signature odorants Emter et al. improve in vitro expression of odorant receptors (OR) by engineering the C-terminal domain. With a library of engineered ORs, they discover ORs for signature odorants, which they relate…

Scientists at Firmenich buff.ly/jq1TyYa and now Givaudan buff.ly/u2gP5Ow report several olfactory receptors that appear to map cleanly onto specific odor notes (earthy, grapefruit, woody, etc.). 🧪

Respiration facilitates behaviour during multisensory integration The brain processes information from the external environment alongside signals generated by the body. Among bodily rhythms, respiration emerges as a key modulator of sensory processing. Multisensory ...

The Lasting Cognitive Effect of Smell on Memory Researchers, exploring what happens in the brain after exposure to certain smells, found that that even brief odor cues have a lasting effect

Just a whiff of certain smells can instantly take me back to my childhood... Read a new Q&A with Joan Tarrida Vidal about the lasting cognitive effects of smell:

YouTube video by Xiaojin Ma using PsychoPy to build a cognitive psychology experiment from scratch

I recorded a step-by-step tutorial of programming experiments in PsychoPy for undergrad thesis students in my lab. Sharing it here for anyone new to programming in psychology, or those transitioning to PsychoPy from other software. www.youtube.com/watch?v=CMJX...

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...

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.

🧵Thread (6/6)

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.

#Cognition #EEG #Memory
🧵Thread (5/6)

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.
🧵Thread (4/6)

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.
🧵Thread (3/6)

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.
🧵Thread (2/6)

🧠👃 Can a _brief smell_ change how we remember something seconds later?

We used EEG + memory testing to show that odors trigger sustained brain activity—and shape memory for events happening after the smell disappears.

#Neuroscience #Olfaction
🧵Thread (1/6)

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?
🧵Thread (2/10)

🚨 New preprint alert!

Excited to share our latest work on alpha/beta activity, eye movements, and memory.

Across 4 experiments combining scalp EEG/iEEG with eye tracking, we show that alpha/beta activity directly reflects eye movements, and only indirectly relates to memory.

👇 Highlights (1/7):

Convergent transformations of visual representation in brains and models A fundamental question in cognitive neuroscience is what shapes visual perception: the external world's structure or the brain's internal architecture. Although some perceptual variability can be trac...

🧠🚨 How does the brain represent what we see? Is visual input transformed to form these representations in similar ways across people and even AI models like DNNs?

We explore these questions using fMRI and large-scale representational alignment analyses.

Very happy to announce that the latest work "Anticipating multisensory environments: Evidence for a supra-modal predictive system" from @alepebel.bsky.social @fuentemilla.bsky.social and myself has been published in Cognition!

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.

I would like to extend my gratitude to all the contributors who made this possible. @fuentemilla.bsky.social , Josep Marco-Pallarés, Manuel Moreno, Jordi Vidal and David Panyella.
