Paper: doi.org/10.1101/2025...

Using combined MEG and eye-tracking, we report new evidence suggesting that when eye movements are phase-locked to alpha oscillations in neural activity, the brain can better process and represent the visual objects that the eyes land on, supporting their encoding in memory.

During natural reading with eye movements, the left posterior fusiform cortex reflects both fixated and upcoming words in parallel—and distinguishes whether an upcoming word is skipped or fixated. A new preprint from Graham Flick @grahamflick.bsky.social!

These results suggest that during visual reading, word recognition and integration begin parafoveally, underpinned by the left occipito-temporal system.

AND this system appears to be the first port of call where word processing may rapidly exert downstream influences on eye movement behaviours.

What about word skipping? Here, we examined parafoveal processing of words that were skipped vs. fixated.

This revealed widespread parafoveal effects of frequency and surprisal before skipping, with significantly larger effects preceding skipped words in the left fusiform and middle temporal gyri

We identified putative generators of these influences in left occipito-temporal and ventral temporal areas.

These effects began in posterior areas during parafoveal word processing and shifted anteriorly when the word was fixated.

Matching past work, 2 properties significantly influenced fixation durations: a given word's frequency and it's surprisal in the current context.

Next, we asked where and when these properties influenced neural activity, time-locked to fixation onsets

To try to answer this, we recorded brain activity and eye movements with simultaneous MEG and eye-tracking, while participants naturally read short stories.

This allowed us to analyze neural activity time-locked to more than 22k gaze fixations

As a visual reader moves their eyes across this sentence, they will linger on certain words longer than others, and skip some entirely.

How does the brain make these decisions, based on the incoming linguistic input, in tens or hundreds of milliseconds?

Reading ahead: Localized neural signatures of parafoveal word processing and skipping decisions Visual reading proceeds fixation-by-fixation, with individual words recognized and integrated into evolving conceptual representations within only hundreds of milliseconds. This relies, in part, on in...

Sample images sorted by evoked valence/arousal and memorability. Scene images were selected to span a wide range of average valence and arousal scores. The figure above shows examples of memorable and forgettable images from across the spectra of valence and arousal. Examples include a tornado (negative and memorable), pollution from a factory (negative and forgettable), a field of sunflowers (positive and memorable), a frosty field in early morning (positive and forgettable), a car crash (high arousal and memorable), and a mountain scene (high arousal and forgettable).

How is the memorability of an image influenced by how it makes us feel?

@hartwakeland.bsky.social created an image set (VAMOS) of over 900 scene images, along with their valence, arousal, and memorability ratings. They then showed that *moderately* negative images are more memorable!

Nice study showing that memories for new speech + hand movement associations are linked to the specific words they were learned with, suggesting that "...word or gesture production might reactivate an entire co-speech gesture memory engram"

Please, spread!
