🚨 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):

Excited to share our new paper w/ @cibaker.bsky.social in @natcomms.nature.com linking active vision & memory!

We provide evidence that gaze reinstatement & neural reactivation are deeply related phenomena that jointly reflect the experiences constructed during recall. doi.org/10.1038/s414...

Huge thanks to my brilliant supervisor Tobias Staudigl (@tobiasstaudigl.bsky.social) for his guidance and support, to our amazing collaborators (Tzvetan Popov, Tara Beilner @tafgmcb.bsky.social, and others at LMU Munich), and to the participants and patients who took part in the study!

✅ In sum, our findings show that neglecting eye movements leads to an incomplete understanding of the alpha/beta subsequent memory effect. We advocate for new perspectives on interpreting the alpha/beta SME and on the function of alpha/beta activity in general (6/7).

📌 We also show that eye movements shape alpha/beta activity on a moment-to-moment basis and alpha/beta amplitude reductions can be explained by accumulated eye movements.

Here’s Experiment 1 as an example (5/7):

📌 By manipulating eye movements, we provide causal insights that eye movements drive alpha/beta power reductions (4/7).

📌 When participants attempted fixation, the alpha/beta subsequent memory effect disappeared, while visual exploration continued to modulate alpha/beta power (3/7).

📌 The degree of visual exploration was the consistent and robust modulator of alpha/beta power reductions.

The figure below shows this in Experiment 1 during free viewing. Check out the preprint for consistent findings across all 4 experiments (2/7).

📢 New preprint from the lab:

We are very excited to report the discovery of an oscillation in the Central Thalamus using rare direct recordings of human thalamic electrophysiology.

The novel oscillation is tightly coupled to specific, natural states of consciousness.🧵

🧠🚨 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.

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...
