Excited to share our new paper!
By combining EEG and eye-tracking, we found that relational memory retrieval is supported by two distinct neural processes across sequential fixations: An early, general theta increase and a target-selective alpha decrease.

This study reveals how eye movements and neural oscillations jointly shape relational memory retrieval. By linking distinct theta and alpha dynamics across fixations to the retrieval of goal-relevant...

New study out today in Nature Comms: www.nature.com/articles/s41..., in which we set out to test whether ultrasound could influence the reward-related learning computations of the nucleus accumbens, building on decades of work on dopaminergic prediction error and reinforcement learning. And it did.

Decoding performance (MVPA) better for OPM-MEG than SQUID-MEG 😎. The improved spatial specificity of OPM-MEG due to the reduced brain-sensor distance is key. And more sensors (beyond 40) don't improve decoding.

If you're interested in the cognitive neuroscience of memory feel free to email me!

I do experimental psychology, brain imaging (fMRI and MEG) and a bit of modelling. Lab is doing stuff on forgetting, aging, schemas, and event boundaries, but we're not limited to that.

We show that the hippocampus detects mismatches between ongoing experiences and episodic memories but not generalised schematic knowledge.
