Bringing Vision Science Closer to the Real World Vision science has demonstrated considerable success in characterizing early- and mid-level visual processes through reductionism and tightly controlled experiments. However, an understanding of high-...

I had five wonderful years in Giessen, both scientifically and personally. The vision science research environment at JLU has gone from strength to strength. A really incredible opportunity if you're interested in experimental perception science!

Why do children struggle to recognise objects in cluttered scenes more than adults? Our new paper looks at the development of visual acuity and crowding across childhood, and the way the visual system fine tunes our ability to see detail: www.nature.com/articles/s41...

Tuning metaplasticity in the adult visual cortex using flickering light https://www.biorxiv.org/content/10.64898/2026.02.16.706197v1

Neural tuning for ordinal processing: convergent patterns in human brains and artificial networks Processing ordinality, i.e., the rank of an item in a series such as 1st, 2nd, 3rd, etc., is a fundamental skill shared by humans and animals. While humans often use symbolic sequences like numbers or...

In sports, we celebrate 1st, 2nd, 3rd. Everyone else gets lumped together. Why?

Using 7T MRI, pRF modelling, and artificial neural networks, we show that tuning underlies ordinality perception, with most neural populations preferring early ordinalities.

Excited to announce the first paper of my PhD, which explores an inverse relationship between brain and retina complexity. We think this may reflect a more general trade-off between central and peripheral processing of sensory information. Read more here: jov.arvojournals.org/article.aspx...

Making Sense of Monitor Lizard Cognition: Ecological Drivers of Divergent Cognitive Evolution - Biological Theory Biological Theory - Monitor lizards, some of the largest and most ecologically diverse lizards, have traditionally received little attention in comparative cognition research. Although emerging...

For any one who might be curious as to why monitor lizards might have more sophisticated cognitive abilities when compared to many other closely related lizards here are a few evolutionary hypothesis. I'd more than happy to share a copy of the paper with anyone interested. Enjoy!

A Quantitative Benchmark of Visual Information in Human Brain Recordings Across fMRI, MEG, and EEG https://www.biorxiv.org/content/10.64898/2026.01.11.698841v1

Neural representations of visual memory in inferotemporal cortex reveal a generalizable framework for translating between spikes and field potentials Translating neurophysiological findings requires understanding the relationship between common measures of brain activity in animals (spiking activity) and humans (local field potentials, LFP). Prior ...

🚨 New preprint!

Why do some insights from spikes translate to field potentials while others don't? In this paper we compare visual memory representations in spikes and LFPs to propose a general framework that answers this question.

BOLD signal changes can oppose oxygen metabolism across the human cortex, Nature Neuroscience

fMRI signals “up,” but neural metabolism might be going “down.”

In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes.

Your brain transforms what you see into first-person, body-referenced codes: A previously unknown bridge between vision and touch.

In this preprint, we concurrently fit the HRF alongside pRF parameters doi.org/10.1101/2025...

- HRF varies between visual areas
- HRF also varies with pRF stimulus designs (due to nonlinearities?)
- Esp. when fitting complex models this can skew results a lot!
