Network dynamics for sensory prioritization: Functional connectivity related to individual sensory weighting of vision versus proprioception during upper limb control https://www.biorxiv.org/content/10.1101/2025.07.31.667932v1

Delighted to share this paper, now published in @arvoinfo.bsky.social. With @spk3lly.bsky.social‬ and Anna Geuzebroek we explored differences in visual cortical responses for pattern pulses and pattern reversals. Here's the link:

Visual stimulus-evoked blood velocity responses in individual human posterior cerebral arteries measured with dynamic phase-contrast functional MR angiography https://www.biorxiv.org/content/10.1101/2025.07.20.665220v1

We cover a broad range of topics, including:
- using fMRI to predict recovery in visual disorders
- eye-tracking to measure visual function
- the auditory system and tinnitus
- sight restoration therapies

Hope to see you there!

Sensory eye dominance varies over the horizontal axis of the visual field: left eye dominance for the right visual field; right eye dominance for the left visual field.

Surely you know about eye dominance. You probably don’t know it’s not a unitary phenomenon: in this paper I show that sensory eye dominance varies over the visual field. In the Discussion I propose an explanation for why this variation might exist. Curious? Read it here: doi.org/10.1167/jov....

Model mimicry limits conclusions about neural tuning and can mistakenly imply unlikely priors Nature Communications - Model mimicry limits conclusions about neural tuning and can mistakenly imply unlikely priors

Who doesn't like a good model of the brain? Yet, from simple regression to neural nets, some limitations keep popping up (e.g., overfitting) @mjwolff.bsky.social & I saw some cool but puzzling data, ran a quick analysis & found one such limitation: model mimicry. Now in #naturecommunications &🧵below

Just finished my poster for OHBM. The results blow the discussion about V2 & V3 layout wide open. We find hemispheric asymmetry!
Fantastic work by my student Ruby Barahona, collaboration with the also fantastic @felenitaribeiro.bsky.social and Noah Benson.

How is high-level visual cortex organized?

In a new preprint with @martinhebart.bsky.social & @kathadobs.bsky.social, we show that category-selective areas encode a rich, multidimensional feature space 🌈

Functional organization of visual responses in the octopus optic lobe Pungor et al. use calcium imaging to measure visually evoked response properties in the cephalopod central nervous system. They demonstrate shared and novel aspects of visual function in the octopus, ...

This group did visual receptive field mapping in the octopus occipital lobe and now I'm obsessed with studying the computations involved in cephalopod vision.

Excited to share some new results that show how retinotopic mapping of disparity in mouse visual areas totally falls apart with monocular deprivation (MD). We also show how that disorganization results in depth discrimination deficits in the MD mice. #neuroscience
