NSD has profoundly shaped vision science. Inspired by it, we combined fMRI and Neuropixels to build a macaque dataset with 1,000 natural images.

We’re excited to share Triple-N and welcome feedback from the community!

[MoonL-LiYipeng @MoonL620922]

(1/6) Thrilled to share our triple-N dataset (Non-human Primate Neural Responses to Natural Scenes)! It captures thousands of high-level visual neuron responses in macaques to natural scenes using #Neuropixels.

Can you see a monkey face in the middle image? Normally, when you turn a face upside down, it’s still a face. But rotating a visual anagram like this can change what it appears to depict. We asked how🐒🧠represents these rotation-dependent changes in object interpretation. (1/n)

Triple-N dataset published in Nature Neuroscience 🧠Combined fMRI functional mapping + dense NHP neural recordings to unpack primate visual encoding of natural stimuli. Open dataset available for the field. Grateful to all collaborators.

3-176: Formation of word-selective areas in macaque inferotemporal cortex through visual experience

We used wide-field calcium imaging to track how visual experience shapes a macaque cortical region analogous to the human VWFA.

I am deeply excited to share that I will be joining @AsteraInstitute to start a new effort to understand how the brain generates consciousness and intelligence.

#SFN2025 We are presenting three posters and one talk, covering object color knowledge, how word learning shapes macaque IT, the internal functional structure of face areas, and how IT represents movies. Come say hi!

Takeaway:
LOC flexibly reorganizes its spatial coding depending on task demands.

Perception: contralateral
VWM: bilateral & distributed

This spatial reformatting may be key to how the brain maintains object info beyond the moment it is seen.

Excited to share our new paper:
Spatial Reorganization of Object Representations in High-Level Visual Cortex Distinguishes Working Memory from Perception
https://t.co/1UehQc9XMA

[Pinglei Bao @bobking]

To test how widespread this expansion is, we performed ablation decoding + searchlight RSA.

The result?
VWM representations extend to ipsilateral patches not used during perception, but still preserve sensory-like similarity structure.

WM ≠ perception

#VSS2025 The B-Lab from Peking University will be presenting the following talks and posters at VSS this year.

Unfortunately, I won’t be able to attend in person due to visa issues—but my thoughts are with all my friends and colleagues at the conference.

[Yale Neuroscience @YaleNeuro]

In a new study published in @NeuroCellPress, a team of @YaleMed researchers led by @neural_nandy & @mon_sci showed that visual clutter 👁️ affects the efficiency of information flow in the brain! 🧠 @YaleNeuro @YalePsych @YalePsychology
