We wrote a perspective piece on the emergence of hardcore (i.e. intense) big datasets in neuroscience and how it effects the way we do science with @elimerriam, @Tknapen and @eline_kupers! Let us know what you think! osf.io/kacb4

Pumped to share this work from my PhD, “A single computational objective drives specialization of streams in visual cortex”, just in time for the holidays! With the all star team @eshedmargalit , @cvnlab , @dyamins & @kalatwt 🔗:biorxiv.org/content/10.1101/… 🧵: 1/n…

A single computational objective drives specialization of streams in visual cortex

Human visual cortex is organized into dorsal, lateral, and ventral streams. A long-standing hypothesis is that the functional organization into streams emerged to support distinct visual behaviors....

1/ Excited to share a new NeuroAI preprint: “What can 1.8 billion regressions tell us about the pressures shaping high-level visual representation in brains and machines?” Led by Colin Conwell, with @_jacobprince_, @cvnlab, and @grez72. biorxiv.org/content/10.1101/…

What can 1.8 billion regressions tell us about the pressures shaping high-level visual representa...

The rapid development and open-source release of highly performant computer vision models offers new potential for examining how different inductive biases impact representation learning and emergent...

There is much discussion about capabilities of GPT models. But how accurate are such models as models of language processing in the 🧠? Here, we demonstrate that GPT is accurate enough to noninvasively drive and suppress 🧠activity in the language network of new individuals. 1/

Latest lab work in @NeuroCellPress. We review tasks, how tasks affect activity in the visual system, and call for incorporation of tasks into stimulus-computable models. w/ @rndenison @DLBarack @MichaelJArcaro @katebonnen doi.org/10.1016/j.neuron.202…

Latest lab work in @NeuroImage_EiC by @ofgulban. We release high-quality mesoscopic (0.35-mm) anatomical measurements in the living human brain. Clear laminar and vascular features. May help us better understand the nature of fMRI signals. doi.org/10.1016/j.neuroimage…

Latest lab work in @NatureComms. We leverage the large-scale Natural Scenes Dataset and encoding models to obtain unbiased estimates of voxel-level orientation tuning. Results demonstrate coarse-scale orientation preferences in V1. w/ @zviroth @elimerriam nature.com/articles/s41467-0…

We've posted this working draft on OSF arguing for the need of further validation of layer-specific fMRI as an accurate and robust marker of neural activity, but we are still refining the text. We welcome comments from the community.

New layer-fMRI preprint by @elimerriam and @cvnlab. It is an opinion piece criticizing the current practices, assumptions, and scientific stance of layer-fMRI as a research field. doi.org/10.31219/osf.io/f9vq…

I’m pleased to share a pre-print about activity in the visual word form area! @jdyeatman, @cvnlab and I found that words evoke larger responses when task-relevant than when ignored, but the opposite happens for non-letter shapes. biorxiv.org/content/10.1101/… (1/2)

Engaging in word recognition elicits highly specific modulations in visual cortex

The ability to read depends on a region in ventral occipito-temporal cortex known as the “visual word form area” (VWFA). The VWFA, which has several sub-regions, lies amidst a collection of areas...

Preprint! How does the brain make sense of the world? Using a variety of converging analyses and recurrent DNN modeling of large-scale 7T data, we propose that the visual system computes rich semantic scene descriptions, rather than category labels only.🧵 arxiv.org/abs/2209.11737

Visual representations in the human brain are aligned with large...

The human brain extracts complex information from visual inputs, including objects, their spatial and semantic interrelations, and their interactions with the environment. However, a quantitative...
