We explain how responses to a mismatch between locomotion and optic flow can arise in V1. We propose they are a result of a cooperation between motor and visual areas to explain the perceived optic flow. Now out in Neural Computation:

An interesting question: Does cortex integrate different modalities already in the early levels of processing? We think yes, by distributing representations over multiple areas.

A big thanks to @kendmiller + for helping the #neuroscience community get its hashtag act together!

https://neuromatch.social/@kendmiller@qoto.org/109645950754401219

For neuro paper threads: sigmoid.social/about/more has already claimed #PaperThread and #NewPaper (the latter announcing a paper without a thread) for the AI community. I enjoy seeing their papers too, but we need a distinct tag for neuro papers. For a thread, ... maybe we want something simple like #NeuroPaperThread and #NeuroNewPaper?

Great idea Ken - let's do this.

➡️​​EVERYONE: BOOKMARK THIS! ⬅️​ and follow those hashtags. And then don't hold back. After all, it's what we all show up here for: to hear what you've figured out and learn from you.

There's a generational gap which I'm starting to experience more and more, where nearly everything I talk to my kids about — be it nuclear fusion, be it war in Ukraine, be it GPUs — they source with YouTube videos.

But I simply cannot ingest these. Watching a 1½ hours sequential display of maybe even valid statements but which you can't easily scan for useful information feels like watching TV in 1990's, especially that YT is frequently interrupted by ads. And specifically for that reasons I haven't had a TV at home since 2000's.

Videos are kind of OK fo a lecture, where the lecturer sequentially guides you through an unfamiliar topic. But a rather lengthy video to present a single point, that would otherwise fit on half of a printed page, which you can easily scan and locate relevant paragraphs as a matter of seconds?

Feels very much like a downgrade, sorry...

Across a bunch of scientist biographies, I noticed that a lot of scientists were part of a club to discuss science. It's usually something mostly informal that meets about once a month. Some scientists that I know were part of such clubs and developed ideas there are Norbert Weiner, Ramon y Cahal, Alan Turing, Pyotr Kapitsa, among others. Counting down to the new year, I'll be posting about the societies that have fascinated me.

#introduction 👋
I’m a neuroscientist & artist. I got into the brain biz from making art—it’s like running #vision experiments on yourself. #Color is an obsession, it connects the physical world with #perception, #cognition, society, so I think it’s a great tool to understand us. I taught #neuroscience at #wellesley, ran a lab at #MIT & now at #NIH #NEI #NIMH. #Science happens in teams & diversity improves teams, so I really value #diversity in science, at all levels, of all kinds. #watercolor

New work from the lab out in Cell today, by En Yang and colleagues:

A brainstem integrator for self-location memory and positional homeostasis in zebrafish

I’m a bit concerned that people’s threads on this platform might be biased, so I will hereby do my bit to correct for that:

Have a look at our new publication on @NatureComms@twitter.com! In this work, we exploit the information provided by a #SPADarray to push the optical sectioning and resolution of #imagescanningmicroscopy to its limits.

Out today, my short piece in Nature Medicine about what scientists can do as authors to combat misinformation and disinformation about their own work.

@PhiloNeuroSci

I wonder what one might expect for vision if we delete the 90% or so of the retinal ganglion cells that project to the LGN, leaving only the other 10% to signal the brain?

Perhaps an impoverished form of vision that is unlike intact sensation? Over time, we might learn how to use the residual signals in helpful ways.

Perhaps this is an engineer’s view, without much philosophy. Is there a connection to philosophy in there?

#introduction

Hi everyone!

I am a neuroscientist (postdoc) in Botond Roska’s lab at the IOB in the beautiful city of Basel. During my PhD in Sonja Hofer’s lab at the SWC in London I studied the role of the ventral lateral geniculate nucleus (vLGN) in visually evoked escape behaviour. In general, I am interested in how the brain processes sensory stimuli and how experiences and internal mental states influence sensory information processing.

Looking forward to meeting you all!

Hello Mastodon! #introduction 👋​

I'm a cognitive neuroscientist 🧠​🔬​💻​ at the psychology department in Leiden, The Netherlands 🇳🇱​🌷​

I research how we make decisions 🔀​ and how our brains change as we age 👵​ (both in 🐁​ and 👩​)

Beyond brains, I care & post about #feminism, #openscience and #climateaction 🌍​

Happy to be here!

#introduction I am a professor at Penn and also co-director of the CIFAR Learning in Machines and Brains program. I like to think about neuroscience, AI, and science in general. Neuromatch. Recently, much of my thinking is about Rigor in science and I just started leading a large NIH funded initiative community for rigor (C4R) that aims at teaching scientific rigor.

My interests are broad: Causality, ANNs, Logic of Neuroscience, Neurotech, Data analysis, AI, community, science of science

🚨🚨🚨NEW PREPRINT🚨🚨🚨

A big mystery in brain research is what are the neural mechanisms that drive individual differences in higher order cognitive processes. Here we present a new theoretical and experimental framework, in collaboration with @SussilloDavid, Valerio Mante, Mikio Aoi, and Jonathan Pillow.

Hello, brave new world. I’m a scientist who’s passionate about open source code, democratization of AI, and mice playing video games… follow here for science, hot takes, and general thoughts on academia and tech 🤗

Hello Mastodon peeps 👋! This is what it looks like across hundreds of neurons in prefrontal cortex when a monkey starts dozing off.

#introduction

I am a researcher working at the interface of artificial intelligence and neuroscience. I wear two hats.

🎩 I work at Meta Reality Labs, thinking about neuromotor interfaces.

🤠 I am an adjunct professor at Stanford, where I think about neural dynamics and how they give rise to computation and behavior.

🙏 Deep apologies for doing this twice, but I moved servers. Shouldn't happen again.
