Neuroscientist in Berlin, raising two kids. I won't figure out how the brain works but I will die trying. Studying mice, men and machines. I tweet new papers

Predictive Routing: "There are no special error-detection circuits or mechanisms." There are instead pathways that are gated by predictions and thus can be activated by unexpected inputs. Amazing monkey electrophysiology work by Andre Bastos @MillerLabMIT biorxiv.org/content/10.110…

That is an amazing resource! Thank you for sharing. I would encourage to even put it into arxiv so that more people would find it. I hope you can publish this as a book in the long run.

Interested in how learning happens in our brains? Want to know how one could use this knowledge to enhance learning in machines and in the classroom? You will love the new book by @StanDehaene. We are "homo docens – the species that teaches itself" penguinrandomhouse.com/books/579922/h…

Modulation of plasticity: Place cell reorganization by input from locus coeruleus (LC) to hippocampus (CA1). Activation of LC-CA1 axons near the reward induces place cell overrepresentation, inhibition of them suppresses it. Kaufman, Geiller & Losonczy cell.com/neuron/fulltex…

Knowledge enhances perceptual processing. Here @m_heilb @D__Richter @MatthiasEkman and @flodlan show that word context boosts the representational fidelity of individual letters in early visual cortex & increases the coupling to the reading network. Great! nature.com/articles/s4146…

The brain represents multiple future outcomes simultaneously and in parallel. Cool new work by @DeepMindAI, with single-unit recordings from mice confirming the predictions coming from AI side. nature.com/articles/s4158…

Thanks. The talks are on the 22th and 25th of February. If Anna is interested then I'd be more than happy to include something from her!

People doing #neuroart I will be giving two talks about "art and the brain" in Estonia. I am looking for artful images of neurons. If you wish your work to be shown, please post it as a reply to this tweet. As an appetizer, here's #neuronart by Christian Ebner. Please RT! pic.twitter.com/zDOepspH0I

just to clarify: Albert and others did all the work, I am just the messenger who did not contribute to this work (besides offering Albert some chocolate now and then). I am just happy to be a part of the lab of @mattlark

During the last 2 decades there has been quite some work on rodent layer 2/3 neurons with similar techniques. But in principle it is of course possible that in some other species (primates) this phenomenon will one day be observed. So far it hasn't been.

(No offence to all the great computational people out there. As far as I know most of you would agree that real recordings are more awesome than just having a model. The goal is to bring the amazing recordings and the model together, just as done in this paper.)

:) But this is *real* stuff, real neurons, real currents and real spikes, so nobody can complain that Albert "simply made up" something in a model by tuning parameters etc :)

Brains are amazing. Our lab demonstrates that single human layer 2/3 neurons can compute the XOR operation. Never seen before in any neuron in any other species. Out now in @sciencemagazine. Congrats Albert, Tim @mattlark @YiotaPoirazi & CO science.sciencemag.org/content/367/64…

Hi! I don't think so. But he still got game and is still putting out great papers even without twitter :)

During my two years in the lab of @mattlark I have witnessed several major discoveries by my labmates. I want to remind young scientists (and mainly myself) that there is no easy way: discoveries take a lot of time, effort and you cannot force them to happen. Happy 2020!

Why you need a cortex? Back-to-back papers in @NeuroCellPress showing that cortex is necessary for learning about complex stimuli. Bathellier group shows this for appetitive learning, Letzkus group for fear learning. Amazing. cell.com/neuron/fulltex… & cell.com/neuron/fulltex…

that's serious stuff if you can start your abstract with the question "What is the function of cognition?". I wish there would be more papers like yours. Congrats!
