Adding to the recent Nature-Nurture debate: very excited to share our preprint biorxiv.org/cgi/content/shor… where we explore a nature-nurture-transform in the visual cortex.
In short: it could be both – a dynamic reorganization!🧵

Mark your calendars: During @BernsteinNeuro conference 2024 on Sept 29th a very talented post doc in my @IntBioPhysics group Lisa Blum - Moyse will be giving a talk on our latest work developing theories of social foraging under different environmental conditions . The talk is part of the workshop on algorithms and neural mechanisms of social and collective decisions organised by @BahlLab and @KatrinVogt3 bernstein-network.de/bernste…

Like ripples in the sand: cerebral cortex forms spontaneous patterns. A study by Matthias Kaschube @fias_science & @umnmedschool shows, that the cortex self-organizes during development forming highly structured activity patterns. fias.news/en/news-publicity/…, nature.com/articles/s41467-0…

We survey generative models that can be trained on time series to mimic the behavior of the neural substrate.

Very excited to be at #CNS2023 in Leipzig!
I’ll present our work on developing reliable representations in the talk session Monday afternoon, 2:50 pm - and new additional optogenetic stimulation results in workshop No. 3 on Tuesday morning.

Es war ein langer Weg, aber jetzt ist es geschafft. Gestern haben wir im Rat des Instituts für Philosophie der HU Berlin einstimmig beschlossen, unsere Personalstruktur grundlegend zu reformieren. Ein 🧵 dazu, was das bedeutet. 1/12

Very excited to share our new preprint on visual processing in the octopus! Led by Judit Pungor @traceofpink, together with @jsongco_ and @climbing_octo, we measured the functional organization of visual responses in the octopus brain. 🐙👁️

Impressive symposium on excitation-inhibition balance @NeuroforumNWG! Great talks by @GjorJulijana, @thmspfffr, @_rdgao, Anna Levina & Irina Pochinok. Thanks @SebBitzenhofer & @chini_mattia from @HanganuOpatzLab for organizing it 👏!
Last preparations for my talk in symposium S36 "Transformations of visual representations from retina to cortex" at #GoeMe23.
Many thanks to @HeleneSchreyer @kolofonium for organizing such a great lineup and inviting me as early career speaker!
Friday, 14.40 in Hall 104
the largest poster of my life so far!
Exploring Nature vs Nurture - what happens to sensory representations at the junction of endogenous and experience-driven mechanisms.
Say hi today at #cosyne23 at poster 7 (and scout for free drink tickets for the dance party afterwards) – at Montréal, Québec

Happy to share our preprint on how much neuroimaging data is needed to predict intelligence. We also introduce a new prediction method that outperforms previous ones on that task. Go check it out
📢 NEW PrePrint🥳: How Much Neuroimaging Data do we Need to Predict Complex Human Traits❓>> We developed a new ML-based Predictive Modeling Framework for Neuroscience🧠 + show that IQ scores can be predicted from as few as 20 time frames fMRI data‼️ doi.org/10.1101/2022.12.23.5…
I'm also still at #SfN22 and happy to discuss!
*and for those that saw me drawing lines during my talk on Saturday: this has all the plot elements that went missing 😌🙇

Overall, this model suggests that such nature-nurture transforms could involve realigning feedforward and recurrent networks in a fashion that is optimal for amplifying the novel activity patterns induced by the onset of visual experience.
