one of the cool things about rock climbing as a hobby is that you gradually lose the ability to be recognized by fingerprint scanners

A multisensory, bidirectional, valence encoder guides behavioral decisions A key function of the brain is to categorize sensory cues as repulsive or attractive and respond accordingly. While we have some understanding of how sensory information is processed in the sensory pe...

How is valence computed in the brain? Check out our new preprint about a single cell that integrates excitatory and inhibitory input across modalities according to valence and impacts behavioral decisions. An exciting collaboration across many labs. Enjoy reading!

Amazing work on bee photoreceptors by my good friend @gkolyfetis.bsky.social!

How do brains make decisions when faced with multiple, potentially conflicting cues? In our latest preprint, we show how #zebrafish use an additive strategy and process multiple visual features through anatomically distinct parallel pathways tinyurl.com/mvkn8em9 Thread 👇

It’s surreal to think that every neuron and synapse in the fly brain + cord that was dissected almost five years ago (the photo’s still on the lab slack!) is now just a click away on Codex codex.flywire.ai?dataset=banc. This wouldn’t have been possible without the incredible team behind it!

@mblscience.bsky.social Visual Neuro course

Day 1 of the Visual Neuroscience course at the MBL in Woods Hole. The legendary John Dowling and Michael Do, both from Harvard, gave fabulous intro lectures on photoreceptors And the lab is humming! Can’t wait for day 2!

The Behavioural Neurobiology Summer School in Kosovo is back for the 2nd year and after just a few days we already made it onto live TV! For anyone who speaks Albanian, you can check out the full broadcast here: shorturl.at/kpUzp 🎙️

Seeing the world through the lens of oscillations - we are delighted to share our new paper where we demonstrate that anatomically resolved oscillatory bursts reveal dynamic motifs of thalamocortical activity during naturalistic stimulus viewing (doi.org/10.1016/j.ne...).

Memory by a thousand rules: Automated discovery of functional multi-type plasticity rules reveals variety & degeneracy at the heart of learning Synaptic plasticity is the basis of learning and memory, but the link between synaptic changes and neural function remains elusive. Here, we used automated search algorithms to obtain thousands of str...

We just pushed “Memory by a 1000 rules” onto bioRxiv, where we use clever #ML to find #plasticity quadruplets (EE, EI, IE, II) that learn basic stability in spiking nets. Why is it cool? We find 1000s!! of solutions, and they don’t just stabilise. They #memorise! www.biorxiv.org/content/10.1...

From Morphology to Computation: How Synaptic Organization Shapes Place Fields in CA1 Pyramidal Neurons The synaptic mechanisms driving feature selectivity in specific neuron types remains a fundamental and unresolved challenge in neuroscience. In hippocampal CA1 pyramidal neurons (PNs), the development...

New collaborative preprint with Losonczy Lab and Polleux Lab!
How does synaptic organization shape place fields in CA1 Pyramidal Neurons?
We mapped thousands of synapses & showed that clustering of excitatory inputs is key for tuning.

Housing and husbandry factors affecting zebrafish novel tank test responses: a global multi-laboratory study Lab Animal - This Article presents the results of a global multi-laboratory study assessing the effects of housing conditions and experimental settings on novel tank test responses in adult zebrafish.

Just out in Lab Animal: our new global multi-lab zebrafish study is live! Housing and husbandry variables can significantly alter zebrafish anxiety-like behaviour. This is a call for better reporting and #standardisation in #zebrafish research. @uniofsurrey.bsky.social

Correlative light and electron microscopy reveals the fine circuit structure underlying evidence accumulation in larval zebrafish Accumulating information is a critical component of most circuit computations in the brain across species, yet its precise implementation at the synaptic level remains poorly understood.
