We identified how mechanical forces shape myelin development. The TMEM63A channel in oligodendrocytes converts physical cues into molecular signals that control myelin growth. Oligodendrocyte mechanotransduction channel TMEM63A regulates myelin sheath geometry: Neuron www.cell.com/neuron/fullt...

Motivated reasoning with confirmation bias: Sometimes “We don’t reason to discover the truth, we reason to justify what we already believe.”

Really nice work from the Holmes lab looking at amygdala astrocytes in fear memory and extinction! www.nature.com/articles/s41...

🎉 Great news! Our paper is now published in @naturecomm We identify a specific astrocyte ensemble that mediates THC-induced cognitive impairments during adolescence Huge thanks to our collaborators @marsicanolab @khakhlab @grandeslab 🔗 rdcu.be/eY0Or @jsromero.bsky.social @crismonteagudo.bsky.social

Scientific knowledge flourishes as a non zero-sum nature, nurtured by intellectual freedom and shared inquiry. However, this beauty is frequently undermined by systems that operate on zero-sum logic.

Elegance of a model lies in the simplicity of predicting a phenomena emerged based on intuitive believe 🤔, and understanding of the nature of reality captured by abstract imagination 💭 that are observed experimentally 👀, realised or discovered at a later stage.

New results! Computational models often rely on hand-crafted connectivity and imposed dynamics to produce traveling waves (TWs). We show how TWs can naturally emerge under biologically plausible conditions. Emergent Traveling Waves in Neural Circuits doi.org/10.64898/202... #neuroscience

Many cortical traveling waves spiral. Here's how and why. Cortical Field Model of Complex Spiral Traveling Waves doi.org/10.64898/202... #neuroscience

Wow !! Another RNN based #TravelingWave #TW mechanistic model for cortical computation. In future: 🌊 Prop > 🔙 Prop 🤩.

Delighted to share our first preprint of the year! A project that we're all really proud of in the lab led by @ossamaghenissa.bsky.social with @mathiasgua.bsky.social in which we set out to test the role of basolateral amygdala astrocytes in anxiety behaviour. www.biorxiv.org/content/10.6...
