The new episode of the Night Science Podcast is a must-listen! Art professor Lois Hetland wrote a classic book about the “studio habits of mind” – observe, reflect, envision, express engage & persist, stretch & explore, craft & connect – and we explore how these relate to scientific process!

Happy to share a new preprint from my PhD thesis! “A novel framework for expanding RNNs with biophysical detail to solve cognitive tasks” 🧠💻 📝 www.biorxiv.org/content/10.6... @jonescompneurolab.bsky.social
Multipanel figure illustrating the key components of the paper: 1) biophysical reservoir computing where a network of biophysically detailed excitatory and inhibitory neurons are randomly connected, receive a brief input, and produce a sustained spiking pattern in response, 2) an illustration of the task the biophysical reservoir computer is trained on: a simplified working memory task where the network must produce distinct fixed point attractors in response to different inputs.
