Fitting deep neural networks on the input-output function of many neurons with different morphologies and biophyiscal properties allows us to study the source of their complexity It turns out that more elaborate dendrites, more NMDA, and steeper NMDA nonlinearity are the main contributors to a neuron's I/O complexity Also, it appears that human neurons just happen to possess much larger and elaborate dendrites, higher levels of NMDA ion channels and the human variant of the NMDA ion channel has a steeper non linearity. Almost feels like a few hyperparameters were deliberately tuned
Our work comparing the I/O complexity of different neurons is published in PNAS! We know human neurons are larger than rat neurons, but are they more functionally complex? pnas.org/doi/10.1073/pnas.25… With @danielayoeli @DavidBeniaguev Chris de Kock, @mikilon & @Segev_Lab. (1/13)

Happy to share my new open source tool for exploring connected neurons in the #MICrONS dataset (thanks @AllenInstitute, again) It's in the browser, online & free. No login or install required. 1/

What is the difference between excitatory and inhibitory neurons? Beyond the obvious difference of neurotransmitter effect on postsynaptic cell, another remarkable difference is the fact that excitatory neurons have lots of spines, while inhibitory neurons have less spines. 1/13

1/12 What if monkeys could have a language model too? 🐒💬 Our EMNLP 2025 paper introduces GmSLM — a Generative Marmoset Spoken Language Model. A pipeline for modeling, generating, and evaluating vocal behavior, trained on marmoset vocalizations. 👇

Congratulations!
New from the lab! Tirzah Kreisel found that astrocytic activation completely corrects memory in Alzheimer's mice, via neuronal activity and plasticity enhancement, and increased Aβ swallowing by astrocytes. biorxiv.org/cgi/content/shor… Let the war end and the hostages return 🎗️🤞🎗️

What makes human pyramidal neurons uniquely suited for complex information processing? How can human neurons’ distinct properties contribute to our advanced cognitive abilities?

🧠 Updated my open-source SWC Neuron Morphology Editor (runs directly in-browser!)—now with 3D views & custom segment colors (e.g., toggle axons). Demo uses @AllenInstitute MICrONS data. Can't wait to animate neurons for talks! #neuroscience #OpenScience

Human cortical pyramidal neurons are larger, exhibit more complex branching patterns, and feature distinctly nonlinear biophysical properties compared to rat cortical pyramidal neurons. Do these unique characteristics make human neurons more functionally complex? Would that enhance the capability of the human brain to perform complex computational tasks? Is this what makes us human? In our new preprint (see below) with @danielayoeli, @DavidBeniaguev, Christiaan de Kock, @mikilon, and @Segev_Lab we use deep learning to tackle these questions by comparing the complexity of neurons’ input-output (I/O) functions using our newly developed Functional Complexity Index (FCI) tool.

Congrats to my friend and colleague Guosong Hong for his stunning and original discovery, published today in Science, on clearing tissues *in living animals* with a common food dye! The dye is tartrazine, used in Doritos! science.org/doi/10.1126/scie…

I'm excited to share the publication of @GalAtlan 's final PhD project. Title is accurate for the take-home message, yet, there is a lot more to the paper, including the association of claustrum activity to individual variance in strategy. Check it out: nature.com/articles/s41467-0…

Mazal Tov, Haim!!! 🍾 @HSompolinsky And congratulation Larry!!! 🥂
Yesterday, we had the immense pleasure of celebrating neuroscience as we awarded Professors @HSompolinsky, Terrence Sejnowski, and Larry Abbott with #TheBrainPrize2024 medals for their pioneering contributions to the fields of computational and theoretical neuroscience. Thank you to all who attended, and a special thank you to HM The King of Denmark, the Danish Minister for Higher Education and Science @christinaegelun, @lundbeckfonden, and the chair of our selection committee, Richard Morris.

בגאווה ישראלית גדולה בירכתי היום את פרופסור חיים סומפולינסקי מהאוניברסיטה העברית בירושלים על זכייתו בפרס Lundbeck היוקרתי - הפרס החשוב ביותר בעולם בתחום חקר המוח. מדובר בהישג ישראלי פורץ דרך, שמשקף את מצוינות האקדמיה הישראלית במחקר ובכלל. אני סמוך ובטוח כי בעקבותיו יבואו עוד אותות ופרסים שיוקירו את תרומתם של ישראליות וישראלים לקהילה המדעית העולמית, ומקווה ופועל לכך שנדע להכיר תודה - כחברה וכמדינה - לענקי האקדמיה והמחקר שלנו.

Compare a typical brain with a typical modern day datacenter The datacenter mostly runs Artificial Intelligence applications, the brain mostly runs regular intelligence applications The datacenter consumes the power of a small town, the brain consumes the occasional banana

If you’re curious about whether and how you can use waveform and spiking information to predict the cell-type of an extracellularly recorded neuron, 1) yes you can, and 2) check out our preprint to find out! We cracked it for the major cell types of the cerebellum cortex. 1/5 🧵
Have you ever looked at traces from an extracellular recording and wondered what kind of neurons you are recording from? Five labs across three continents working with two species joined forces to solve this decades-old problem in systems neuroscience. 🧵
