Neuroscience exploration - Logarithmic nature of the brain 💡

Shortform link: https://shortform.com/artem ===== My name is Artem, I'm a neuroscience PhD student at Harvard University. 🌎 Website and Social links: https://kirsanov.ai/ 📥 "Receptive Field" neuro-newsletter: https://artemkirsanov.substack.com/ ✨ Support me on Patreon to get access to Discord community: https://patreon.com/artemkirsanov ===== In this video we will talk about the fundamental role of lognormal distribution in neuroscience. First, we will derive it through Central Limit Theorem, and then explore how it support brain operations on many scales - from cells to perception. 🕒 OUTLINE: 00:00 Introduction 01:15 What is Normal distribution 03:03 Central Limit Theorem 04:23 Normality in biology 05:46 Derivation of lognormal distribution 10:20 Division of labour in the brain 12:20 Generalizer and specialist neurons 13:37 How lognormality arises 15:19 Conclusion 16:00 Shortform: sponsor message 16:54 Outro 📚 FURTHER READING & REFERENCES: 1.
