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.

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
