Building a tiny "DNA brain"

An animated explanation of recent research building artificial neural networks out of interacting DNA molecules. Part I introduces the motivation, the mathematical model of a neuron, and the design of a DNA-based neural network that is capable of recalling a memory when presented with partial information. Part II introduces how to make such a DNA-based neural network in the laboratory, how it remembers four scientists and identifies one of them given an incomplete answer to a set of yes-or-no questions, and how this work could be related to the evolutionary history of intelligence.
