The illusion of illusions
One of the oldest myths in human history is that the Parthenon was cleverly built with curves so that it looks straight, to correct some visual illusions

This is a very nice paper that answers a simple question that we have been pondering for years: Can you represent the dynamics in regions connected by pipes by a much simpler network? Very important for toxic proteins in the brain.
The answer is yes, but you have to do it properly.

The Deceived Brain: Coding and Illusion | Gresham College
We perceive the world through the processing of information given by our senses. Sometimes, this processing is faulty, leading to illusions: shapes or sounds that we perceive differently from their physical reality. These illusions have delighted children and scientists alike for centuries. This lecture reveals how simple geometric illusions can be modelled mathematically, based on our understanding of how visual signals are coded and decoded by the brain, leading to a better understanding of how we process information.
