This book is about memory and its myths. Rodrigo Quiroga is a recognized Argentinian neuroscientist known to have discovered the “Jennifer Aniston” neurons, named concept cells. These are neurons that “fire” when a person sees an object that represents a concept. By showing images of famous people, like Jennifer Aniston or Luke Skywalker, they found that some neurons specifically fire when those images are presented to the person (for a review, you can read reference 1).
Rodrigo smoothly writes about the misconception regarding our capacity to retain rich details from our memories. The reality is that the brain doesn’t and can’t do this! Our brain remembers the context instead of the details because we don’t have enough neurons to account for this.
