Return to overview

I would like to better understand the informations (validations, etc.) on the box that appears when I ask “return to overview” and what represents the part of the neuron drawn in white.

Grazie

When the overview is on your screen, and you click on your name in the leaderboard (the one with your points by day, week, and month) the parts of the cell that you personally have mapped show up in a contrasting color. You can also click on another name to see what the other player has mapped on that cell. The information that shows up may not have the latest data. I think it may be about a week old.
