Oh ok, didn't know that's a way of mapping neural activity. Pretty cool~~

(I still don't understand it, but that's ok)

How do they quantify this similarity other than "measuring neural responses to movie clips"? What does measure mean exactly?

I assumed it to be the euclidian distance between the centre of neural activation measured. That could be entirely wrong tho.
