I could take any of you, pop you in the scanner, and find each of those regions in your brain, and it would look a lot like my brain, although the regions would be slightly different in their exact location and in their size.
Poderia pegar qualquer um, colocar num scanner, e encontrar cada uma  de suas regiões cerebrais, e se pareceria muito com meu cérebro, apesar das regiões  serem pouco diferentes no tamanho e no local exato.
