english: It works like this: You take a brain, or parts of that brain, and you dissolve it in detergent, which destroys the cell membranes but keeps the cell nuclei intact, so you end up with a suspension of free nuclei that looks like this, like a clear soup.
non_english: Tako deluje: Vzamemo možgane ali dele možganov in jih raztopimo v detergentu, ki uniči celično membrano, jedro pa pusti nedotaknjeno, tako da dobimo suspenzijo prostih jeder, ki izgleda takole - kot bistra juha.
