It turns out, you can get the building blocks, monomers, as they're called, and if you let them go into the brain and then trigger the chemical reactions, you can get them to form those long chains, right there inside the brain tissue.
Podemos obter os compoñentes esenciais, chamados monómeros, e deixalos entrar no cerebro, e logo, desencadear as reaccións químicas, para chegar a formar esas longas cadeas, alí, no interior do tecido cerebral.
