O ensaio cometa é uma forma eficiente de detectar quebras simples e de fita dupla, incluindo álcali-lábeis sites e DNA-DNA/DNA-protein ligações cruzadas no DNA em todas as células, incluindo neurônios do hipocampo. O método tira partido da migração diferencial de DNA num campo eléctrico devido a diferenças na quantidade de danos no DNA.
