Il sonno viene modellato dal patrimonio genetico (DNA) ereditato dai genitori e potrebbe anche avere una funzione molto più complessa di quella ipotizzata finora.
Lo rileva una ricerca condotta dal gruppo di Valter Tucci, dell'Istituto italiano di tecnologia di Genova, reso noto alla "Giornata mondiale del sonno".
Dallo studio è emerso che questa attività ha tantissimi aspetti misteriosi e che potrebbe giocare un ruolo importante nel regolare il metabolismo, la riparazione cellulare e anche l'equilibrio dei circuiti neuronali.
