 ## ORGANISM
 
-Qui comprendiamo l'organismo. Qui dentro, oltre all'espansione degli organi, ci va anche un organo tipo Ipotalamo, che gestisce l'alternanza DAY/NIGHT.

 Qui comprendiamo Hypothalamus. E' l'organo che si occupa di far "dormire" l'organismo, in maniera da rendere possibile i comportamenti che associamo alla modifica di forma organimisca, compresa quella neuronale.
