So I was really excited when my mice developed this compulsive behavior, where they were rubbing their faces and they couldn't seem to stop, even when they were wounding themselves.
Úgyhogy nagy izgalomba jöttem, mikor a kísérleti egereim végre kényszeres cselekvést mutattak: dörzsölték az arcukat, és akkor sem bírták abbahagyni, amikor már kisebesedtek.
