استعداد ژنتیکی به چاقی بر صفات رفتاری شامل پاداش غذا و رفتار اضطراب مانند در موش صحرایی تاثیر می گذارد

Together our data demonstrate that rat strains that differ in their genetic predisposition to develop obesity also differ in their performance in behavioural tests linked to anxiety, exploration, and reward and that these differences are independent of body weight. We conclude that genetic variations which determine body weight and the aforementioned behaviours co-exist but that future studies are required to identify whether (and which) common genes are involved.
