A hallmark of anorexia nervosa is the willful seeking and maintenance of a starvation state, potentially as a means to cope with stressful life experiences or trauma. Hakan Kucukdereli and Mark Andermann share their research on how they designed a virtual reality paradigm to study this phenomenon in mice.

Researchers from Mass. General Hospital, University College London, and the University of the Republic in Uruguay found a two-way association between anorexia-related genes and those associated with the morning chronotype (waking early/going to bed early). This contrasts with disorders such as depression, binge eating disorder, and schizophrenia, which are associated with an evening chronotype.
