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.

Emotional eating is known to be a contributing factor to overeating and can potentially lead to obesity or disordered eating. Laura Holsen shares new research showing how differential responsivity to stress may increase the risk of developing maladaptive eating behavior.
