  • Whether and how hypothalamic neurons can lose or change their identity in adulthood has remained elusive. Here, the authors show that mature pro-opiomelanocortin (Pomc) neurons contain invisible ‘Ghost’ subsets with atypical identities that are recruited in response to obesogenic stimuli.

This Comment raises awareness of key conceptual and technical aspects that can increase the quality and reproducibility of this type of data.

  • Fabien Pifferi et al. report survival and age-related brain atrophy data in grey mouse lemurs fed either a normal diet or a diet restricted in calories by 30%. They find that caloric restriction extended life span by 50% and decelerated brain white matter atrophy, but accelerated the loss of grey matter, in most of the cerebrum.
