Overview

Experimental elevation of maternal corticosterone alters offspring's anxiety responses and predictability.

Key Points

  • Elevated maternal corticosterone leads to offspring that are less anxious and more predictable.
  • Offspring's behavioural predictability was assessed through 16 trials in an open-field test.
  • Experimental manipulation of maternal stress reveals insights into behavioural variation among individuals.
  • These findings highlight a mechanism by which prenatal stress affects behavioural phenotype diversity.
