Implication

Preclinical study reveals distinct and sex-dependent neurobiological outcomes of early life adversity in adult mice, highlighting the need for sex-specific psychiatric approaches.

Key Points

To determine how developmental stress permanently alters adult neurobiology and behavior across sexes to understand the mechanisms underlying sex differences in psychiatric risk.
Evaluated adult male and female mice exposed to early life developmental stress using multi-level neurobiological and behavioral analyses.
Integrated whole-brain c-Fos activity mapping, manganese-enhanced MRI, and transcriptomic profiling with advanced behavioral phenotyping.
Developmental stress induced distinct and often opposite neurobiological and behavioral alterations between adult male and female mice.
Multi-scale profiling demonstrated widespread, sex-specific differences across neural activation patterns, brain structural networks, and gene transcription.
