Neonatal injury results in sex-dependent nociceptive hypersensitivity and social behavioral deficits during adolescence, without altering morphine response

Neonatal injury is associated with persistent changes in sensory function and altered nociceptive thresholds that give rise to aberrant pain sensitivity in later life. While these changes are well documented in adult rodents, little is known about the consequences of neonatal injury during adolescence. Since adolescence is a critical developmental period during which persistent pain conditions can arise, we examined the impact of neonatal injury on nociception, social behavior and response to morphine in adolescent Sprague Dawley rats.
