Developmental effects of selective breeding for an infantile trait: the rat pup ultrasonic isolation call.

Developmental psychobiology - 1 Dec 2001

Hofer M A, Shair H N, Masmela J R, Brunelli S A

Abstract excerpt

This article describes how continued selection for divergent levels of the 10-day-old infant rat's ultrasonic vocal (USV) response to isolation affects the time course of development of that and other possible co-selected traits from 3 to 21 days postnatally. Since selective breeding for an infantile trait has not been reported before, we collected from colleagues a number of predicted outcomes that reflect the...
