Title: Looking into the mind of the mother : pup exposure and reactivation of maternal circuits
Author: Nokunas, Tricia Lauren
Abstract: The female rat, among other species, undergoes a fundamental brain re-modeling as a consequence of experiencing the normal and natural events of pregnancy and offspring stimulation. Compelling data show that maternal experiences produce neurobiological modifications in the female leading to specific maternal behaviors, affective states, and the basic underlying female neurobiology necessary to raise viable offspring. This study aims to evaluate the number, quality and selective activation of neurons that develop during the maternal experience. The study showed a trend toward supporting the hypothesis that a "maternal-circuit" is formed through the proliferation of neurons during late-motherhood and lactation, and is selectively reactivated by mothers exposed to foster pups.
