Motivational systems and the neural circuitry of maternal behavior in the rat

Abstract

Jay Rosenblatt's approach‐avoidance model of maternal behavior proposes that maternal behavior occurs when the tendency to approach infant stimuli is greater than the tendency to avoid such stimuli. Our research program has uncovered neural circuits which conform to such a model. We present evidence that the medial preoptic area (MPOA: located in the rostral hypothalamus) may regulate maternal responsiveness by depressing antagonistic neural systems which promote withdrawal responses while also activating appetitive neural systems which increase the attractiveness of infant‐related stimuli. These MPOA circuits are activated by the hormonal events of late pregnancy. Preoptic efferents may suppress a central aversion system which includes an amygdala to anterior hypothalamic circuit. Preoptic efferents are also shown to interact with components of the mesolimbic dopamine (DA) system to regulate proactive voluntary maternal responses. We make a distinction between specific (MPOA neurons) and nonspecific motivational systems (mesolimbic DA system) in the regulation of maternal responsiveness. © 2006 Wiley Periodicals, Inc.

  • There is well-documented evidence for anatomical circuitry underlying specific actions in mammals, such as vocalizations, maternal behavior, freezing, startle, attack, and appetitive behavior.

    “There is well-documented evidence for the anatomical circuitry underlying specific actions such as vocalizations (Jürgens 2009), maternal behavior (e.g., pup retrieval, grooming, nest building, and nursing; Numan 2007), freezing (Fanselow & Poulos 2005), startle (Davis et al. 2008; Lang et al. 2000), attack (Blanchard & Blanchard 2003) and appetitive behavior (Berridge & Kringelbach 2008; Shultz 2”

  • One role of the mesolimbic dopamine pathway and accumbal dopamine is to generate the powerful motivational states that produce maternal behaviors.

    “This suggests that, similar to drugs of abuse, one role of the mesolimbic DA pathway and of accumbal DA in particular is to generate the powerful motivational states that produce such dramatic maternal behaviors (reviewed in Numan 2007; for a comprehensive treatment of the subject, see Numan and Insel 2003).”
  • In rodents, changes in the neural structure and function during the early postpartum period have been observed consistently to support maternal motivation and to enhance processing of sensory information that is specialized to detect and respond to infants' calls.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
