Interaction with pups enhances dopamine release in the ventral striatum of maternal rats: A microdialysis study

Hansen, S., Bergvall, Å.H., Nyiredi, S.·1993·Pharmacology Biochemistry and Behavior

Abstract

A growing body of evidence suggests that an interference with dopamine (DA) transmission disrupts maternal behavior in the rat. The present brain microdialysis study was therefore conducted to investigate whether infants can modulate ventral striatal DA release in mother rats. There was a significant rise in the extracellular concentrations DA, 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5-HIAA) in the ventral striatum when mothers were reunited with their litters following separation overnight. Nursing was the predominant behavior during this phase of the experiment. More active behaviors were elicited by soiling pups with flowerpot earth, and this was accompanied by further increases in DA, DOPAC, HVA, and 5-HIAA. It is suggested that pup-induced stimulation of ventral striatal DA release facilitates parental responses such as pup retrieval.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Dopamine is released naturally in the nucleus accumbens of maternal rats during interactions with pups.

    “DA is released naturally in the NAC of maternal rats during interactions with pups (Hansen et al 1993).”
  • Applying dopaminergic antagonists or dopaminergic neurotoxins to the nucleus accumbens interrupts mother-pup interactions.

    “whereas applying dopaminergic antagonists or dopaminergic neurotoxins to the region interrupts such interactions (Hansen et al., 1993, Hansen et al., 1991a, Keer and Stern, 1999, Numan et al., 2005).”

  • Dopamine is released within the nucleus accumbens when a mother rat grooms or licks her offspring or after being reunited with her offspring after forced separation.

    “Dopamine is released within the nucleus accumbens when a mother rat grooms or licks her offspring or after being reunited with her offspring after forced separation (Champagne et al., 2004, Hansen et al., 1993).”

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.
