Abstract

A large number of hyposerotonergic genetic models have been generated over the past few years. Serotonin (5‐HT) depletion has been obtained via targeting of genes involved in 5‐HT synthesis (Tph1 and Tph2), specification and determination of the 5‐HT phenotype during development (GATA3, Pet1, and Lmx1b), and 5‐HT storage or clearance (Vmat2 and SERT). Here we review these various models from a developmental perspective, beginning with a description of the sources of 5‐HT during development. We then summarize the neurological and behavioral alterations that have been observed in the genetic hyposerotonergic models. Although these models appear to have normal brain development and do not exhibit any gross morphological defects, problems in somatic growth and physiological functions have been observed. Abnormal adult behavior is also seen, although whether it results from depletion of 5‐HT during development or functional 5‐HT deficiencies in adult life remains unclear. Evidence from these hyposerotonergic models suggests that the developing brain may not need 5‐HT for the establishment of general organization and structure. However, central 5‐HT appears to be necessary for postnatal body growth, maturation of respiratory and vegetative control, and possibly for the development of normal adult behavior.

  • Serotonin exerts a significant trophic and modulatory function in neurodevelopmental processes such as proliferation, migration, and differentiation in cortical areas, including the PFC.

    “It has become widely accepted that serotonin exerts a significant trophic and modulatory function in neurodevelopmental processes such as proliferation, migration and differentiation in cortical areas, including the PFC [119, 123, 125–129].”

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.
