Abstract

Serotonin (5-HT) exerts prominent morphogenetic roles during development. For example, somatosensory cortical barrel formation is altered in mouse models characterized by excessive extracellular 5-HT, suggesting that 5-HT affects development of thalamic afferents and/or neocortical target regions. The present study assessed 5-HT effects in primary cultures of fetal ventroposterior thalamic (VPT) neurons. 5-HT produces concentration-dependent trophic effects, with impressive 59% and 106% peak increases in total neurite length and number of branching points, respectively, at a dose of 30 microM 5-HT. The exposure of VPT neurons to specific 5-HT receptor agonists 8-OH-DPAT (5-HT(1A)), CGS-12066A (5-HT(1B)), DOI (5-HT(2A/2C)), and m-CPBG (5-HT(3)), enhances primary neurite length and number of branching points with rank-order potency 5-HT(1B) > 5-HT(2A/2C) = 5-HT(3) > 5-HT(1A) = vehicle. Trophic 5-HT effects on embryonic VPT neurons are thus much more prominent than previously reported, and can be mediated by multiple 5-HT receptor subtypes.

  • DOI increases dendritic growth in cultured cortical neurons.

    “DOI, one of the more readily accessible psychedelics to researchers, has been shown to increase dendritic growth (Persico et al., 2006;Ohtani et al., 2014;Ly, Greb et al., 2018;Ly et al., 2021), synaptic puncta, spine density (Yoshida et al., 2011;Ly et al., 2018), and spine size (Jones et al., 2009) in cultured cortical neurons.”

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.
