Abstract

Tangential migration from the basal telencephalon to the cortex is a highly directional process, yet the mechanisms involved are poorly understood. Here we show that the basal telencephalon contains a repulsive activity for tangentially migrating cells, whereas the cerebral cortex contains an attractive activity. In vitro experiments demonstrate that the repulsive activity found in the basal telencephalon is maintained in mice deficient in both Slit1 and Slit2, suggesting that factors other than these are responsible for this activity. Correspondingly, in vivo analysis demonstrates that interneurons migrate to the cortex in the absence of Slit1 and Slit2, or even in mice simultaneously lacking Slit1, Slit2 and netrin 1. Nevertheless, loss of Slit2 and, even more so, Slit1 and Slit2 results in defects in the position of other specific neuronal populations within the basal telencephalon, such as the cholinergic neurons of the basal magnocellular complex. These results demonstrate that whereas Slit1 and Slit2 are not necessary for tangential migration of interneurons to the cortex, these proteins regulate neuronal migration within the basal telencephalon by controlling cell positioning close to the midline.

  • Interneurons move toward the cortex along a gradient of increasing permissivity produced by chemoattractive cues in the developing LGE and pallium.

    “Interneurons migrate toward the cortex following a gradient of increasing permissivity generated by chemoattractive cues produced in the developing LGE and pallium (Marín et al., 2003; Wichterle et al., 2003).”

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.
