Development and Evolution of the Human Neocortex

Open access

Abstract

The size and surface area of the mammalian brain are thought to be critical determinants of intellectual ability. Recent studies show that development of the gyrated human neocortex involves a lineage of neural stem and transit-amplifying cells that forms the outer subventricular zone (OSVZ), a proliferative region outside the ventricular epithelium. We discuss how proliferation of cells within the OSVZ expands the neocortex by increasing neuron number and modifying the trajectory of migrating neurons. Relating these features to other mammalian species and known molecular regulators of the mouse neocortex suggests how this developmental process could have emerged in evolution.

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

  • The underlying biological mechanisms that lead to altered formation of the cortex in individuals with Down syndrome may not be reflected in existing mouse models owing to differences in neurodevelopment across species.

    “Moreover, the underlying biological mechanisms that lead to altered formation of the cortex in individuals with DS may not be reflected in the mouse models that do exist, owing to differences in neurodevelopment across species23–27.”

    From Consequences of trisomy 21 for brain development in Down syndrome (2024) · cites this paper as [26]

    The Introduction says that species differences limit how well rodent neocortices can model human cortical development. It does not address Down syndrome or test whether existing Down syndrome mouse models reflect the mechanisms of altered cortical formation. (LLM, conf=0.84)

  • The expansion of the telencephalon in parrots and songbirds is associated with delayed and protracted neurogenesis, an expanded subventricular zone, and delayed neuronal maturation.

    “First, just like the expansion of neocortex in primates (52), the expansion of the telencephalon in parrots and songbirds is associated with delayed and protracted neurogenesis, an expanded subventricular zone, and delayed neuronal maturation (53–55).”

    From Birds have primate-like numbers of neurons in the forebrain (2016) · cites this paper as [52]

  • oRGs are present in large numbers in gyrencephalic primates and are considered pivotal to the evolutionary increase in human cortex size and complexity.

    “oRGs are present in large numbers in gyrencephalic primates22,23,40–44 and are considered pivotal to the evolutionary increase in human cortex size and complexity45,46.”
  • Cortical surface area and thickness are controlled by mechanisms involved in RGC and IPC proliferation and differentiation decisions.

    “Cortical surface area and thickness are controlled by the mechanisms involved in RGC and IPC proliferation and differentiation decisions [99, 100].”
  • The subdivision of subventricular zone in primates and other large-brained mammals establishes the expanded proliferative zone in outer subventricular zone that generates a greater number of neurons and glial cells.

    “One such example is the subdivision of SVZ in primates, and in other mammals with a large brain (Fietz et al., 2010; Hansen et al., 2010; Lui et al., 2011; Smart et al., 2002) to establish the expanded proliferative zone in the oSVZ that generates a greater number of neurons and glial cells.”

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.
