Lifespan Alterations of Basal Dendritic Trees of Pyramidal Neurons in the Human Prefrontal Cortex: A Layer-Specific Pattern

Petanjek, Z., Judas, M., Kostovic, I., Uylings, H. B. M.·2008·Cerebral Cortex

Abstract

The postnatal development and lifespan alterations in basal dendrites of large layer IIIC and layer V pyramidal neurons were quantitatively studied. Both classes of neurons were characterized by rapid dendritic growth during the first postnatal months. At birth, layer V pyramidal neurons had larger and more complex dendritic trees than those of layer IIIC; however, at 1 postnatal month both classes of neurons displayed a similar extent of dendritic outgrowth. In addition, after a more than year-long "dormant" period of only fine dendritic rearrangement, layer IIIC pyramidal neurons displayed a second period of dendritic growth, starting at the end of the second year and continuing in the third year. During that period, the dendritic tree of layer IIIC pyramidal neurons became more extensive than that of layer V pyramidal neurons. Thus, layer IIIC pyramidal neurons appear to show a biphasic pattern of postnatal dendritic development. Furthermore, the childhood period was characterized by transient increase in size of pyramidal cell somata, which was more pronounced for neurons in layer IIIC. These structural changes occurred during both the period of rapid cognitive development in preschool children and the period of protracted cognitive maturation during the childhood, puberty, and adolescence.

  • At birth, layer V neurons have more complex basal dendritic trees than layer IIIC neurons; layer V neurons reach maximum complexity at 16 to 30 months, before layer IIIC neurons.

  • Layer-specific dendritic development in layer IIIC pyramidal neurons in the human prefrontal cortex (Broca region) is coincident with the preoperational stage of cognitive development.

    “Recent studies have also shown layer-specific dendritic development in layer IIIC pyramidal neurons in the human prefrontal cortex (specifically in Broca region) which is coincident with preoperational stage of cognitive development (Judas and Cepanec 2007;Petanjek et al. 2008).”

  • A similar pattern is observed in certain subtypes of dendrite in the human prefrontal cortex, which decline in arborization starting between ~10-15 years old, though it is unknown if there is a sex difference.

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.
