[Brain warts]

K D Schulze, H Braak

    Summary
    This summary is machine-generated.

    Warty extraversions, or cortical malformations, are found in 26% of studied brains, primarily in the frontal lobe's lower frontal gyrus. These malformations show variations in cortical layers but no increased nerve cell count.

    Area of Science:

    • Neuroscience
    • Neuroanatomy
    • Pathology

    Context:

    • Cortical malformations represent deviations from typical brain development.
    • Understanding their prevalence and structural characteristics is crucial for neurological research.

    Purpose:

    • To investigate the prevalence and morphological characteristics of warty extraversions in the human brain.
    • To analyze the cytoarchitecture and cellular composition of these cortical anomalies.

    Summary:

    • Warty extraversions were identified in 26% of 108 studied brains, predominantly located on the lower frontal gyrus within the frontal lobe.
    • These malformations exhibit variations in cortical layers, including ectopic nerve cells in layer I and altered cellular arrangements in deeper layers.
    • Despite structural changes, no numerical increase in nerve cells was observed within the malformations compared to normal isocortex.

    Impact:

    • Provides detailed anatomical and cellular insights into a specific type of cortical malformation.
    • Contributes to the understanding of brain development variations and potential neurological implications.
    • Offers a baseline for future research on the functional consequences of such brain anomalies.
