Prenatal solid tumors can disrupt fetal brain development, altering cortical folding. Tumor growth and location significantly impact brain convolution, potentially leading to disorders.
Area of Science:
- Neuroscience
- Developmental Biology
- Biophysics
Background:
- Cortical folding (gyrification) is crucial for mammalian brain function.
- Prenatal solid tumors can interfere with normal brain development.
- Understanding tumor impact on brain structure is vital for predicting developmental disorders.
Purpose of the Study:
- To investigate the effects of growing solid tumors on fetal brain cortical folding.
- To model the developmental mechanism of cortical convolution under tumor influence.
- To analyze how tumor characteristics affect brain structure.
Main Methods:
- Theoretical analysis of deformation and stress in a double-layered brain model.
- Non-linear finite element simulations for crease formation analysis.
- Parametric studies on tumor size, location, and growth speed.
Main Results:
- Tumor size, location, and growth speed significantly influence cortical folding patterns.
- A critical tumor distance from the cortex/core interface maximizes its effect.
- Growing tumors decrease the gyrification index, while stiffness has minimal impact.
Conclusions:
- Growing solid tumors disrupt fetal brain convolution.
- Tumor characteristics critically determine the extent of cortical folding alteration.
- This research provides insights into tumor-induced brain developmental abnormalities.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
