Cerebral cortex folding, or gyrification, is key to brain evolution, enabling larger, more complex brains. This overview details recent advances in understanding the developmental processes that shape brain structure.
Area of Science:
- Developmental neuroscience
- Evolutionary biology
- Neuroanatomy
Background:
- Cortical folding is crucial for mammalian brain evolution, increasing size and complexity.
- This process optimizes brain organization, wiring, and cranial fitting during development.
- It involves intricate cellular, mechanical, and genetic regulatory mechanisms.
Purpose of the Study:
- To provide an updated overview of recent advances in cortical gyrification.
- To synthesize current knowledge on the developmental mechanisms regulating brain folding.
Main Methods:
- Review of recent scientific literature on cortical development.
- Analysis of cellular and mechanical processes involved in gyrification.
- Examination of genetic regulatory programs.
Main Results:
- Significant progress has been made in understanding the cellular and molecular drivers of cortical folding.
- Key insights into the roles of neural stem progenitor cells and neuronal migration.
- Advances in deciphering the genetic control of gyrification patterns.
Conclusions:
- Cortical folding is a complex, multi-faceted process essential for brain evolution.
- Recent research has significantly enhanced our understanding of its developmental regulation.
- Further investigation into these mechanisms can inform our knowledge of brain development and evolution.

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...
Amyloid Fibrils
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Mechanism of Ciliary Motion
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...
