Heterotopia are nodules or clumps of misplaced neurons that did not move to the correct location in the brain during earlydevelopment. Heterotopia are common malformations of cortical development.
What is Heterotopia? Heterotopia occurs when nerve cells (neurons) do not migrate properly during the early development of the fetal brain. Heterotopia means out of place. In normal brain development, neurons form in the periventricular region, located around fluid-filled cavities (ventricles) near the center of the brain. The neurons then migrate outward to form the exterior of the brain (cerebral cortex) in six onion-like layers. Types-Periventricular Heterotopia (PH)
