Subcontractor Agreement Basics. Whether you're a subcontractor or just hiring one, a subcontractor agreement helps protect both your interests. As an agreement between a general contractor and a subcontractor, it describes the services and materials provided by the subcontractor, price of the work, and warranties of the parties. Other important clauses include insurance, default, change orders, and indemnification.
A subcortical heterotopia may appear to have mass effect on the adjacent ventricle, so it is important to use imaging clues, such as lack of enhancement, isointense signal to gray matter, lack of associated edema, and diminished volume in the affected region of brain, to differentiate this entity from tumor.
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)
