Silicone rubber is a silicon polymer with rubberized qualities. It was first produced under the chemical name of polydimethlysiloxane. Silicone rubber is heat resistant so can be used to make cookware including oven mitts, tongs, pot holders and pan handles.ilicone, the product, may be a liquid lubricant, a semi-solid adhesive or a rubber-like plastic polymer.

Gray matter heterotopia is a neurological disorder that is characterized by the gray matter in the brain being located in the wrong part of the brain. It is associated with epilepsy and can affect higher brain functions and motor skills. Seizures are generally resistant to medication.
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)
