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.
Patients with subependymal heterotopias had a significantly higher prevalence of normal development than patients in the other two groups (P = .02). When all patients with gray matter heterotopias were considered, patients with thick heterotopias and those with overlying cortical gyral anomalies, which correlated with one another, had a significantly higher prevalence of developmental delay (P = .002).
