Buprenorphine, the active ingredient in both Suboxone and Subutex is less likely to cause addiction, and has a calmer withdrawal period. More clinical studies have been done on the effects of methadone during pregnancy than the effects of buprenorphine during pregnancy.
You won't believe these 10 facts about people. Gray matter or grey matter is a type of neural tissue which is found in the brain and spinal cord. It is named after its distinctive brownish-gray color, in contrast with white matter, another type of neural tissue which appears white because it is coated in myelin sheathes.
White matter is located at the base of the brain between the cerebellum and the brainstem. It is made of long nerve fibers called axons. The axons are insulated by myelin, sheaths of fat that give the region the white color for which it is named. The myelin helps speed up the transmission of signals along the axons.
