Document Summary
Consists of many myelinated structures which contributes a lot of fat to the brain. Despite its size, it uses many resources and generates a lot of power. It is continuously developing until the age of 25. The frontal lobe develops last - this is where complex processes take place. Sits within the cranial cavity and is protected by the skull. The cerebrum makes about 80% of the size of the brain. The ventricular system contains fluid that nourishes the brain and connects with space outside of the brain. There is buoyancy so the brain is consistently floating around. When electrical brain scans are done, we sense the cerebral cortex. There are highways" that occur throughout the cerebral cortex. Deep gray matter structures are called the basal ganglia, which have a variety of functions (ex. There are four lobes on each side. Higher order processing such as cognition and personality occurs here. Everything that you sense will end up here.
