THE BRAIN 3 Sections of the Brain: Hindbrain: Medulla, Pons, Cerebellum Midbrain: Reticular Activating System Forebrain: Thalamus, Hypothalamus, Limbic System, Cerebrum
THE BRAIN Reticular Activating System: attention, sleep, arousal Limbic System: if damaged, people can recall old memories, but cannot create new memories Cerebrum: 70% of total weight
