3 Midbrain- a small part of the brain above the pons that arouses the brain, integrates sensory information, and relays it upward
4 Forebrain- a part of the brain that covers the brain’s central core, responsible for sensory and motor control and the processing of thinking and languageThalamus- relays sensory information to and from the cortexHypothalamus- Controls functions like hunger, thirst, sexual behavior, and reactions to temperatureCerebral Cortex- Outer layer of forebrain, allows you to learn abstract informationCerebrum- Inner layer of forebrain, allows you to see, read, and is the site of thinking processesHippocampus- crucial to formation of memoriesAmygdala- controls violent emotions (rage, fear)Pituitary Gland- secretes hormones (growth gland)Limbic System- Controls emotions and motivations (Thalamus, Hypothalamus, Amygdala, Hippocampus)
5 LOBESLobes- the different regions into which the cerebral cortex is dividedOccipital Lobe- VisionParietal Lobe- Body Sensations (Skin/Muscles)Primary Somatosensory Cortex (Touch Sensors)Primary Motor Cortex (Fine Movement Control)Frontal Lobe- Short-Term Memory/Planning Of MovementsTemporal Lobe- Hearing
