• The Brain Stem controls breathing and heartrate
• The Medulla controls breathing, heartrate, and blood pressure
• The Regular Activating system controls alertness, consciousness, and arousal
• The Brain's reward center processes stimuli and associates them with positive outcomes
• The Cerebellum controls balance and posture
• The Cerebral Cortex is made up of 4 lobes and controls complex thinking
• The Limbic system manages emotions, hunger, and motivation.
• The Thalamus controls all senses except for smell and directs sensory information
• The Hypothalamus controls hunger, thirst, sleep, and temperature
• The Pituitary Gland controls growth hormones
• The Hippocampus controls memory formation
• The Amygdala controls strong emotions
• The Corpus Callosum us a bundle of nerve fibers that connects the left and right lobes of the brain
• Association Areas integrate information from other parts of the brain for complex thinking.
• The Prefrontal cortex is the last part of the brain to fully develop and controls executive functioning
• Broca's Area produces speech
• Wernicke's area controls speech comprehension
• The Occipital lobe is in the back of the brain and contains the visual cortex
• The Temporal lobe is on the bottom of the brain and contains the auditory cortex
• The Frontal lobe contains the motor cortex
• The Parietal lobe is on the top of the brain and contains the somato sensory cortex
• aphasia: inability (or impaired ability) to understand or produce speech due to brain damage.
• lesioning means to destroy
• The Peripheral Nervous system is all nervous tissue outside of the brain and spinal cord
• The somatic nervous system controls voluntary movement
• The autonomic nervous system controls automatic movement
• The sympathetic nervous system is focused on short term survival during stress
