Neurotransmitters

For AP Pysch

QuestionAnswer
Dopamine Influences motivation and pleasure (brain’s reward system) and movements, Too much of this can lead to schizophrenia, Too little of this can lead to Parkinson's (loss of muscle control)
Serotonin Helps with feelings of well-being and satisfaction, mood, consciousness (sleep and awareness), and hunger, Low levels of this are linked with depression
Norepinephrine Controls stress responses, adrenaline, fight/flight arousal (slightly affects blood vessels more)
Epinephrine (aka adrenaline) controls fear or stress responses, increases heart rate & heart contractions, restricting blood flow and raising blood pressure (slightly affects the heart more)
Acetylcholine Controls memory formation, muscle control and learning, low levels of this can lead to Alzheimer's
GABA Slows down the brain by producing a calming effect, reduce anxiety. Low levels can cause muscle fatigue and seizures
Glutamate Controls cognitive, motor, and sensory functions (also learning and memory)
Endorphins Acts as a natural pain reliever
Adenosine Influences the release of other neurotransmitters, usually suppresses them related to energy transfer (sleep)
Anandamide Regulate communication between other neurons related to immune function, learning and memory, metabolism, stress, motor behavior, pain perception (basically everything) main goal is eating motivation
Agonists Increases the effects of a neurotransmitter
Antagonists Blocks a neurotransmitter from functioning
Somatic Includes the muscular and skeletal systems and it controls voluntary movements, can cause muscle paralysis under agonists & antagonists
Autonomic Includes sympathetic and parasympathetic nervous systems and controls involuntary body movements, under the influence of antagonists it blocks all responses and it triggers them under agonists
Sympathetic Nervous System Stress response system, initiates the body’s flight/flight/freeze response, under antagonists the response does not trigger, under agonists, it does trigger
Parasympathic Nervous System Conserves energy and stimulates rest in the body, under antagonists the response does not trigger, under agonists, it does trigger
