Neurotransmitters
For AP Pysch
| Question | Answer |
|---|---|
| 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 |
