Study Notes
Neurotransmitters
- Neurons that release a certain neurotransmitter are named after it, e.g., cholinergic neurons release acetylcholine (ACH).
- Neurons can be classified as motor, sensory, or autonomic, depending on their function.
Acetylcholine (ACH)
- ACH is a neurotransmitter involved in controlling muscle contractions, memory, and sensory perception.
- It is released by motor neurons and is responsible for controlling muscles and glands.
- High concentrations of ACH are found in the spinal cord and hippocampus.
Norepinephrine
- Norepinephrine is a neurotransmitter involved in controlling the autonomic nervous system, sleep, and emotions.
- Neurons that release norepinephrine are referred to as noradrenergic neurons.
Neurotransmitter Function
- Neurotransmitters can be either excitatory (stimulating) or inhibitory (calming) depending on the receptors they bind to.
- The response to a neurotransmitter is determined by the receptors it binds to, which can be either excitatory or inhibitory.
Agonists and Antagonists
- Agonists mimic the action of a neurotransmitter, increasing its effect, e.g., cocaine is a dopamine agonist.
- Antagonists block the action of a neurotransmitter, reducing its effect, e.g., curare is an acetylcholine antagonist.
Other Neurotransmitters
- Serotonin is involved in controlling sensory perception, temperature regulation, sleep, and emotions.
- Dopamine is involved in reward, motivation, and pleasure, and is linked to addiction and schizophrenia.
