Study Notes
Drug Tolerance
- Repeated use of agonist drugs causes tolerance.
- Agonists mimic natural neurotransmitters, triggering or enhancing normal cellular responses.
- Nerve impulses are transmitted due to agonist stimulation of specific receptors.
- The nervous system compensates for overstimulation.
- This compensation involves a decrease in receptor number and sensitivity.
- This desensitization leads to drug tolerance, requiring higher drug doses for the same effect.
Drug Addiction
- Repeated use of antagonist drugs leads to addiction.
- Antagonists block receptor sites, preventing natural neurotransmitter action.
- The nervous system responds by increasing receptor number and sensitivity.
- This sensitization leads to addiction, characterized by craving for more of the drug.
Neurotransmission and Recreational Drugs
- Many recreational drugs impact neurotransmission at synapses, influencing mood, cognition, perception, and behavior.
- These drugs often affect the brain's reward pathway.
- Drugs can mimic or interact with neurotransmitters in various ways, including stimulating release, mimicking action, inhibiting reuptake, blocking activity, or inhibiting breakdown.
