Introduction to Neuropsychopharmacology Flashcards
Drug definition
An administered substance that affects physiological functioning
Psychopharmacology studies drugs that affect our
Mood
Perception
Cognition
Behaviors
Neuropsychopharmacology is important because
Drug abuse and addiction are prevalent
Provides insight into human behavior
Provides insight into therapeutic drug development
Endogenous Substance
Substance produced inside an organism.
Exogenous Substance
Comes from outside of the body
Dose definition
Drug amount/body weight. Amount of drug per body weight
ED50
Effect dose for 50% of people. AKA The dose in which 50% of people experience effects
Potency
How much of the drug it takes to achieve an effect
TD50
Toxic dose for 50% of people. AKA TD50 = the dose at which 50% of the people have toxic effects.
Therapeutic Index
TD50 / ED50
Higher = more therapeutic, less toxic
Certain safety index
TD1 / ED99
Higher = safer, more certainty of safety
LD50
Lethal dose for 50% of people. AKA The dose at which 50% of people die
Problems of intuition as a way to acquire knowledge
Illusory correlation
Correlation =/= causation. Third variable problem
Susceptible to bias (Ex: eugenics, bigotry)
Overconfidence - Dunning-kruger effect
Observation as a way to acquire knowledge
Critical to good science: empiricism
Works best with objective measures
Still not enough to acquire the best information about the world
Bias and limited explanatory power
Scientific skepticism
Question authority, intuition and beliefs
Systematic doubt and continual testing
Careful with extreme skepticism/ extreme postmodernity: these are the tools of obfuscation.
Objective Psychoactive Drug Effects
Easily measurable
Subjective Psychoactive Drug Effects
Resistant to measurements, can only be measured indirectly
