- 1Is drug addiction just one form of a compulsive, maladaptive behaviour?- objects/habits (nail and pen biting)
- food (approach and avoidance)
- Exercise regimes
- Hoarding
- gambling
- sex - 2Drug addiction can be defined as :a syndrome in which a drug is given a higher priority than other behaviours that one had higher value
- its an extreme form, addiction is associated with compulsive drug using disorder and exhibits the characteristics of a chronic relapsing disorder - 3Robinson and Barridge - 1993- neural basis of drug craving: intensive sensitization
- takes more to feel better
- sensitization of neural system to incentives - 4Motivated behaviours- things that make you do things
- sex, food, water, behaviour, temp regulation - 52 phases of motivated behaviourappetitive phase
consumatory phase - 6appetitive phase- what do you mean when you have an appetite - go to food
- non specific
- behaviour is similar to the goal (external stimulus)
- anticipatory
- hunger, thirst, sexual desire (want need and crave) - 7Consumatory phase- specific behaviours
- behaviour necessary for successful interaction with goal
- performance
- eat drink fuck - 8sooty the mouseappetitive (tunnel)
consumatory (orgy) - 9Where is wanting in the brain?- the subjective experience of needing or desiring something
- dopamine neurons in brainstem to frontal lobe
- increases locomotor and environmental cues
- cell bodies in mid brain, project axons into limbic system and the prefrontal cortex - 10What about pleasure in the brain?- wanting and liking arent the same
- liking (pleasure): the subjective experience of something being good or pleasurable
- euphoria or positive emotion
- warm and fuzzies: love and shit - 112 main candidates for pleasureendogenous opioids and oxytocin
- 12Operant conditioning (B.F. Skinner)- animal operates the system
- they reach criteria and get reward
- doesnt allow pleasure and wanting - 13self stimulationpress lever and get shocked
- 14Measuring sexual desire (Everitt, 1990)- lever, drop, snatch
- keeps pushing lever - 15what does mitchell and gratton, 1992 say?more dopamine in synapse = change in behaviour
- 16Translating to maladaptive goals if incentive is provided:- increased activity
- increased novel reaction
- increased attention to cues - 17single injection of d-amphetamine- psychostimulant
- 1. cause dopamine to be released
2. blocks reuptake of dopamine - 18repeated drug use- produces two oppositional effects that are not mutually exclusive
- 19habituation and tolerancedecreases the effects over repeated administration
- 20facilitation and sensitizationincrease in drug effects over repeated administration
- 21Reflex pathway of drugsDrugs = DA release in forebrain sites
- WANTING (increase in drug oriented behaviours)
- repeated use = sensitization = increased wanting
- CRAVING = ADDICTING - 22Why dont all drug encounter lead to drug use?conditioned control of wanting and taking behaviour:
- post surgical pain
- Vietnam War
- Causal experimentation
- Bar smoker
- albert and cheese - 23When non human animals are given drugs, they show?- increased initial response to the drug
- enhanced sensitization to the drug
- strong, long lasting responses to the environment - 24Pavlov and classical conditioning- measuring effects of context
- conditioning the environment where the drug is being taken - 25Childress and Quitting (1999)- 7 years to finally quit but probably longer
- 26why relapse?- exposure to environment of previous drug
- taking drug again (or close)
- stress - 27***EVERYONE HAS THE POTENTIAL TO GET INTO A COMPULSIVE PATTERN***yeah dude
