Behavioral science 4.4-5 Flashcards
Alcohol
Increase his activity of the GABA receptor which generalize his brain inhibition. Alcohol increases dopamine levels and also results in alcohol myopia, loss of the ability to recognize consequences of actions
Wernick Korsakoff syndrome
And effect of alcoholism that impairs memory and mental status
Benzodiazepines
Anxiety reducing and sleep medication’s function by increasing GABA receptor activity causing a sense of relaxation
Amphetamines
Cause increased arousal by increasing release of dopamine, norepinephrine, and serotonin.
Cocaine
Decreases reuptake of dopamine, norepinephrine, and serotonin
Ecstasy
Hallucinogen combined with An amphetamine
Opiates
Naturally occurring forms of opium including morphine and codeine
Bind to opioid receptors in the peripheral and central nervous system causing a decrease in pain and sense of euphoria
Opioids
Semi-synthetic derivatives of opium
Bind to opioid receptors in the peripheral and central nervous system causing a decrease in pain and sense of euphoria
Heroin
Metabolized to morphine
Hallucinogens
Function is unknown but there is a complex interaction between various neurotransmitters
THC in marijuana
Inhibits GABA activity indirectly increasing dopamine activity
Mesolimbic reward pathway
A dopaminergic pathways in the brain that sponsors drug addiction.
Involves the nucleus accumbens, Ventral tegmental area, and medial forebrain bundle.
Attention
Concentrating on one aspect of a sensory environment
Selective attention
Focusing on one part of a sensory environment while ignoring other stimuli
Cocktail party phenomenon
Shows that selective attention is more like a filter allowing us to focus on one thing while allowing other stimuli to be processed in the background
