Drug Addiction Addictive Drugs
4,264 wordsThe emphasis is on biological mechanisms underlying addiction, although some other factors influencing drug addiction will also be discussed. The presentation is limited primarily to psychomotor stimulants (e. g. , amphetamine, cocaine) and opiates (e. g. , heroin, morphine) for two reasons. First, considerable knowledge has been gained during the past 15 years regarding the neurobiological mechanisms mediating their addictive properties. Second, these two pharmacological classes represent the b...

The Addiction Research Center Inventory, an empirically derived test designed to measure the subjective effects of addictive drugs, detects the mood-elevating effects of psychomotor stimulants and opiates on the same scale (see Haertzen and Hickey 1987). On the other hand, the subjective-effects of these two drug classes can be easily distinguished. This is not surprising considering that ex-addicts report a preference for heroin over morphine (Martin and Fraser 1961), even though ...

No language representations which passed through allowed levels of excitation were generated. Conversely, all other erogenic events ran their normal course even when their results conflicted with the results of the erogenic event. Thus, for instance, the subject can write something (which is the result of the trapped energy) and provide, verbally, an answer which starkly contradicts the wr...

Organ Transplant Organ Donation
797 wordsA person that receives an organ transplant almost always requires several complementary goods. One obvious good is the medical care received for the actual transplant and for follow-up doctor's visits. For most people who undergo an organ or tissue transplant the quality of their life and general overall health improves following the transplant. Persons who receive a transplant are frequently required to take a series of medications that suppress their immune system and prevent their body from r...

Obsessive Compulsive Freud

Numerous explanations have been hitherto offered: That what we, humans, call a soul is the way that we experience the workings of our brain (introspection experienced). This often leads to infinite regressions. That the soul is an epiphenomenon, the software result of a hardware complexity (much the same way as temperature, volume and...

Lymph Nodes Nervous System
1,517 wordsStress is the nonspecific response of the body to any demand made on it. Each demand made on the body is specific. Each drug or hormone has specific actions, yet they all have one thing in common; they increase the demand for readjustment. This demand is nonspecific; it requires adaptation to a problem. In other words, in addition to their specific actions, all agents to which we are exposed also produce a nonspecific increase in the need to perform adaptive functions to re-establish normality. ...
