For animals that continued to be reinforced for nondrug responding after onset of the drug stimulus, discrimination of the training stimulus during subsequent training was not disrupted by the testing procedure. Each section yields the most up-to-date information by experts in their fields. Albert Weissman mentioned the problem he tackled with getting rats to discriminate between saline and dilute solutions of aspirin. All synthetic narcotics are purely anti-emetic and are devoid of the initial emetic action. The handbook focuses on the most urgent drug abuse-related problems of today An entire section is devoted to alcohol abuse, including a scientific appraisal of the most common drunk driving defenses, complete with sample calculations. Albert Weissman mentioned the problem he tackled with getting rats to discriminate between saline and dilute solutions of aspirin.
This study suggests that the discriminative stimulus properties of cocaine are mediated by the release of dopamine from the central nervous system. After a preface by the organizer, two experts discuss basic principles in separate chapters. These measures, although useful in detecting anxiolytic drugs, possess several weaknesses. The reader of this volume will find it a good introduction to the utilization of discriminable stimuli induced by drugs. For example, morphine is known to initially cause vomiting and later show a strong anti-emetic property. This is important because the research strategies developed in these laboratories over the last 5 years combine in vitro and in vivo pharmacological technqiues as a means of understanding mechanisms of drug action.
Dews 1955 , Sidman 1955 , and Brady 1956 published some of the first methodologically significant papers, changing the way both psychologists and pharmacologists viewed the analysis of the behavioral actions of drugs. This dose is similar to the one used by Hermosillo, Penagos-Corzo and Pérez-Acosta 2011 to induce selfdiscrimination tasks in rats. Whereas they all produce respiratory depression, with some a rapid tolerance develops which allows for further use to relieve pain without concommitant depression of respiration. Harbans Lal, did seduce me into attending. They had suffered more physical illnesses in the interval and expressed general dissatisfaction with their life achievements. Additional analyses at 30-60 min post-injection suggested qualitative changes in rearing, with high dose animals showing more, but shorter, rears, and a higher frequency of sniffing.
After a preface by the organizer, two experts discuss basic principles in separate chapters. Acquisition of response control by cocaine 1 succeeded in all animals tested, 2 proceeded rapidly, and 3 was associated with a high Commission Error: Omission Error ratio. Cocaine is one of the most widespread illegal stimulants utilized by the human population throughout the world. In these patients blood concentrations were determined after intranasal application of cocaine for anesthetic purposes. The receptor antagonist haloperidol shifted the cocaine dose-response curve to the right and diminished the maximum response. Although some forms of alcohol dependence can be induced experimentally in a variety of laboratory animals, the complete spectrum of alcoholism with all of its physical, psychological, and social implications occurs only in man. Stimulus generalization experiments were carried out with six inhibitor drugs of monoamine oxidase.
This hypothesis was tested by injecting small amounts of anxiogenic or anxiolytic drugs into the brain and comparing their ability to mimic or block, respectively, the response to pentylenetetrazol, observed after systemic injection. Recently, a number of anxiogenic drugs have been described. Collectively, the papers in this volume reflect the current status of knowledge in the rapidly expanding field of behavioral pharmacology. Findings suggest that the graded generalization gradients generated in a drug discrimination procedure accurately reflect both the limits of the organism and the limits of the behavioral response capabilities established by the procedure. The relationship between drug doses milligrams of hydrochloride salt per kilogram body weight and percentage occupancy of the dopamine transporter was indistinguishable for cocaine and methylphenidate, and corresponded to about 50% occupancy at 0. Locomotor activity was measured in a photocell apparatus.
Thus it is appropriate now to take a closer look at this statistical tool. Tryptamine is a common substrate for both type A and type B monoamine oxidase, so that tryptamine potentiation may serve to determine the relative specificity of the doses at which the inhibitor drugs generalized with cocaine. After a preface by the organizer, two experts discuss basic principles in separate chapters. A common theme underlying the chapter in this volume is the recognition that drugs can act as stimuli, in much the same manner as external events do. The catecholamine depletor, reserpine, shifted the dose response curve to the right and diminished the maximum response.
Cocaine use has been associated with a number of psychiatric disturbances, and an emerging literature attests to its ability to enhance anxiety-like behaviors in animal models. One of these chapters places emphasis on the drugs; the other places emphasis on the induced cues and states. Methylphenidate, d-amphetamine and apomorphine generalized to cocaine. One of these chapters places emphasis on the drugs; the other places emphasis on the induced cues and states. Under ordinary circumstances, the animals could not perform this task. As with nonhuman research subjects, cocaine was consistently chosen over saline by all subjects tested.
Although narcotic drugs were originally natural products, many new drugs are synthetic. The scientific discussion, phar-macokinetic, pharmacological, and analytical, is well tied to the behavioral aspects of substances of abuse, making this a unique publication. Although emphasis is placed on the methodological aspects of assessing drug reinforcement, some of the scientific conclusions derived from using these techniques are also presented. This paper reports preliminary results from a multidisciplinary study of the actions of cocaine in man. These data indicate that when a small dose of cocaine is used as the basis of discrimination training, the discriminative stimulus that it produces is qualitatively and quantitatively similar to that produced by small doses of amphetamine, is still discriminated with a large dose of cocaine, and is dissimilar to the discriminative stimulus produced by pentylenetetrazol. In a sense, Al had created a model of the human arthritic who can jolly well tell if you have given him an aspirin or a salt tablet.
The third section of the paper reports blood concentrations found in normal subjects given cocaine as part of an experimental procedure in which a multiplicity of physiological measures are compared with the amount of cocaine present in the blood. Organized into 12 chapters, this volume begins with an overview of the effects of antidepressant drugs on norepinephrine metabolism. Thirdly, these drugs also share some behavioural effects. It was found that the subjects who had shown spike wave activity in the electroencephalogram-or generalized seizures-had done well in all respects during the interval. The organizer of the symposium on discriminable stimuli induced by drugs, Dr. Cocaine-induced hyperthermia did not predict speed of acquisition reliably, nor did cocaine's effects on operant responding.
During the last three days we have seen several breast cancer survival curves presented by a variety of speakers. Accordingly, the papers focus on the mechanisms by which these stimuli are transduced at different levels of analysis, such as the behavioral, pharmacological, and molecular levels. The high dose cocaine enhancement of sniffing was strongly associated with rear and stand behaviors, but also occurred while the animal was crouching. This edited collection offers a lasting framework for interpreting the results of current experimental findings. Author by : Louie S.
