Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2009 in the subject Psychology - Biological Psychology, grade: A (100%), New College Durham (Duke University, Department of Psychology and Neuroscience), course: Behavior and Neurochemistry, language: English, abstract: It is the aim of this paper to review and integrate relevant empirical findings and theoretical discussions concerning the molecular and cellular mechanisms and effects of MDMA-induced 5-HT neurotoxicity in laboratory animals. 3,4-methylenedioxymethamphetamine (MDMA) is a derivative of the synthetic psychostimulant methamphetamine (METH). It also shares some structural and pharmacological properties of mescaline, a naturally occurring psychedelic hallucinogen. At the molecular level, all three substances resemble the monoamine neurotransmitters epinephrine (E) and dopamine (DA). They mimic the neurophysiological actions and effects of E and DA, as well as serotonin (5-HT). METH and MDMA do so by binding to, and reversal of monoamine-specific transporter proteins at the presynaptic plasma membrane. While the psychological effects of METH are mainly due its action as a DA release agent and reuptake inhibitor, MDMA primarily affects the serotonergic system. It has a high affinity for the serotonin-specific transporter (SERT), which carries it into the presynaptic neuron. Inside the cell, MDMA inhibits the vesicular monoamine transporter type 2 (VMAT2), pre-venting intracellular 5-HT from being stored in synaptic vesicles. In addition, MDMA phos-phorylates SERT, which causes a reversal of its reuptake function and, hence, non-exocytotic efflux of 5-HT by the means of passive diffusion. Because neurotransmitter release normally only occurs in case of an action potential, and the released transmitter is partly reabsorbed and recycled, the reverse functioning of SERT depletes 5-HT stores. The equivalent effect of METH via reversal of the DA transporter (DAT) has been linked to its neurotoxic properties (Yamamoto & Zhu, 1998). As a derivative of methamphetamine, MDMA is sometimes believed to have inherited the severe dopaminergic neurotoxicity of METH and its parent compound amphetamine. Such neurotoxic potential has been found in mice but not in rats (Colado, O’Shea, and Green, 2004), and remains to be established for non-human primates. The probably most prominent publication claiming that MDMA caused irreversible damage to primate DA neurons (Ricaurte et al., 2002) was shown to be in error and had to be retracted. Instead of a recreational dose of MDMA (3 2 mg/kg), the monkeys had, in fact, been given METH, which, at such doses, is known to be neurotoxic in primates (Villemagne et al., 1998). [...]

This book was released on 1989-12-31 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The variety of viewpoints expressed in this book illustrate the many contro versies surrounding MDMA [1]. On the one hand, the proponents ofMDMA use believe this agent offers a unique psychoactive effect that may have important clinical applications, especially in the field of psychotherapy. On the other hand, the scientific data concerning the neurotoxic effects of the drug are unequivocal. The most striking feature of the human information of MDMA is the paucity of data that has been generated on the drug since it was patented in 1914. As pointed out by Beck (Chapter 6) and others, a clear need exists for better epidemiological and clinical data on MDMA. In the absence of such data, arguments both for and against the cotinued use ofMDMA with humans will be difficult to support. Unfortunately, the currently available data must be used to develop rational policies for potential human users of MDMA. At the present time, there are no data indicating that recreational doses of MDMA permanently damage the human brain. Nonetheless, based on a review of the contents of this book as well as on informal discussions with approximately 200 recreational users of MDMA, the following personal observations suggest that MDMA is radically different from other recreational drugs.
Download or read book Effects of 3 4 methylenedioxymethamphetamine mdma on Cholinergic Neurons in the Rat Brain written by and published by . This book was released on 2005 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: 3,4-Methylenedioxymethamphetamine (MDMA), an amphetamine analog, is a psychomotor stimulant and a popular drug of abuse. The effect of MDMA on the release of the monoamine neurotransmitters serotonin (5-HT) and dopamine (DA) has been well documented. In contrast, very little is known about the influence of MDMA on other neurotransmitter systems. In view of feelings of heightened awareness and behavioral arousal in human MDMA users, and the role of the cholinergic system in processing environmental cues following novel and arousing stimuli, the influence of MDMA on acetylcholine (ACh) release was examined in the prefrontal cortex (PFC) and hippocampus. Using in vivo microdialysis, it was determined that MDMA enhances the release of ACh in the PFC and hippocampus, possibly by mechanisms localized to these brain regions. In addition, it was also determined that MDMA-induced release of ACh in the PFC, but not hippocampus, is mediated by serotonergic and dopaminergic mechanisms. Further studies examining the role of various 5-HT and DA receptors in the MDMA-induced release of ACh in the PFC indicate that receptors of the 5-HT4 and D1 subtype mediate the release of cortical ACh induced by MDMA. Whereas MDMA use has been associated with behavioral activation and cortical arousal immediately following drug intake, in the long term the drug is known to produce significant cognitive impairments. In view of the cognitive impairments following MDMA use and administration, and the central role of ACh in attentional processing and cognition, studies were designed to assess the influence of a neurotoxic regimen of MDMA, on the subsequent stimulation of ACh release in the PFC. Prior treatment with a 5-HT depleting regimen of MDMA resulted in decreased ACh release in response to subsequent administration of MDMA. In contrast, treatment with a neurotoxic regimen of MDMA did not significantly alter the subsequent stimulation of ACh release induced by application of tail pinch or by the novelty of an intruder rat. Thus, results from the present study indicate that although a 5-HT depleting regimen appears to inhibit subsequent MDMA-induced ACh release in the PFC, it has little impact on subsequent stimulation of ACh release by physiological stressors.

Download or read book Behavioral Toxicology written by Bernard Weiss and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioral toxicology is a young discipline in the United States; so young, in fact, that this is one of its first books. Behavioral questions are bound to play a major role in future scientific work and governmental decisions involving the health effects of environmental contaminants and other chemicals. This role springs from two key problems that face scientists and public agencies required to set acceptable exposure standards or to determine criteria for the toxicity of therapeutic chemicals: How do you evaluate effects that may show up only as subtle functional disturbances? And how do you de tect toxic effects early enough so that they may still be reversible, before they produce major damage? The contributions in this book come from a collection of scientists whose interests span a wide variety of problem areas. The focus is largely on me thodological issues because they represent the most immediate concern of the discipline. We expect that this collection of papers will represent a useful source book for behavioral toxicology for some time. For the past few years, the University of Rochester's Department of Radiation Biology and Biophysics has sponsored a series of international conferences on chemical toxicity, partly as a response to concern over the con sequences to health of the rich chemical soup in which we live. This book is based upon presentations made to the fifth of the series. Held in June, 1972, it was the first formal meeting devoted to behavioral toxicology in this country.

Download or read book Homeostatic Control of Brain Function written by Detlev Boison and published by Oxford University Press. This book was released on 2016 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homeostatic Control of Brain Function offers a broad view of brain health and diverse perspectives for potential treatments, targeting key areas such as mitochondria, the immune system, epigenetic changes, and regulatory molecules such as ions, neuropeptides, and neuromodulators. Loss of homeostasis becomes expressed as a diverse array of neurological disorders. Each disorder has multiple comorbidities - with some crossing over several conditions - and often disease-specific treatments remain elusive. When current pharmacological therapies result in ineffective and inadequate outcomes, therapies to restore and maintain homeostatic functions can help improve brain health, no matter the diagnosis. Employing homeostatic therapies may lead to future cures or treatments that address multiple comorbidities. In an age where brain diseases such as Alzheimer's or Parkinson's are ever present, the incorporation of homeostatic techniques could successfully promote better overall brain health. Key Features include · A focus on the homeostatic controls that significantly depend on the way one lives, eats, and drinks. · Highlights from emerging research in non-pharmaceutical therapies including botanical medications, meditation, diet, and exercise. · Incorporation of homeostatic therapies into existing basic and clinical research paradigms. · Extensive scientific basic and clinical research ranging from molecules to disorders. · Emerging practical information for improving homeostasis. · Examples of homeostatic therapies in preventing and delaying dysfunction. Both editors, Detlev Boison and Susan Masino, bring their unique expertise in homeostatic research to the overall scope of this work. This book is accessible to all with an interest in brain health; scientist, clinician, student, and lay reader alike.
