...three main cognitive domains: memory, attention and creativity. At their most basic meaning, memory can be defined as the ability to recall events or learned material; attention, to focus in something while ignoring distracters; and creativity, to conceive original and useful ideas or products (Lanni et al., 2008). There are other types of cognitive enhancers, such as electrical brain stimulation and psychotropic drugs, which will not be discussed in this paper. Many of the medications used by healthy individuals to enhance cognitive abilities were designed for other purposes, specially treating some traits of mental illnesses....

...Drug Addiction Leah Richards PSY326: Research Methods Maleka Hillsman August 27, 2012 The topic that caught my attention when I was reading my choices was “Drug Addiction”. Drug addiction is something that should not be taken lightly by anyone who has a family member or friend with this issue. We often wonder how and what make people turn into being a drug addict. “Drug addiction is rooted in long-term adaptations within the brain that promotes escalating drug use, difficulty quitting, and relapse—all despite the awareness of negative consequences.” With that being said I have always wondered what keep a person going back to their addiction and why can’t they quit. When I read the article and it mention how drug addiction is rooted a light bulb clicked in my head. When something is rooted inside of you whether it is for good or bad it is hard to break. “It was previously hypothesized that addiction was caused in part of an imbalance between an impulsive system that governs appetitive motivation and is driven by immediate rewards on the one hand and a reflective system that regulate and control impulsive according to future pleasurable or aversive consequences.” With this study they were able to predict the hypothesis and see what causes addiction to happen in some cases. I think that the method used in order to see how people become an addict was efficient and it was very precise that made the validity of the experiment a success. It is important to...

...Physiology & Behavior 90 (2007) 274 – 284 Altered sleep–wake cycles and physical performance in athletes Thomas Reilly ⁎, Ben Edwards Research Institute for Sport and Exercise Sciences, Liverpool John Moores University, Henry Cotton Campus, 15-21 Webster Street, Liverpool, L3 2ET, United Kingdom Received 14 August 2006; accepted 4 September 2006 Abstract Sleep–waking cycles are fundamental in human circadian rhythms and their disruption can have consequences for behaviour and performance. Such disturbances occur due to domestic or occupational schedules that do not permit normal sleep quotas, rapid travel across multiple meridians and extreme athletic and recreational endeavours where sleep is restricted or totally deprived. There are methodological issues in quantifying the physiological and performance consequences of alterations in the sleep–wake cycle if the effects on circadian rhythms are to be separated from the fatigue process. Individual requirements for sleep show large variations but chronic reduction in sleep can lead to immuno-suppression. There are still unanswered questions about the sleep needs of athletes, the role of ‘power naps’ and the potential for exercise in improving the quality of sleep. © 2006 Elsevier Inc.

Introduction The sleep–wakefulness cycle is the most discernable of human circadian functions, activity being associated with the hours of daylight and sleep...

...You have just witness “bro science” in action. It’s wellintended. It can also be deadly. The difference between 5 grams and 5 micrograms, depending on the substance, can indeed be the difference between life and death. Where should one get such information? From qualified sources, of course. Not from your bro. Want to know about proper dosage? Look in the medical literature and find out what dosages have been shown through experimentation to render the desired effects. Want to know about a proper manufacturing method? Then you need to read technical manuals written by actual engineers. As much as possible, I’ve pointed you to more qualified sources of information than myself throughout this guide. I’ve deliberately left out information about dosages in order to force you to use this as a starting point rather than a definitive resource. At the same time, I’m obviously encouraging DIY experimentation. Allow me to clear up the apparent contradiction. See, I intend for this report to be, among other things, a bit of a shot across the bow of the troubled ship that is the nutritional supplement industry. Here’s a field that can do so much good but that exhibits so little true innovation. When anyone can privatelabel the same substandard supplements everyone else is selling and “win with better marketing,” it doesn’t seem there’s much incentive to raise the bar. The best way to shake up such a market is to educate the buyers. When consumers are aware of...

...| New York City | Effective | 8 August 1975 [1] | Condition | 40 ratifications | Parties | 185[1] | Depositary | Secretary-General of the United Nations | Languages | Chinese, English, French, Russian and Spanish | Single Convention on Narcotic Drugs at Wikisource | The Single Convention on Narcotic Drugs of 1961 is an international treaty to prohibit production and supply of specific (nominally narcotic) drugs and of drugs with similar effects except under licence for specific purposes, such as medical treatment and research. As noted below, its major effects included updating the Paris Convention of 13 July 1931 to include the vast number of synthetic opioids invented in the intervening thirty years and a mechanism for more easily including new ones. From 1931 to 1961, most of the families of synthetic opioids had been developed, including drugs in whatever way related to methadone, pethidine, morphinans and dextromoramide and related drugs; research on fentanyls and piritramide was also nearing fruition at that point. Earlier treaties had only controlled opium, coca, and derivatives such as morphine, heroin and cocaine. The Single Convention, adopted in 1961, consolidated those treaties and...
