Advances in human neuroimaging have expanded our ability to understand the functioning of the brain, with particular recent advances fostering our analytic capacity to examine networks between the brain’s nerve cells (i.e., neurons) and neuroconnectivity (i.e., neural networks). Relevant to the field of alcoholism, several researchers recently have applied these strategies to groups at genetic...

Alcohol’s Negative Emotional Side: The Role of Stress Neurobiology in Alcohol Use Disorder
Introduction
The word “alcohol” often conjures up positive feelings and associations with fun, socializing, relaxing, and partying. Yet there is another side to drinking alcohol, especially with risky, hazardous levels of consumption. This side is associated with distress and may include anxiety, loneliness, pain, and depressive symptoms.1 This has been labeled the “dark side,” or “negative...
Advances in Electrophysiological Research
The discovery and recording of electrical activity (electroencephalography [EEG]) in the human brain in 1924 by the German physician Hans Berger (Collura 1993; Haas 2003) has led to numerous scientific breakthroughs and clinical applications (Borck 2005; Gloor 1994). Recording brain activity in humans using scalp electrodes provides a noninvasive, sensitive measure of ongoing brain function...
Bridging Animal and Human Models: Translating From (and to) Animal Genetics
Alcoholism is a complex disorder arising from a combination of genetic and environmental factors. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM–IV) (American Psychiatric Association 1994) requires that three of seven criteria be present during a 12-month period for a diagnosis of alcohol dependence. These criteria are tolerance, withdrawal symptoms, loss of control...
A person with alcoholism engages in risky or dangerous drinking despite experiencing serious negative physical and social consequences. Such persistence in pursuing damaging behaviors suggests that the short-term “appetitive” results of drinking (such as intoxication and losing one’s inhibitions) have greater control over the alcoholic’s behavior than do the negative consequences. From a...
Alcohol’s Effects on the Brain: Neuroimaging Results in Humans and Animal Models
Brain imaging technology has allowed researchers to conduct rigorous studies of the dynamic course of alcoholism through periods of drinking, sobriety, and relapse and to gain insights into the effects of chronic alcoholism on the human brain. Magnetic resonance imaging (MRI) studies have distinguished alcohol-related brain effects that are permanent from those that are reversible with abstinence...
Translating Alcohol Research: Opportunities and Challenges
More than 20 years ago, Daniel Koshland compared basic with applied research, stating: “Basic research is the type that is not always practical but often leads to great discoveries. Applied research refines these discoveries into useful products” (Koshland 1993). This statement implies that basic science does not have a direct impact on human health and disease or patient outcome but offers the...
Alcohol consumption during pregnancy can interfere with both embryonic and fetal development, producing a wide range of outcomes that fall under the rubric of fetal alcohol spectrum disorders (FASD). FASD is the nondiagnostic umbrella term used to refer to the full range of effects that can occur following prenatal alcohol exposure. Such exposure can produce a variety of effects, including...
Privacy and Security in Mobile Health (mHealth) Research
Research on the use of mobile technologies for alcohol use problems is a developing field. Rapid technological advances in mobile health (or mHealth) research generate both opportunities and challenges, including how to create scalable systems capable of collecting unprecedented amounts of data and conducting interventions—some in real time—while at the same time protecting the privacy and safety...
Translating Alcohol Research Into Practice - Editor's Note
Translational research helps move basic science and clinical laboratory discoveries toward application in health and medicine. Through controlled experiments, basic scientists use animal models to reproduce disease characteristics caused by an agent—in this case, excessively high exposure to alcohol. Through systematic study and observation, clinical research scientists identify symptomatic and...
