Adolescent consumption of caffeine, the most commonly used psychoactive stimulant in the world, has increased strikingly in recent years. Caffeine use has been associated with illicit drug use and risky behaviors, but whether consumption of caffeine during adolescence has effects on the mature brain is controversial. In this podcast, author Ryan Bachtell discusses his recent study, which found that consumption of caffeine by male adolescent rats results in enduring neurobiological effects in a key reward area in the brain and an increased sensitivity to cocaine in adulthood.

In this issue of Neuropsychopharmacology Reviews, entitled Neurodevelopment and the Origins of Brain Disorders, subject discipline experts provide both experimental highlights and perspectives on the current understanding of basic mechanisms of neurodevelopment, the influence of developmental disruptions on childhood and adult-onset brain and behavioral disorders, and the emerging promise of translation into treatments. In this podcast, the editors of this year's volume, Pat Levitt (Simms/Mann Chair in Development Neurogenetics, Children's Hospital Los Angeles) and Jeremy Veenstra-VanderWeele (Mortimer D Sackler Associate Professor of Psychiatry, Columbia University/New York State Psychiatric Institute), discuss the recent research and its future applications.

Marijuana use for medical purposes is becoming increasingly common in the U.S., and doctors prescribe it for ills ranging from headaches to insomnia. And yet, there is little scientific data supporting its medical use. In this podcast, Drs. Margaret Haney and Eden Evins discuss the relationship between cannabis use and two psychiatric disorders: post-traumatic stress disorder and psychotic illnesses, particularly schizophrenia.

There has been a recent and notable increase in the non-medical use of new psychoactive substances (NPS), or "designer drugs." Unlike classic drugs of abuse, many NPS were initially developed for research purposes. In this podcast, Drs. Michael Baumann and Nora Volkow discuss the complexities of working with these substances and how, given their genesis, research with NPS could be considered "dual use;" or, potentially utilized for both beneficial and malicious purposes.

"Impact of Stress on the Brain: Pathology, Treatment and Prevention," the 2016 issue of Neuropsychopharmacology Reviews, focuses on advances in our understanding of the impact of stress on the brain: From pathology to circuits, treatment to prevention. Emerging data from genetics, epigenetics, neural circuit and intergenerational models, animal models, and neuroimaging all suggest that stress affects the brain in a variety of dynamic and often long-lasting ways. The effects of these processes on developmental risk for pathology are particularly notable.

The National Institutes of Health recently published a statement requiring sex as a biological variable in studies. This is in part simply because it's good science, and in part to correct for decades in which both animal and human studies were largely conducted with male subjects. In their review paper responding to this statement, Dr. Tracy Bale and Dr. Neill Epperson discuss how sex has a direct impact on brain development, and how it results in a sexually dimorphic brain: meaning there are physical differences between males and females. Listen to the latest BrainPod, Neuropsychopharmacology's official podcast, to hear Dr. Bale and Dr. Epperson discuss this topic!

Brainpod January 2017: Sex as a Biological Variable: Who, What, When, Why, and How

The recreational drug MDMA, also known as Ecstasy or Molly, is particularly popular in social settings and raves, in large part because of how socially connected it makes the users feel. It’s being studied for use in psychotherapy —there’s a phase III clinical trial for the use of MDMA to treat PTSD. What’s clear is that the drug affects how users experience social interactions. But there are questions: Does the drug make positive social interactions feel better, or reduce the negative feelings associated with negative social interactions?

It’s widely understood that early life adversity has an impact on mental illness and cognitive problems later in life. There are theories as to the mechanisms of how this   works, but it’s difficult to test in humans. Tallie Baram is a professor of neurophysiology and biophysics at the UC Irvine department of pediatrics. And she co-authored a recent study in the journal Neuropsychopharmacology with Ali Mortazavi, professor of  developmental and cell biology at UC Irvine. Dr. Baram says that imaging studies show changes in brain structure and circuits, and cognitive and emotional tests also demonstrate a change in function. But it’s difficult to study the mechanism, to try to understand how this is happening, because scientists can’t take samples of brain tissue to determine how and when genes are expressed.

It’s known that there’s a relationship between post-traumatic stress disorder, or PTSD, and a higher rate of opioid abuse. What isn’t understood, though, is what that relationship is. Does PTSD cause people to turn to opioids in particular among all the potential drugs of abuse, or is there something about opioid use that makes users particularly sensitive to trauma? This is just what Michael Fanselow, professor in the psychology and psychiatry departments at UCLA, and his colleagues investigated for a recent study in the journal Neuropsychopharmacology.

A number of drugs that are used recreationally are now being studied for their use in psychopharmacology. But while the ways in which these drugs are similar or different has been described anecdotally by recreational users, they haven’t been studied in comparison to one another. Dr. Matthias Liechti and his team of researchers recently published a study in the journal Neuropsychopharmacology, in which 28 healthy subjects, men and women, take doses of LSD, MDMA, amphetamines, and a placebo over four different sessions. Dr. Liechti says this blinding is important; in other studies, participants either have taken a drug or a placebo and can tell when they’re taking the drug. But in this case they don’t know which drug they’re taking, which allows the effects of the drugs to be compared against each other. Take a listen to find out more!

Over the past decades, there’s clearly been a dramatic increase in the amount of time people spend online using social networking sites. For instance, Facebook and Instagram have literally billions of users. At the same time, there’s been a rise in mental health issues for young people from teens through their mid 20s. The rise in these issues has been seen particularly for Millenials and the I generation, both of which grew up with increased access to and use of social networking sites. As a result, some have drawn the conclusion that perhaps the two are linked, and the rise in mental health issues is linked causally to the increase in time spent online, and so treatment should involve reducing social networking use. Dr. Kiara Timpano, associate professor at the University of Miami department of psychology, and Dr. Courtney Beard, co-director of the clinical research program in behavioral health at McLean Hospital and associate professor of psychiatry at Harvard Medical School, reviewed the literature.
