Psilocybin-Induced Decrease in Amygdala Reactivity Correlates with Enhanced Positive Mood in Healthy Volunteers

Biological Psychiatry April 26, 2014 Rainer Kraehenmann, Katrin H. Preller, Milan Scheidegger et al. 325 citations

BackgroundThe amygdala is a key structure in serotonergic emotion-processing circuits. In healthy volunteers, acute administration of the serotonin 1A/2A/2C receptor agonist psilocybin reduces neural responses to negative stimuli and induces mood changes toward positive states. However, it is little-known whether psilocybin reduces amygdala reactivity to negative stimuli and whether any change...

NEUROBIOLOGY OF STRESS, DEPRESSION, AND RAPID ACTING ANTIDEPRESSANTS: REMODELING SYNAPTIC CONNECTIONS

Depression and Anxiety March 10, 2014 Ronald S. Duman 213 citations

Stress and depression are associated with atrophy and loss of neurons in limbic and cortical brain regions that could contribute to the symptoms of depression. Typical monoamine reuptake inhibitor antidepressants have only modest efficacy and require long-term treatment, and are only weakly effective in blocking or reversing these structural changes caused by stress. Recent findings demonstrate...

MDMA is certainly damaging after 25 years of empirical research: a reply and refutation of Doblin et al. (2014).

Human Psychopharmacology: Clinical and Experimental March 2014 Andrew C. Parrott

Human Psychopharmacology recently published my review into the increase in empirical knowledge about the human psychobiology of MDMA over the past 25 years (Parrott, 2013a). Deficits have been demonstrated in retrospective memory, prospective memory, higher cognition, complex visual processing, sleep architecture, sleep apnoea, pain, neurohormonal activity, and psychiatric status. Neuroimaging...

Behavioral and neurochemical pharmacology of six psychoactive substituted phenethylamines: mouse locomotion, rat drug discrimination and in vitro receptor and transporter binding and function.

Psychopharmacology March 1, 2014 Amy J. Eshleman, Michael J Forster, Katherine M. Wolfrum et al. 72 citations

Psychoactive-substituted phenethylamines 2,5-dimethoxy-4-chlorophenethylamine (2C-C); 2,5-dimethoxy-4-methylphenethylamine (2C-D); 2,5-dimethoxy-4-ethylphenethylamine (2C-E); 2,5-dimethoxy-4-iodophenethylamine (2C-I); 2,5-dimethoxy-4-ethylthiophenethylamine (2C-T-2); and 2,5-dimethoxy-4-chloroamphetamine (DOC) are used recreationally and may have deleterious side effects. This study compares...

How MDMA's Pharmacology and Pharmacokinetics Drive Desired Effects and Harms

The Journal of Clinical Pharmacology January 16, 2014 C. Michael White 58 citations

Abstract 3,4‐Methylenedioxymethamphetamine (MDMA) is an agent of abuse that has been used by over 16 million Americans. Increased energy, elevated mood, bonding with others, and psychedelic effects are desired effects while liver damage, extended depressed mood, sexual assault, rhabdomyolysis, serotonin syndrome, multiorgan failure, cardiovascular events, arrhythmias, and death are possible...

Glutamate Receptor Antagonists as Fast-Acting Therapeutic Alternatives for the Treatment of Depression: Ketamine and Other Compounds

The Annual Review of Pharmacology and Toxicology January 6, 2014 Mark J. Niciu, Ioline D. Henter, David A. Luckenbaugh et al. 166 citations

The N-methyl-D-aspartate (NMDA) receptor antagonist ketamine has rapid and potent antidepressant effects in treatment-resistant major depressive disorder and bipolar depression. These effects are in direct contrast to the more modest effects seen after weeks of treatment with classic monoaminergic antidepressants. Numerous open-label and case studies similarly validate ketamine's antidepressant...

Behavioral and neurochemical effects of repeated MDMA administration during late adolescence in the rat.

Progress in Neuro-Psychopharmacology and Biological Psychiatry January 3, 2014 Brittney M Cox, Mrudang M Shah, Teri Cichon et al.

Adolescents and young adults disproportionately abuse 3,4-methylenedioxymethamphetamine (MDMA; 'Ecstasy'); however, since most MDMA research has concentrated on adults, the effects of MDMA on the developing brain remain obscure. Therefore, we evaluated place conditioning to MDMA (or saline) during late adolescence and assessed anxiety-like behavior and monoamine levels during abstinence. Rats...

Maternal MDMA administration in mice leads to neonatal growth delay

The Journal of Toxicological Sciences 2014 Asuka Kaizaki, Sachiko Tanaka, Takemi Yoshida et al. 18 citations

The psychoactive recreational drug 3,4-methylenedioxymethamphetamine (MDMA) is widely abused. The fact that MDMA induces neurotoxic damage in serotonergic nerve endings is well known. However, the effects of MDMA on pregnant and neonatal animals remain unknown. Therefore, we studied the effects of gestational exposure to MDMA on birth, growth, and behavior of pups. Female BALB/c mice were...

Effects of Stress and MDMA on Hippocampal Gene Expression

BioMed Research International 2014 Georg F. Weber, Bethann N. Johnson, Bryan K. Yamamoto et al. 19 citations

MDMA (3,4-methylenedioxymethamphetamine) is a substituted amphetamine and popular drug of abuse. Its mood-enhancing short-term effects may prompt its consumption under stress. Clinical studies indicate that MDMA treatment may mitigate the symptoms of stress disorders such as posttraumatic stress syndrome (PTSD). On the other hand, repeated administration of MDMA results in persistent deficits...

The Potential Dangers of Using MDMA for Psychotherapy

Journal of Psychoactive Drugs 2014 A. C. Parrott 60 citations

MDMA has properties that may make it attractive for psychotherapy, although many of its effects are potentially problematic. These contrasting effects will be critically reviewed in order to assess whether MDMA could be safe for clinical usage. Early studies from the 1980s noted that MDMA was an entactogen, engendering feelings of love and warmth. However, negative experiences can also occur...
