Only little research has been conducted on the pharmacological underpinnings of metacognition. Here, we tested the modulatory effects of a single intravenous dose (100 ng/ml) of the N-methyl-D-aspartate-glutamate-receptor antagonist ketamine, a compound known to induce altered states of consciousness, on metacognition and its neural correlates. Fifty-three young, healthy adults completed two...

Abnormalities in the endocrine and immune systems are well documented in patients with Major Depressive Disorder (MDD), however, the mechanisms by which the novel antidepressant treatment, ketamine, influences these physiological systems are unclear. This study examined the effects of repeated ketamine infusions on the endocrine and immune systems using the peripheral biomarkers C-reactive...

Traditionally, ketamine was considered useful as a dissociative anesthetic. More recently, ketamine has been examined for its effects as a fast-acting antidepressant, for treatment-resistant depression, and as a non-opiate treatment of chronic pain. Unfortunately, ketamine has enjoyed popularity as a recreational drug among both adolescents and young adults. While some research suggests the use...
