Anecdotal evidence indicates that supplementation with vitamin B6 (pyridoxine) before bed can enhance dream vividness and recall. In a single pilot study, Ebben, Lequerica, and Spielman (2002) found that vitamin B6 had a dose-dependent effect of increasing scores on a composite measure of dream vividness, bizarreness, emotionality, and color. The present research replicated this study using a...
This review seeks to bridge the gap between the separate but interacting mechanisms of emotion regulation and cognition, as well as their potential relationship with mindfulness meditation tools. By way of mindfulness meditation, individuals can learn how to regulate their emotions in a way that aversive stimuli will be viewed objectively; thus, the person can be free of attachment from said...
This chapter examines the philosophy of mind in relation to psychosis. It begins by re-appraising the work of Karl Jaspers. Jaspers has been taken as an apologist for biological psychiatry. However, this is ironic, as Jaspers was, as an existential philosopher, interested in the personal experience of psychosis. His account of the phenomenology of psychosis is reappraised. The philosophical...
New psychoactive substances (NPSs), i.e., newly designed substances with chemical residues that are slightly different from those of known psychoactive substances, have been emerging since the late 2000s, and social problems related to the use of these substances are increasing globally. Two such NPSs are 4-chloro-2,5-dimethoxyamphetamine (DOC), a psychedelic substance that is structurally...
Ayahuasca is a hallucinogenic beverage produced from the decoction of Banisteriopsis caapi (Bc) and Psychotria viridis (Pv), β-carboline- and N,N-dimethyltryptamine(DMT)-containing plants, respectively. Accumulating evidence suggests that ayahuasca may have therapeutic effects on ethanol abuse. It is not known, however, whether its effects are dependent on the presence of DMT or if...
This article will discuss how the ‘enactive’ approach to cognition and psychological processes can help further clarifying and developing a more heuristic framework for the understanding of severe mental disorders, in this case, depression and schizophrenia. Furthermore, enactivismwill serve as a framework that comprehends depressions and schizophrenia as disorders that encompass three...
In this report, we describe a case of a patient with substance-induced anxiety disorder occurring after a single dose of 3,4-methylenedioxymethamphetamine. Furthermore, we describe the use and efficacy of the Primary Care Behavioral Health model, a collaborative approach to integrative primary mental health care, in evaluating and treating this rare mental health disorder. Three days following...
Forced abstinence from chronic two bottle-choice ethanol drinking produces the development of negative affective states in female C57BL/6J mice. We previously reported that this disrupted behavior is acutely reversed by administration of ketamine 30 min-prior to testing. Here we assessed whether ketamine can be used as an inoculant against the development of abstinence- dependent affective...
For a number of complex reasons, humans are fascinated by drugs and altered states. Even if only momentarily, psychoactive substances lift people out of the ennui and pain of their everyday lives and, in some cases, introduce them to new visions of reality. It is no surprise, therefore, that the use of recreational drugs is rising. While, sadly, this also means that levels of addiction are...
Hallucinations possess two main components: (i) a sensory content; (ii) a sense that the sensory content is real. Influential models of schizophrenic hallucination claim that both the sensory content and the sense of reality can be explained in terms of metacognitive dysfunction. This chapter assesses whether such a claim holds for schizophrenic and drug-induced hallucinations; it further...
