ResultsThe Salvia-induced shifts in EEG compared to the baseline signature were striking.The most consistent effects observed were: In 6 of 8 participants, Alpha power (9-10 Hz) was significantly reduced (M ¼ 63%, p < .04,twotailed correlated samples) and alpha spindling disorganized.In 4 participants, abundant large amplitude slow cortical potentials (SCPs) were recorded at many cortical...

This study reports a new measure of psychotomimetic states in the context of cannabis and ketamine use. The Psychotomimetic States Inventory (PSI) has sub-scales of Delusory Thinking, Perceptual Distortions, Cognitive Disorganization, Anhedonia, Mania and Paranoia. The PSI was administered in two independent group, repeated measures designs: an experimental study of ketamine and a naturalistic...

Epilepsy research suffers from a deficiency of systematic studies concerning the phenomenology of the contents of consciousness during seizures, partially because of the lack of suitable research methods. The Phenomenology of Consciousness Inventory (PCI), a standardized, valid, and reliable questionnaire, was used here to study which dimensions of the contents of consciousness are distorted...

The history of serotonin research is closely related to the study of hallucinogenic drugs that function as agonists at serotonin-2A receptors. The fundamental idea that psychotic states seen in psychiatric disorders such as schizophrenia might be attributable, in part, to abnormalities in serotonergic systems began with the almost simultaneous discovery of lysergic acid diethylamide (LSD),...

Contemporary researchers have tended to examine dysfunction among the lives of persons with schizophrenia as a matter of the impact of biological and social forces. While this has greatly advanced the knowledge base, any account of schizophrenia without a full consideration of the illness's first-person dimensions risks missing that schizophrenia is a disorder that interrupts the lives of...

Serotonin (5-HT) release is the primary pharmacological mechanism of 3,4-methylenedioxymethamphetamine (MDMA, ‘ecstasy’) action in the primate brain. Dopamine release and direct stimulation of dopamine D2 and serotonin 5-HT 2A receptors also contributes to the overall action of MDMA. The role of 5-HT 1A receptors in the human psychopharmacology of MDMA, however, has not yet been elucidated. In...

The human brain is probably the most complicated single structure in the biological universe. The cerebral cortex that is traditionally connected with consciousness is extremely complex. The brain contains approximately 1,000,000 km of nerve fibers, indicating its enormous complexity and which makes it difficult for scientists to reveal the function of the brain. In this paper, we propose a new...

The psychoactive properties of N,N-dimethyltryptamine (DMT) 1a are known to induce altered states of consciousness in humans. This particular attribute attracts great interest from a variety of scientific and also clandestine communities. Our recent research has confirmed that DMT reacts with dichloromethane (DCM), either as a result of work-up or storage to give a quaternary N-chloromethyl...

Sartre's brilliant and indefatigable investigations of consciousness are less well read than they used to be. But the advent of positron emission tomography, functional magnetic resonance imaging, and magnetoencephalography has enabled neuroscientist to look at the functioning brain during tasks requiring consciousness, and they are ratifying many of the insights that Sartre obtained from...
