Asperugo procumbens L. has been used in Iranian traditional medicine for the refreshing, tranquillizing and mood elevating activities. The present study was undertaken to evaluate the antidepressant and sedative-hypnotic potential of acute administration of the hydroalcoholic extract of this plant in mice. Additionally, the effects of flumazenil on the hypnotic activity of the extracts were eva...

Hypnotic analgesia in some respects resembles opiate analgesia. We tested the hypothesis that some features of hypnotic analgesia are mediated through neuronal pathways activating specific opiate receptors in brain. The opiate antagonist naloxone had no effect on hypnotic analgesia in three subjects. Thus, the hypothesis was not confirmed.

The purpose of this study was to investigate the relationship between quantitative electroencephalograph relative amplitude, relative power and hypnotic susceptibility. Hypnotic susceptibility, measured by the Wickramasekera Experience Inventory, was found to be positively correlated with QEEG theta relative amplitude (r = 0.260, p < .10). In addition, hypnotic susceptibility was found to be ne...

Disparate theoretical viewpoints construe hypnotic suggestibility either as a stable trait, largely determined by underlying cognitive aptitude, or as a flexible skill amenable to attitudinal factors including beliefs and expectations. Circumscribed findings support both views. The present study attempted to consolidate these orthogonal perspectives through the lens of expectancy modification. ...

This study assessed response times and accuracy of motor imagery in waking and hypnotic states and to related responses to hypnotic experiences. The Vividness of Motor Imagery Questionnaire (VMIQ) was administered to 47 participants. A mental walking task was then performed in the waking state. In hypnosis, the same task was included within an imaginary journey after a hypnotic induction. An in...

The last ten years have seen the introduction of many new drugs for the treatme' of psychotic disorders and practically every psychiatric symptom. They are alreat replacing the barbiturates which have been used as sedatives for over 50 years. These drugs aim at influencing the processes concerned in the development of psychiatric illness, e.g. schizophrenia and depression, or at controlling the...

The present study investigated the effectiveness of an operant conditioning approach for increasing hypnotic susceptibility. Results revealed significant increases in hypnotic susceptibility, significant generalization to a new set of more difficult items, and no substantial decrease in the stability of improvement. Attitudinal, motivational, and learning factors were considered in relation to ...

Four important investigations were reported during the latter part of 2001. All address the biological impact of hypnotic interventions. Three of these studies focus specifically on if and how hypnotic interventions affect immune functions. A range of immune assays is employed, from allergic response to blood-based assays of immune functioning during nonlaboratory periods of stress. In all 3 ca...
