AIMS To clarify the role of acetate in neurochemical mechanisms of the initial (inborn) tolerance to ethanol. METHODS Rats with low and high inborn tolerance to hypnotic effect of ethanol were used. In the brain region homogenates (frontal and parietal cortex, hypothalamus, striatum, medulla oblongata) and brain cortex synaptosomes, the levels of acetate, acetyl-CoA, acetylcholine (AcH), the ...

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...

Scoparia dulcis Linn. (SD) is a perennial herb that has been well studied for its antioxidant, anti-inflammatory, antidiabetic, and hepatoprotective effects. However, scientific information on SD regarding the neuropharmacological effect is limited. This study evaluated the sedative and hypnotic effect of the ethanolic extract of whole plants of Scoparia dulcis (EESD). For this purpose, the who...

Control and awareness seem intimately related (e.g. Norman and Shallice 1986; Jacoby 1991). Of course, some forms of control occur quite unconsciously (plausibly, for example , the detailed configuring of motor movements; Milner and Goodale 1995). However, there are some forms of control, such as planning or overcoming strong response tendencies (the 'executive tasks' of Norman and Shallice) th...

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...
