“…Laidlaw (1993) assessed hypnotizability in a group of neurological patients who had suffered closed head injuries, but did not specifically consider laterality. Relatedly, Persinger and his colleagues (Healey et al, 1996; Tiller and Persinger, 1994) found that the brief application of a weak pulsed magnetic field over the right temporal lobe, inducing activity resembling complex partial epileptic-like seizures, increased hypnotizability in neurologically intact subjects. The present study sought to contribute to neuropsychological investigations of hypnosis by examining hypnotic susceptibility in patients with clearly lateralized brain damage secondary to stroke.…”

Speculations about the neural substrates of hypnosis have often focused on the right hemisphere, implying that right-hemisphere damage should impair hypnotic responsiveness more than left-hemisphere damage. The present study examined the performance of a patient who suffered a stroke destroying most of his left hemisphere, on slightly modified versions of two hypnotizability scales. This patient was at least modestly hypnotizable, as indicated in particular by the arm rigidity and age regression items, suggesting that hypnosis can be mediated by the right hemisphere alone -- provided that the language capacities normally found in the left hemisphere remain available. A further study of 16 patients with unilateral strokes of the left or right hemisphere found no substantial differences in hypnotizability between the two groups. Future neuropsychological studies of hypnosis might explore the dorsal/ventral or anterior/posterior dichotomies, with special emphasis on the role of prefrontal cortex.

“…If weak MFs have an effect upon nociceptive processing, it may well be of interest to explore its use in novel analgesic processing, such as hypnotic or placebo analgesia, particularly since opiate antagonist naloxone has been shown to attenuate MF-induced analgesia [Thomas et al, 1997a,b] as well as placebo analgesia [Amanzio and Benedetti, 1999;Amanzio et al, 2001]. MFs could also be used to augment or supplement the induction of hypnotic analgesia, as some previous studies have suggested [Tiller et al, 1994;Healey et al, 1996].…”

The investigation of weak (<500 microT), extremely low frequency (ELF, 0-300 Hz) magnetic field (MF) exposure upon human cognition and electrophysiology has yielded incomplete and contradictory evidence that MFs interact with human biology. This may be due to the small number of studies undertaken examining ELF MF effects upon the human electroencephalogram (EEG), and the associated analysis of evoked related potentials (ERPs). Relatively few studies have examined how MF exposure may affect cognitive and perceptual processing in human subjects. The introduction of this review considers some of the recent studies of ELF MF exposure upon the EEG, ERPs and cognitive and perceptual tasks. We also consider some of the confounding factors within current human MF studies and suggest some new strategies for further experimentation.

Preferential exposure over the right hemisphere has been associated with increased scores for hypnosis induction capacity or suggestibility [8,9]. This sensitivity of the right hemisphere to weak experimentally generated and natural geomagnetic fields has been reported frequently [10].…”

Abstract:The audible energies associated with intense meaningful words significantly affect our experience and responses. Personal listening devices (such as music players) emit weak-intensity magnetic fields, that are shadowed by the sonic patterns, which have been associated with the induction of affective experiences experimentally within the laboratory. In the present study only the electromagnetic (EM) equivalents (1 to 5 microTesla) of emotional words as well as intensity-matched 60 Hz sine wave fields were presented across the temporal lobes. The EM equivalents were produced by converting a digital audio signal into an electromagnetic field. We found that subjects selected significantly more words with the same pleasantness as the target word presented as an EM equivalent. We also found an enhancement of the effect for the presentation of unpleasant-active words. These results suggest that the electromagnetic component of the spoken word from electronics may mediate emotional information that affects decision-making.
