We summarised and tabulated the literature dealing with the electroencephalogram in pilot selection published since a review in 1976. The incidence of seizure development in healthy groups with epileptiform discharges in their EEGs was found to be very low. An alternative interpretation is offered of the significance of epileptiform discharges in these… (More)
Lateral preferences for the use of eye, hand, and foot were assessed in 17 male and female albino subjects, aged 15 to 52 yr. Visual evoked potential (VEP) recordings suggested that optic fibres were abnormally decussated in these subjects, as others have shown. Fewer albino subjects showed the lateral preference for the use of hand/eye and foot/eye similar… (More)
Pattern reversal visual evoked potentials were recorded in a dentist who had abused nitrous oxide while he showed neurologic impairment and during recovery. The latency of the major positive peak (P100) remained constant during both phases. However, the amplitude of this peak was markedly reduced during the stage of neurologic involvement, and increased… (More)
Previous studies have shown a low incidence of clinical seizure development in healthy individuals with EEG epileptiform discharge activity. This has tended to de-emphasise the role of the EEG in screening pilots. A call is made for consideration of impairment of function associated with epileptiform discharges as a relevant factor in determination of… (More)
OBJECTIVE To identify the frequency and qualitative characteristics of marketing claims made by Canadian chiropractors, naturopaths, homeopaths and acupuncturists relating to the diagnosis and treatment of allergy and asthma.

The clinical ambit of the electro-encephalogram (EEG) is discussed for the benefit of practitioners who do not regularly use this procedure. Some topics covered are: what is measured by an EEG; the report; epileptiform and nonspecific signs in relation to a diagnosis of epilepsy; and limitations and advantages of the EEG.
