“…As the spontaneous EEG (Hill, 1963), the AAR (Milstein et al, 1969) and the averaged evoked response (Dustman and Beck, 1965) vary with age during childhood and adolescence, and as advancing age and acquired organic brain disease affect these measures, the age range of the subjects was limited to 19-40. As menstruation also affects the EEG (Margerison, Anderson, and Dawson, 1964), the study was confined to males, all of whom were medically and psychiatrically healthy.…”

Many attempts have been made to relate individual differences in the background electroencephalogram (EEG) to various psychiatric conditions (Glaser, 1963;Hill, 1963;Wilson, 1965) and equivalent investigations have recently been carried out with the averaged evoked response waveform (Shagass and Schwartz, 1961, 1962Jones et al, 1965;Callaway, Jones, and Donchin, 1970) and the alpha attenuation response (Blum, 1957;Wells and Wolf, 1960;Davidoff and McDonald, 1964;Milstein, Stevens, and Sachdev, 1969

“…abnormality in their patient, however, was still present when the plasma sodium-value had returned to normal, and they suggested the possibility of " cerebral hyponatraemia." In normal human females Margerison et al (1964) found a significant association between changes in mean abundancies of 7, 8, and 9 c./sec. activity in the E.E.G.…”

“…There are other hormonal changes which also have been observed to have two peaks in the menstrual cycle (Greene & Dalton, 1953;Dalton, 1959;Janowsky, Gorney & Mandell, 1967;Margerison, Anderson & Dawson, 1964;Bruce & Russell, 1962;Sargent & Weinman, 1966;Southam & Gonzaga, 1965). Although it has not been possible to relate the changes definitely to any one hormone, it is still possible to see how a hormonal change could affect the pitch estimates because of their known general effect on the body.…”

“…Indeed correlates have been sought in women between the variation in the sodium balance of the body and a change in the electrical activity of the C.N.S. as would be indicated by changes in the brain waves (Margerison et al 1964). Their work suggests that if such changes do occur during the menstrual cycle then they are not resolvable by e.e.g.…”

WYNN ABSOLUTE PITCH electrical properties of those cells required to convey the aural information from the input end of the cochlea to the brain itself. ACh is known to be one of the chemicals which aids the conduction of nerve impulses, the sodium/potassium ratio is likewise considered to be important to the conduction of electrical impulses (Margerison et al 1964). It appears likely therefore that the nervous system will be affected in some way by all these changes.…”

SUMMARY1. Longitudinal studies on absolute pitch estimates have been observed in one male and two female subjects.2. The female subjects underwent rhythmic variations in their estimates that were related to their menstrual cycles. One female subject, the more intensively studied of the two, also showed variations in her pitch estimates that were related to illness.3. Relevant correlations between the menstrual cycle and known biochemical parameters are mentioned which suggest that the fluctuations in the female estimates are governed by changes in the electrical activity of the auditory nervous system. 4. The male subject showed similar fluctuations in his pitch estimates. A rhythm of approximately 20 days was observed.5. A connexion between the fluctuations in the pitch estimates and the sex hormones in both the female and the male subjects is suggested as a possible explanation of the difference between two different types of absolute pitch.6. The hypothesis is extended to show how the adrenal corticosteroids could account for the changes in the pitch estimates that occurred with illness.
