Title: Investigation of effects of 60-Hz electric and magnetic fields on operant and social behavior and on the neuroendocrine system of nonhuman primates. Quarterly report, Scan and activity data for experiments 4 and 4A, [July 1, 1992--September 30, 1992]

Abstract

The objective of this program is to investigate behavioral and neuroendocrine effects associated with exposure to 60-Hz electric and magnetic fields (E/MF), using the baboon surrogate for the human. Baboon social groups were scanned and electronically monitored during Experiments IV and IVA. The social scan, form that the technicians used to identify baboon locations and proximity to other baboons: was used to gain a simple snapshot of the position of the baboons in their cage. The scans were taken hourly every morning and evening for a total of eight scans per side per day. This report covers in detail the scan and activity data-gathering process. A set of appendices is attached which include printouts of the data sets and adjunct material pertinent to interpreting the data. The supporting material is comprised of calendars and listings of major events that occurred during the scan and activity data collection.

  • The objective of this program is to investigate behavioral and neuroendocrine effects associated with exposure to 60-Hz electric and magnetic fields (E/MF), using the baboon (Papio cynocephalus) as a nonhuman primate surrogate for the human. Results from this program, along with information from experiments conducted elsewhere, could be used to estimate and evaluate the likelihood of deleterious consequences of human exposure to the electric and magnetic fields associated with electric power transmission. This report covers a series of three experiments (Experiments III, IV, and IVA) on the effect of combined 60-Hz E/MF on operant behavior. These experiments were a continuationmore » of previous investigations of 60-Hz electric field exposure on baboons.« less
  • A cohort of sixteen male baboons were assigned to electric and magnetic field (E/MF) exposure and sham-exposure. The social behavior subjects were simultaneously exposed to 60 Hz E/MF. Ten behavioral categories were measured. Each behavioral category was comprised of multiple molecular behaviors that could be objectively identified and counted. Six of the behavior categories were ``social``, in that interactions between subjected were involved. The remaining four were ``non-social`` and pertained to individual behaviors such as movements or postural stances.
  • This quarterly report covers the neuroendocrine Portion of Experiment IV. Serum melatonin concentration was measured in individual baboons, each implanted with a chronically indwelling venous cannula. As in Experiment III the system of six automatic blood samplers was used to achieve undisturbed, 24 hr per day, simultaneous blood sampling from six individual subjects. The objective of the neuroendocrine portion of Experiment IV was to determine if 30 kV/m electric and 1.0 G magnetic field (E/MF) exposure produced a 50% decline in nocturnal serum melatonin concentration. Other groups of subjects were tested concurrently during Experiment IV to assess E/MF effects onmore » group social and individual operant behavior. The results of these experiments will be covered respectively in the next two quarterly reports. The results of Experiment IV, as was the case with the result of Experiments III and IIIA, provide little or no evidence that E/MF exposure, under the conditions of these experiments, affects nocturnal serum melatonin concentrations of nonhuman primates. Together the negative results of Experiments III, IIA and IV indicate that day-time exposure of primates to slow-onset/offset, regularly-scheduled E/MF does not produce melatonin suppression, strongly suggesting that such exposure would not affect human melatonin either. However, before concluding that E/MF exposure in general has no effect on primate melatonin, nightime exposure needs to be examined, and the possibility, suggested by the Pilot Experiment, that fast onset/offset, irregularly-scheduled E/MF can completely suppress melatonin needs to be investigated.« less

  • The objective of this program is to investigate behavioral and neuroendocrine effects associated with exposure to 60-Hz electric and magnetic fields, using the baboon (Papio cynocephalus). Results from this program are used to estimate consequences of human exposure to the electric and magnetic fields associated with electric power transmission. Electric and magnetic field measurements for Experiment IIIA (Confirmatory), Experiment IV and Social Behavior portion of Experiment III are presented. The systems for the production and monitoring of the fields performed satisfactorily during Experiment IIIA and during all but the last part of Experiment IV. In Experiment III, two-way repeated analysesmore » of variance revealed statistically significant Group (Exposed and Sham Exposed) and Period (Baseline. Exposure, and Post-Exposure) main effects. Two significant Period by Group interactions were also found. Seven of the ten behavioral categories showed a main effect of Period. Two-sample t-test comparisons of the two groups for each period indicated that performance rates in two behavioral categories (Stereotypy and Posture) were significantly lower in the Exposure Group. In general, the Exposed subjects exhibited a trend of progressively lower performance rates across the three periods. Specific accomplishments reported in this document were: measurement of electric and magnetic fields for Experiments IIIA and IV, completed analysis of the Social Behavioral data from Experiment III, and a detailed discussion of statistical methods employed on the Social Behavioral portion of Experiment III, and hematology data were collected and recorded for Operant and Social Behavioral subjects for Experiment IV.« less
