PERINATAL EXPOSURE TO 60-HZ ELECTRIC-FIELDS - EFFECTS ON THE DEVELOPMENT OF THE VISUAL-EVOKED RESPONSE IN RATS BIOELECTROMAGNETICS Jaffe, R. A., LOPRESTI, C. A., Carr, D. B., Phillips, R. D. 1983; 4 (4): 327-339

Abstract

Two independent series of experiments were performed on 114 male Sprague-Dawley-derived, albino rat pups, which represented 61 litters in experimental series I and 53 litters in experimental series II. Animals were exposed for 20 h/day from conception to testing (postnatal days 11-20) to a vertical, 65-kV/m, 60-Hz electric field or sham-exposed. Recordings of the visual-evoked response (VER) were obtained using a small silver ball electrode placed epidurally over the visual cortex. Visual stimuli consisted of 10-microseconds light flashes delivered at 0.2 Hz. Computer-averaged VERs were obtained and power spectral analyses (fast Fourier transform) were performed on the tapered (split cosine-bell window), averaged VERs. The expected age-related changes were clearly evident; however, a detailed analysis of VER component latencies, peak-to-peak amplitude, and power spectra failed to reveal any consistent, statistically significant effect of exposure to 60-Hz electric fields.
