12 Electromagnetic Fields in Biology and Medicine
We were only able to perform one-half of the intended experiment, but we were able to demon-
strate that for eggs exposed to 60Hz electric elds during incubation, the brain tissues exhibited
a signicant response to 50Hz elds but not to 60Hz elds, in agreement with the results from
commercially incubated eggs [23]. In contrast, the calcium ion efux from brains from chicks
exposed during incubation to 50Hz elds was not affected by either 50 or 60Hz elds. This
result indicates that some imprinting may have occurred during embryogenesis and organogen-
esis, thus altering responses to specic EMF treatments [29]. It is obvious from these results that
there may be inability to replicate ...
