A Leghorn chicken exposed to 9.29 GHz pulsed microwaves at 100 mi/om@ showed increased muscle activity on the exposed side and near paralysis on the opposite side, with full recovery after exposure ended.
Plain English Summary
Summary written for general audiences
A Leghorn chicken was exposed to 9.29 GHz pulsed microwaves at 100 mi/om@ while muscle activity was recorded with an 8-channel pen recorder. At radiation onset, muscle activity increased on the side facing the field and decreased almost to paralysis on the opposite side. After the field was turned off, the chicken recovered normal posture and muscle activity within seconds.

Quick Questions About This Study
A Leghorn chicken was placed in a wooden cege lined with Eccosorb and exposed to a 9.29 GHz pulsed microwave field at 100 mi/om@ with a pulse rate of 416 pps and pulse width of 2.35 psec.
On switching off the field the chicken recovered its normal posture after a few seconds and the muscular activity returned to the normal level observed prior to radiation.
A further consideration is that microwaves stimulate the area of impingement and create vasoconstriction which through the nervous system of the bird produces a contralateral effect, suggesting nerve interaction of a secondary character.
