Abstract

Rectangular pulse-modulated microwave radiation has been shown to produce auditory responses in mammals. It is therefore reasonable to explore the possibility of using microwave pulses to achieve an estimate of sensori-neural involvement in the objective evaluation of human hearing and to assess the presence of tumors or brainstem lesions in patients with neurological disorders. In this paper we shall show that microwave-evoked auditory response of cats closely resembles that evoked by acoustic pulse. We shall also give preliminary results obtained from electrodes fastened to the vertex of the skull after successive coagulative production of lesions in the inferior colliculus, lateral lemniscus, and superior olivary nucleus.

Main findings

Pulse-modulated microwave radiation produced auditory responses in cats that closely resembled responses evoked by an acoustic pulse. Preliminary results are reported using vertex skull electrodes after successive coagulative lesions in specific auditory brainstem structures.

Outcomes measured

Microwave-evoked auditory (brainstem) responses/potentials
Comparison of microwave-evoked vs acoustic pulse-evoked responses
Effects of induced brainstem lesions (inferior colliculus, lateral lemniscus, superior olivary nucleus) on recorded responses

Limitations

No exposure parameters (e.g., frequency, power/SAR, pulse characteristics) reported in the abstract
Sample size not reported
Results described as preliminary for lesion experiments
No quantitative outcome data provided in the abstract
